Modifications may weaken the integrity of the grapple and may impair the function, safety, usable life, and perfor-mance of the grapple.? DO NOT IMPROPERLY USE GRAPPLEGrapples are designed to be used as material handling tools for loading or transporting material that can be safely contained in the bucket the grapple is mounted on. Uses outside this method of material handling must be approved by Grabtec.2MODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETNOTE335661L92883771R8335661R71L9287A mounting kit includes parts for each the left and right side of the bucket. Each side is usu-ally identical to the other. The purpose of the diagram is to identify various parts of the kit. The spacers and alignment pins are used only during installation of the kit. They are pur-chased separately from the mounting kit. Your mount kit either included hook plates that are shaped to fit your bucket or the hook plates are universal and need to be trimmed to fit (see section later in this manual, pages 9-10.)ITEM DESCRIPTION QTY / KIT1L HOOK PLATE, LEFT 21R HOOK PLATE, RIGHT 22 DOUBLER PLATE (NOT REQ’D FOR ALL KITS) 23 COLLAR (1.28” ID) 45 SUPPORT PLATE 26 SET SCREW, 3/4 X 4 47 JAM NUT, 3/4 8ITEM DESCRIPTION QTY / KIT8 SPACER, 1” THICK, 2 X 4 49 ALIGNMENT PIN (1.27” DIA. x 12 LONG) 2Mount KitAssembly Kit(Optional)NOTE A:Shape and appearance of items 1L, 1R and 2 will depend on the application.

Some kits have 4 small doubler plates, with one doubler for each hook plateMODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETFig. 1TORQUETUBEASSEMBLYHOOK PINHOOK PLATECOLLARALIGNMENT PINSPACER7”4STEP 1 (See Figure 1)This step is best done on a large bench with the mount kit parts and torque tube assembly upside down. Slide the hook pin of the torque tube assembly into each “hook” of the hook plates. Slide the alignment pin through the long tapered sleeve of the torque tube and align it with the two 2” diameter holes of the hook plates. Slide a collar onto each end of the alignment pin and into the large holes of the hook plates so that the collars are flush with the inside of the hook plates. Insert one 1” thick spacer on each side of the torque tube and clamp the hook plates to the torque tube so that the space between the hook plates is 7”.MODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETSTEP 2 (See Figure 2)Once the mounts have been clamped together, they can be placed on the bucket. Each mount must be square with the other and square to the bucket so that the grapple does not bind as is rotates. The best results can be achieved by running a long 1-1/4” shaft or pipe through the grapple pivot holes on the torque tubes. The best center-to-center distance to use depends on the width of the grapple and also the presence of any obstructions on the back of the bucket, such as gussets or splash guards. Use the following table to help deter-mine what center-to-center position of the mounts would work best in your application. If you need help determining what Model you have, see page 29.Fig. 21-1/4” DIA.

However, the hydraulic sup-ply hoses that are included with your grapple (see Items 2 & 3 on page 27) are only long enough for the standard center-to-center spacing.MODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETFig. 4STEP 5 (See Figure 5)Referring to the mount diagram earlier in this section and Figure 5, assemble the support plates within the hook plates. Have the set screws adjusted so that the support plate is as far down as possible.Fig. 5SUPPORT PLATEFig. 3HOOK PLATETACKTACK6STEP 3 (See Figure 3)Once the mounts are square and properly spaced, tack the four hook plates to the bucket. It may also be helpful at this time to double check just where the tips of the grapple teeth will end up with the mounts in their current position. DO NOT TACK OR WELD THE COLLARS YET.STEP 4 (See Figure 4)Remove clamps, spacers, collars, alignment pins and long alignment shaft from the mounts. Tilt the bucket forward and support it. Weld the hook plates (and doubler plate if appli-cable) to the bucket. A welder using 0.045 wire and capable of 250-300 amps works best. A 3/8” single-pass, continuous fillet weld is required for all parts that are being welded to the bucket.MODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETSTEP 6 (See Figure 6)With the bucket tilted forward, re-install the torque tube assemblies into the mounts. The downward tilt of the bucket will keep the weight of the torque tubes properly engaged in the hooks of the hook plates. Also install the collars into the hook tubes with the help of the alignment pin. The inside surface of the collars should be flush with the inside of the hook plates.Fig. 6 Fig. 7Fig. 8STEP 7 (See Figure 7)Adjust the set screws on each side of the mount until the support plate is supporting the torque tube evenly AND the alignment pin can be twisted with your fingers.STEP 8 (See Figure 8)Once you are comfortable with the adjustment position of the set screws and the alignment pin is still free to turn, tack the collars in their permanent position. If the tacks cause the col-lars to tighten up on the pin, a few taps with a hammer on the collars should re-align them.EQUAL CONTACTTACKALIGNMENT PINCOLLAR SUPPORT PLATE7MODEL ‘GC’ GrappleGrabTecOwner’s ManualINSTALLING MOUNT KITONTO THE BUCKETSTEP 9 (See Figure 9)Weld the collars in their permanent position. They can be welded on the outside only as shown, since they are flush with the hook plates on the inside.Fig. 9 Fig. 10STEP 10 (See Figure 10)The alignment pin used in Steps 1-8 is approximately 0.025” larger than the actual retain-ing pin. If all has been done correctly up to this point, you will find that the retaining pins are loose enough to be easily pushed in by hand. It is advised that you use the set screws to adjust the torque tube slightly upwards so their is a slight drag on the retaining pins. This ensures that the pins are contacting the torque tubes, but they will still be easy to remove by hand when the grapple is dismounted from the bucket. See the section titled “Adjustment of the Support Plates” later in this manual for a more information.RETAINING PIN8MODEL ‘GC’ GrappleGrabTecOwner’s ManualTRIMMING “UNIVERSAL” MOUNTSTO FIT THE BUCKETSTEP 1 (See Figure 1)The positioning template is furnished in 2 parts. Tack weld the two parts together as shown. NOTEIGNORE THIS SECTION IF YOU RECEIVED A MOUNT KIT MADE FOR YOUR SPECIFIC BUCKET (which hap-pens 99% of the time - this Section is rarely needed) Grabtec Inc will make every effort to provide a Mount Kit that is designed to fit your bucket and will locate the grapple in the proper poistion. However, rare cases do occur when a “universal” mount kit is all that can be supplied. The four 3/4” thick hook plates that are included in the mount kit will need to be trimmed to fit the profile of your bucket and to position the grapple properly in respect to the cutting edge of the bucket.9Fig. 1 Fig. 2Top HoleTack Weld the two parts togetherPositioning TemplateTip APPROX. 3"Top HoleTipSTEP 2 (See Figure 2)Position the template over the bucket so that the tip of the template (which represents the tips of the grapple teeth) is in the desired position. Please note that the tip should be ap-proximately 3” above the cutting edge. If the tip is inside the bucket, or within 1” of the cutting edge or cutting edge bolt, it is possible for the grapple teeth to contact them when the grapple is dismounted. VERY IMPORTANT - If the depth of your bucket is less than 40”, (See Figure 2) the grapple will probably have to be positioned so that the teeth are actu-ally ahead of the cutting edge. This is because it is likely that when the bucket is tilted all the way back and the loader is all the way down, the Mount kit may actually contact the front tires. Tilt the bucket back and use the template to see how much clearance there is between the front tire and the bucket before finalizing exactly where the grapple can be located.DEPTHMODEL ‘GC’ GrappleGrabTecOwner’s ManualTRIMMING “UNIVERSAL” MOUNTSTO FIT THE BUCKET10IGNORE THIS SECTION IF YOU RECEIVED A MOUNT KIT MADE FOR YOUR SPECIFIC BUCKET (which hap-pens 99% of the time - this Section is rarely needed)30"41"45°Fig. 3Top HoleUniversalHook plateHook plateafter trimmingFig. 4Top HoleSTEP 3 (See Figure 3)Another way to know the relation between the top hook plate hole and the position of the grapple teeth is by taking a few measurements. In Figure 3, notice that the tip of the grap-ple teeth will be 41 inches below the top hole and 30 inches in front of it. The proper angle of the top edge of the hook plate is 45 degrees as shown. Typically, you want the grapple teeth 2-3 inches above the very front of the cutting edge. From this imaginary point, mea-sure back 30 inches and up 41 inches and you will know approximately where the top hole of the hook plates has to be. This method is satisfactory, but the use of the positioning tem-plate as described in Step 2 is the preferred method, since it gives a better picture of just where the grapple will be once its installed.STEP 4 (See Figure 4)Once you know where the top hole of the hook plate should be located on your bucket, you must transfer the profile (shape) of the bucket onto the universal hook plates so that they can be trimmed to fit. Please note that the shape of the trimmed hook in Figure 4 is for dem-onstration only and may not look anything like the shape required for your bucket.MODEL ‘GC’ GrappleGrabTecOwner’s ManualASSEMBLY OF GRAPPLE ONTO BUCKETWARNINGUSE A CRANE OR A HOIST TO LIFT ALL ITEMS THAT WEIGH MORE THAN 50 LBSSTEP 1 (See Figure 1)Position torque tube assembly onto the mount that is welded on the bucket and secure the torque tube with the retaining pin.Fig. 1 Fig. 2 Fig. 3NOTEReviewing the Parts Listing found later in this Manual will assist in relating the part descriptions in the Instructions with items used for assemblySTEP 2 (See Figure 2)Using a 1-1/4” diameter pivot pin, connect the pivot assembly to the torque tube. Secure the pivot pin using a 3/8 x 2-1/2 bolt and nylock nut.STEP 3 (See Figure 3)In preparation for the installation of the cylinder, lift and support the pivot assembly as shown.CAUTIONThe zero-maintenance feature of the pivot pins and pivot housings of the Grabtec grapple is dependant upon proper care when installing the pins. Please read the “Maintenance” section of this manual before installing any of the pivot pins.11STEP 4 (See Figure 4)Install the cylinders between the torque tube and pivot assembly as shown. The two cylin-ders that came with the grapple are identical, there is not a right and a left cylinder. Secure the pins using 3/8 x 2-1/2 bolts and nylock nuts (not the snap lock pins that are in the pic-ture).MODEL ‘GC’ GrappleGrabTecOwner’s ManualFig. 412STEP 5 (See Figure 5)Bolt the outer tooth bars to the center tube using (8) 3/4 x 2 bolts and top-lock nuts.

Be sure to use a hardened flat washer under the head of the bolt and under the nut. MODEL ‘GC’ GrappleGrabTecOwner’s ManualFig. 8Fig. 9 Fig. 10STEP 9 (See Figure 9)Install the stand legs using the 3/4” diameter clevis pins and hairpin cotters. STEP 10 (See Figure 10)Install supply hoses and tees that go inbetween the cylinders. The lengths of these hoses depend on the grapple model. Use the hose connection sketch on page 27 as a guide. It is important that each tee is supplying the proper ports on the cylinders so that the cylinders work together. A short piece of hose wrap (26” long) should go between the cylinder ports and the hose clamp on the back of the torque tube. Longer lengths of hose wrap can be installed between the hose clamps and the tees. The position of the tees (bucket center, left, or right) will depend on where the loader’s auxiliary hoses are located on the loader boom. 13MODEL ‘GC’ GrappleGrabTecOwner’s ManualSTEP 1(See Figure 1)Drive bucket over level, hard ground and tilt it forward as shown. Move the parking stands to their park position, making sure that the pad of the stand is facing the ground.QUICK-DISCONNECTING THE GRAPPLE FROMTHE BUCKETSTEP 2 (See Figure 2)Note how the bucket is tilted downward enough so that the retaining pin is below hook pin. This will ensure that the weight of the grapple is restrained by the hook pin. Pull out the re-taining pins that secure the grapple to the mounts. If the pins are difficult to remove, it may be necessary to adjust the support plates. See the section titled “Adjustment of the Support Plates” found later in this manual.WARNING?

STAND TO THE SIDE.14Fig. 1 Fig. 2HOOK PINHOOK PINRETAININGPINMODEL ‘GC’ GrappleGrabTecOwner’s ManualFig. 3Fig. 4Fig. 5STEP 3 (See Figure 3)Disconnect the grapple hydraulic hoses from the wheel loader’s auxiliary supply. For some large and deep-bottom buckets (deeper than 43”), it may be best to leave the grapple hydraulics connected thru Step 5. This way the grapple cylinders can be used to help dis-engage the grapple from the hooks on the bucket. REMEMBER to disconnect hoses before backing awaySTEP 4 (See Figure 4)Lower the bucket and grapple to the ground so that the stand legs and the outer curved edge of the teeth touch the ground at about the same time.QUICK-DISCONNECTING THE GRAPPLE FROMTHE BUCKETSTEP 5 (See Figure 5)Rotate the bucket to un-hook the mounts from the hook pins of the grapple and back away. With some large and/or very deep buckets, it may be necessary to actuate the grapple cyl-inders to aid in disconnecting the hook pins from the bucket mounts.15MODEL ‘GC’ GrappleGrabTecOwner’s ManualSTEP 3 (See Figure 3)Insert the retaining pins that secure the grapple to the mounts. If the pins are difficult to in-stall, it may be necessary to adjust the support plates. See the section titled “Adjustment of the Support Plates” found later in this manual.STEP 2 (See Figure 2)Hook the mounts into the hook pins of the grapple and begin rotating the bucket until the grapple is just slightly lifted off the ground and the weight of the grapple is still supported by the hook pins.QUICK-CONNECTING THE GRAPPLE TO THE BUCKETSTEP 1 (See Figure 1)Approach the grapple with the floor of the bucket nearly straight up and down.16Fig. 1 Fig. 2HOOK PINHOOK PINFig. 3MODEL ‘GC’ GrappleGrabTecOwner’s ManualQUICK-CONNECTING THE GRAPPLE TO THE BUCKETSTEP 4 (See Figure 4)Connect the grapple hydraulic hoses to the wheel-loaders auxiliary supply.STEP 5 (See Figure 5)Place the stand legs in their store position.17Fig. 4Fig. 5MODEL ‘GC’ GrappleGrabTecOwner’s ManualADJUSTMENT OF THE SUPPORT PLATESThe Grabtec grapples have a unique feature in that they can be quickly disconnected from the bucket by removing two pins. There are two critical requirements that allow the pins to be removed easily (by hand). The first is that the mounts were installed correctly and that the collars that the pins slide through are properly aligned with the grapple. The second is that the support plates are adjusted correctly. SUPPORTPLATESET SCREWJAM NUTRETAINING PINTO ADJUST THE SUPPORT PLATES UPWARDLoosen the lower jam nut. Turn the top jam nut clockwise while keeping the set screw from turning. When proper adjustment is achieved, tighten both jam nuts.NOTEThe photo below shows the grapple when the bucket is flat on the ground. For best results, adjustment of the support plates should take place when the weight of the grapple is being supported by the hook pins, as shown in Fig 2 of “Quick Disconnecting the grapple from the Bucket” on Page 14.TO ADJUST THE SUPPORT PLATES DOWNWARDLoosen the top jam nut. Turn the lower jam nut counter-clockwise while keeping the set screw from turning. When proper adjustment is achieved, tighten both jam nuts.FUNCTIONWhen turned in the proper directions, the jam nuts and set screws can raise or lower the support plate. The support plate is “supporting” the grapple. When the support plate is moved, the grapple rotates about the hook pin and the upper holes in the mount that the re-taining pin slides through can be better aligned with the long sleeve in the grapple. As the alignment improves, the retaining pin is more easily installed (or pulled out).HOOK PIN18MODEL ‘GC’ GrappleGrabTecOwner’s ManualMAINTENANCEThe pivots on each end of the cylinders and the main pivots for the grapple frame are equipped with zero-maintenance bushings. There are no grease zerks on the grapple. Each end of the bushing housings are equipped with wiper-style dust seals to keep out debris. This pin system has proven to provide years and years of service in severe duty environ-ments, provided the following precautions are met:NOTE? IF YOU REMOVE A PIVOT PIN, MAKE SURE IT IS CLEAN AND DRY BE-FORE YOU REINSTALL IT.? IF YOU REMOVE A PIVOT PIN, DO NOT PERFORM ANY GRINDING OR WELDING THAT WOULD ALLOW PARTICLES TO ENTER THE BEARING HOUSING.? DO NOT ATTEMPT TO LUBRICATE THE PINS WITH ANYTHING. ? IF A DUST SEAL (WIPER SEAL) THAT PROTECTS THE BEARING HOUS-ING IS DAMAGED, REPLACE IT.? DO NOT REPLACE A PIVOT PIN WITH ANYTHING OTHER THAN A GRABTEC PIVOT PIN MADE FOR YOUR GRAPPLE MODEL. THE EX-TREMELY DURABLE AND HARD CHROME FINISH OF THE GRABTEC PINS IS IMPORTANT FOR THE LIFE OF THE BUSHINGS AND FOR THE RESISTANCE TO CORROSION IN THE PIN HOUSING.PROCEDURE INTERVAL NOTESCheck for hydraulic fluid leaks Daily Look at hose connections and hose fittingsCheck bolt tightness Daily Torque 3/4” nuts to 310 ft-lbs.Check for build-up around pivot areas Daily Remove ice, ground hay or any other debris from all pivot areas.19MAINTENANCE PROCEDURESMODEL ‘GC’ GrappleGrabTecOwner’s ManualPARTS INDEX20DRAWING ID#:PART INDEXPRODUCT MODEL: DRAWING REVISION:DRAWING DATE:-2/12/2009GCGC-S3TOOTH TUBEPage 23-24PIVOT ASSEMBLYPage 22THIS DRAWING)(NOT SHOW ONHOSES & FITTINGSPage 27MOUNT KIT Page 28TORQUE TUBE Page 21HYDRAULIC HOSESAND FITTINGS CYLINDERPage 25-26MODEL ‘GC’ GrappleGrabTecOwner’s ManualPARTS21ITEM NO.

The composite bushings located at cylinder and grapple pivot points are warranted against breakage or loss of their self-lubricating properties for three years or 5,000 hours, whichever comes first. Refer to the Maintenance section of the Owner’s Manual for proper care and precautions concerning the pivot bushings. The warranted coverage on the grapples or pivot bushings is for the parts only, not for labor to disassemble or reas-semble the grapple or to remove or reinstall the bushings or for shipping costs.If Grabtec installs the mounts on the bucket, Grabtec warrants the mounts against faulty design, ma-terial, or workmanship for a period of one year from date of delivery or 2,000 hours, whichever comes first. If Grabtec does not install the mounts, Grabtec warrants the mounts against faulty material for a period of one year from date of delivery or 2,000 hours, whichever comes first.If Grabtec provides mounts that were designed with information supplied by the customer, Grabtec will not warranty the mounts against improper fitment. Grabtec will make every effort to design mounts that fit with minimal reshaping, but accepts no responsibility for the customer’s ability to take accurate measurements of the bucket. If Grabtec provides mounts based on the fact that the custom-er’s bucket is one that Grabtec has previously designed mounts for, Grabtec accepts no responsibil-ity on manufacturing tolerances or design changes to the bucket made by the bucket manufacture that result in mounts that do not fit without a significant amount of reshaping.OEM components not manufactured by Grabtec are warranted by Grabtec against failure from im-proper installation for one year from date of delivery date. Examples of OEM components would be cylinders and cylinder components, hose clamps, hoses, and assembly hardware such as bolts and nuts.Dealer labor rate charges on approved repairs shall not exceed 70% of dealer regular hourly rate. Overtime charges need prior written approval. Claims received 30 days past the repair date will not be considered for warranty.Warranty is void if grapples are modified in any manner without PRIOR expressed written permission from Grabtec.GrabTecOwner’s ManualRETURN POLICY32RETURNED GOODS POLICY – PARTSItems SHIPPED in errorGrabtec will accept returned items, with prior approval of Grabtec (see RGA paragraph below), within 30 days after shipment without a restocking charge, freight collect.Items ORDERED in errorWhen parts are incorrectly ordered and returned to Grabtec, the customer is responsible for freight costs and a 15% restocking fee.When parts are purchased without reference to a model or serial number and returned to Grabtec, the customer is responsible for freight costs and a 15% restocking fee.RGA- Returned Goods AuthorizationAll return items must have prior approval of Grabtec and be assigned an RGA (Returned Goods Au-thorization) number by either the Grabtec sales or parts department and must be returned within 30 days of request.1242 Arizona AveLarchwood, IA 51241712-477-2675888-857-8952712-477-2500 FAX
