Torque Limiter for the C2 Series Backhoe Loader (9) Adjustment screw. (10) Locknut.
Loosen locknut (10) and turn screw (9) clockwise in order to increase the flow. Turn adjustment screw (9) counterclockwise in order to decrease the flow. Note: A half turn of adjustment screw (9) will change the flow approximately 3.8 L/min (1 US gpm). Never, adjust screw (9) more than three and a half turns. Adjusting the screw (9) more may damage the internal spring. If the spring fails, the pump performance will be poor.
After the adjustment is made, tighten the locknut. Repeat Steps 13, 14, 15, 2, 17, and 16.
If the flow is not within the specification, then adjust the torque limiter. Stop the engine. Repeat steps 19 and 20. If the torque limiter is not within the specification after several attempts, then rework the torque limiters. Go to the next test in order to Rework the Torque Limiter. Repeat the test and adjust for the torque limiter after you rework the torque limiter.
When the flow is within the specification, remove the test equipment.
Remove hose (6) from the 6V-8946 Reducer Assembly. Remove 6V-9831 Cap Assembly from tube (5). Place a new O-ring onto the fitting and reinstall hose (6) to tube (5) .
Remove hose (4) from the 6V-8946 Reducer Assembly. Remove 6V-9832 Cap Assembly from elbow (3). Place a new O-ring onto the fitting and reinstall hose (4) to elbow (3) .
Replace hoses (4) and (6) into the two retainers (8) on the boom for the two hoses. Reinstall the four bolts (7). There are two bolts on each retainer (8). Reinstall the retainers (8) on the boom for the hoses.
Replace the floorplate. Reinstall the four screws that hold the floorplate in place.
Replace the floormat. Reinstall the four screws that hold the two plates for the floormat. There are two screws on each plate. The plates are located at the edge of each door in the cab.Rework the torque limiter
Note: If the torque limiter cannot be set within the specification, then replace the torque limiter.Note: This procedure will not increase the lifting capacity of the machine.
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure the bucket and/or all of the attachments have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to
