STEERING 4.1 4 Tracking Adjustment (Speed) Speed control limiter bolts C3559 Jam nuts Check rod end bushings for wear Check pintle lever tightness C3554 C3560 4-7 Tracking adjustment, or wheel speed, is set individually for L.H. and R.H. sides. If the operator complains the loader does not go in a straight line when the levers are pushed clear forward the limiter stops may need adjust- ment. 1 Raise the boom arms, engage the boom support pins and shut off the engine. Raise and block the loader securely off the ground. WARNING Never work under the boom arms without the boom supports engaged. 2 Remove the seat and hydrostatic shield.
Note the location of the steering control limiter bolts located front and rear of each steering control lever, just below the pivot point.. (fig. C3559) 3 Make sure the neutral adjustments are adjusted cor- rectly. Refer to pages 4- 4 ~ 4-6. 4 If and when all rod bushings and pivot points have been check for wear or binding, proceed with the wheel speed adjustment. 5 Start the engine and release the parking brake. Adjust the engine RPM to the full high idle position. Refer to Section 7 to verify engine RPM. WARNING Raise the loader securely off the ground before start- ing the engine.
6 Using an RPM surface speed measuring tool (Thomas P/N 43981) check each wheel speed in the for- ward and reverse direction. Repeat for opposite side. (fig. C3560) 7 Correct wheel speed is set evenly at 83 RPM forward and reverse for both sides. 8 If adjustment is necessary, loosen the jam nut (fig. C3559) and turn the limiter bolt in to increase wheel speed or out to slow it down. 9 Tighten the jam nut and retest the speed adjustment. Repeat if necessary. 10 Replace the seat and hydrostatic shield. Note: If the wheel speed does not meet the above specifi- cation, check the engine RPM. Refer to Section 7.
If the engine RPM checks out good you may need to check for hydrostatic problems such as drive motor seal leakage etc. Refer to Section 2 for testing procedures. 4-7
