Maintenance and Adjustment Procedures
Regular maintenance and precise adjustments are critical for the longevity and optimal performance of your Case tractor. This section details various maintenance tasks and specific adjustment procedures.
Checking and Adjusting Backlash
Proper adjustment of backlash is essential for the smooth operation and durability of mechanical components. Follow these steps carefully to ensure correct settings.

- مرحلہ 31: Install the outer thrust washer.
- مرحلہ 32: Install two 3/8" bolts and flat washers. Tighten the bolts until the pump drive gears are tight against each other (zero backlash). Measure the distance from the top face of the outer thrust washer to the bottom of the counterbore of the pump body. Record this measurement.
- مرحلہ 33: Add 0.006" (0.152 mm) to the measurement obtained in Step 32. This calculated value represents the required shim thickness. The correct pump drive gear backlash should be between 0.003 to 0.005 inches (0.076 to 0.127 mm).
- مرحلہ 34: Install the retainer plate against the shims.
- مرحلہ 35: Install and tighten the retainer plate screws to a torque of 25 to 30 ft. lbs. (34 to 41 Nm).
