INSPECTION
1. Inspect gear teeth for excessive wear or damage.
2. Measure the thickness of the differential gear thrust washers. Replace washers that exceed the minimum thickness. See "Specifications," Chapter 3.
3. Inspect the differential pinion shaft and gears for excessive wear. See "Specifications," Chapter 3.
4. Inspect the drive pinion to ring gear tooth wear pattern. See "Specifications," Chapter 3, for wear indications and shimming adjustments.

5. Inspect the bearings for excessive wear or binding when rotated by hand.
ASSEMBLY
NOTE: When the drive pinion and ring gear are reused, assemble using the same shims as removed. When the drive pinion and ring gear are replaced, adjust the shims as described below. The ring gear and pinion are serviced only as a matched set and must be rep/aced together.
If the drive pinion and ring gear are replaced:
The drive pinion and ring gear are identified by an assembly number which is stamped into the end of the drive pinion gear and on the circumference of the ring gear, Figure 14. In addition, a "Value of Error" number is also stamped into the end of the pinion gear, Figure 14. This number is prefixed with a ( + ) or ( - ) to indicate the amount of error from zero adjustment. If the value of error is greater on the new pinion than on the old

A. DESCRIPTION AND OPERATION
A hydraulic gear type pump is mounted on the right side of the engine, Figures 56 and 57. The pump is driven by the engine idler gear located on the front of the engine. The Model 1920 tractor uses a 7.8 gpm (29.5 Ipm) pump and the Model 2120 tractor uses a 9.3 gpm (35 Ipm) pump.
The tractors use a suction spin-on type hydraulic filter located on the right hand side of the rear axle center housing, Figure 58.
The hydraulic pumps are the conventional gear type design and are serviced only as a complete assembly.
