1. Pull shaft (21) and bearing from housing (3).
2. Remove drive shaft bearing as follows:
a. Install a nine inch piece of 1-1/2" heavy wall tubing over drive shaft (21). The end of the tubing will rest
against the inner race of tapered roller bearing (22) and extend out beyond the end of the shaft.
b. Place the shaft and bearing with tubing into an arbor press with drive spline up. See Figure 11.
c. Press the drive shaft through the bearing. A 0.001 inch press exists between the shaft and bearing so
considerable force is required to remove the bearing from the shaft. DO NOT remove the bearing race
unless bearing (22) was found defective. Refer to Figure 12 for bearing race removal instructions. Use
special tool shown in Figure 5.
3. Remove retaining ring (23) and press shaft seal (24) out of the housing. Use a short piece of 1-1/2" heavy wall
tubing as a tool.

NOTE: All parts must be thoroughly cleaned and kept clean during inspection and assembly. Clean all removed
parts, using a commercial solvent that is compatible with the system fluid. Compressed air may be used in
cleaning, but it must be filtered to remove water contamination. Clean compressed air is particularly useful in
cleaning valve block passages.
