PUMP REPAIR
Remove the bronze bearing plate and the pilot ring from the cylinder block. If the pilot ring remains with the
bearing plate, remove it at this time (refer to Fig. 9).
Figure 9.
Figure 10.
The tapered bearing must now be removed from the shaft. A bearing puller should be used that will pull
against the inner race of the bearing. A spacer is required to protect the slot in the end of the pump shaft from
the puller screw. Protect the face of the cylinder block during this operation (refer to Fig. 10).
Figure 11.
Figure 12.
After removal of the bearing, slip the spacer out of the bore in the cylinder block (refer to Fig. 11).
Place the pump horizontally in preparation for removal of the cylinder block assembly (refer to Fig. 12).
Slide the cylinder block assembly off the shaft while holding the external end of the shaft (refer to Fig. 13).
