HYDROSTATIC SYSTEM
PUMP REPAIR
Caution must be exercised after the control valve is swung away from the pump housing since this opens a
large cavity into the housing. Also during removal and installation of the control link pin, parts can be dropped
into the main housing, requiring total disassembly of the unit (refer to Fig. 23).

Figure 24.
Swing the control away from the housing as far as it will go to expose the cotter pin (refer to Fig. 24).
Remove the cotter pin, washer, and connecting pin. It is suggested that a piece of wire be inserted through the
eye of the cotter pin so the pin can easily be retrieved if it falls into the pump (refer to Fig. 25).

In preparation for reinstalling the control, place a new gasket on the housing, and place the orifice plate and O-
rings in the control (refer to Fig. 26).
Install the connecting pin through the control linkage and the feedback link on the swashplate with the headed
side toward the center of the pump. Use caution not to drop parts into the pump housing (refer to Fig. 27).
