Section IV - TRANSAXLE DISASSEMBLY
PUMP & SWASHPLATE DISASSEMBLY
Shown in Figure 4.23 are the components of the pump
and swashplate assembly. Familiarize yourself with all
components and their order of assembly before proceed¬
ing further.
NOTE:
The components in Figure 4.23 are shown in their normal
operating position (i.e., "up"). Disassembly of these com¬
ponents will take place with the upper case housing up¬
side-down on the workbench.
Separate, clean and inspect all components. Measure
thrust bushings for minimum thickness -1.3mm (0.05
inch). Inspect surfaces of all components individually -
they should be free of rust, pitting, scoring, etc. to be
serviceable. Replace parts as required.
