14 Transmission Tear-Down
Disassembly
14 - 10
12. Remove the axles (Figure 11) from the upper case.
Examine the components for any signs of damage or
wear, and replace as needed.
13. See Figure 11. To remove the axle bearing(s), first
remove the seal. Then remove the snap ring and
carefully drive the bearing out being careful not to hit
the balls or their cage. Examine it carefully for any
signs of damage or wear. It should turn over freely
with no roughness.
14. Remove the small round filter that separates the two
sections of this transmission.
15. Using a 12mm socket, loosen and remove the three
bolts that hold the charge pump housing in place
(Figure 12). Carefully lift & remove the housing from
the center section (Figure 13). Remove the rotors
and inspect for wear or damage. Any unusual
scratches or wear will require replacement.
• The charge and implement relief valves can be
removed and inspected. Be careful not to mix up the
springs between the two valves. Note that the
plungers and springs are different sizes and will not
interchange (implement spring is heavier). Again
look for any signs of gouges on the valve itself or
damage to the springs, replacing as needed. Be sure
to keep track of the ball check valve if it was removed
for cleaning.
