Charge Pressure Relief Valve
1. Park the machine on a level surface, lower cutting
units, engage parking brake and stop the engine.
2. Remove the charge relief valve hex plug (Fig. 33).
3. Remove the spring and poppet from the housing.
4. Do not interchange parts with another valve.
NOTE: The shim(s) which may be i
nstalled between the
spring and plug may remain inside the plug, being held
by an oil film. Make sure the same number and thick-
ness of shims is installed when reassembling the parts
unless shims need to be added or removed to adjust the
pressure setting.
5. Inspect the poppet and mating seat i
n the end cap for
damage or foreign material.
6. Reinstall the poppet, spring and plug (with shims and
o-ring) into the housing. Tighten the plug to a torque of
30 to 70 ft-lb.
7. Before starting the engine check the oil level in the
differential housing and add the correct oil as necessary.
Start the engine and let it run for one to two minutes,
then turn the engine off and check the oil level again.
Check the transmission for leaks.
