Filter By-Pass Valve Replacement (Fig. 83)
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. Remove the filter bypass valve hex plug.
3. Remove the spring and poppet from the housing.
4. Do not interchange parts with another valve. The
spring used in the filter bypass valve is identified by a red
dye mark, and requires a force of approximately 2.2 lb
(9.8 N) to compress it to a length of 1.28 inch (3.25 cm).
5. Inspect the poppet and mating seat in 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
30to70ft-lb(41to95N-m).
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.
In-line Filter Check Valve Replacement (Fig. 84)
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch.
2. Remove the in--line filter check valve hex plug.
3. Remove the spring and poppet from the housing.
4. Do not interchange parts with another valve. The
spring used in the in--line filter check valve is identified
by a blue dye mark, and requires a force of approximate-
ly 0.3 lb (1.3 N) to compress it to a length of 1.28 inch
(3.25 cm).
5. Inspect the poppet and mating seat in 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
30to70ft-lb(41to95N-m).
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.
