Filter By-Pass Valve Replacement

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 by−pass valve hex plug (Fig. 80).

3. Remove the spring and poppet from the housing.

4. Do not interchange parts with another valve. The

spring used in the filter by−pass 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 1.280 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 O-ring)

into the housing. Tighten the plug to a torque from 30 to

70 ft.-lb (41 to 95 N-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.

Filter Reverse Flow Check Valve Replacement

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 reverse flow check valve hex plug

(Fig. 81).

3. Remove the spring and poppet from the housing.

4. Do not interchange parts with another valve. The

spring used in the reverse flow 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 1.280 inch

(3.25 cm).
