Figure 46: Valve Seat Torque

Hand tighten the seat in place. Using a torque

wrench with a 3/8-inch (10mm) socket, torque the

valve seats to 15-20 lbs•in (1.7-2.3 Nm).

Lubricate the valve o-rings with a suitable o-ring

lubricant. By hand, thread the valve into the pocket

in a clockwise direction. Tighten using a 1/2-inch

(13mm) socket and torque to 15-20 lbs•in (1.7-2.3

Nm) after valve is down.

Removal

Using the valve seat removal tool (A11922-00),

engage the four (4) pins on the tool to the corre-

sponding four (4) hole pattern in the top of the

valve. Tighten knurled thumb screw and tool to

engage 1-2 threads on the valve cap. This will aid

in pulling the valve from its bore once it is loose.

Using a 1/2-inch (13mm) socket, remove the valve

by turning clockwise until fully unthreaded. Pull

the valve assembly from the pocket. Pull valve

straight out.

Using seat removal tool (A10766-00), insert the

smaller hex end into the valve cavity to engage

the seat hex. Using a 3/8-inch (10mm) socket,

remove the seat by turning counter-clockwise.

Replacement

Clean seat and valve pocket thoroughly. Lubricate

valve pocket, o-rings on seat and valve assem-

blies with A11545-00 lubricant. Carefully start

the seat assembly into the valve pocket. Hand

tighten in place. Using a torque wrench with a

3/8-inch (10mm) socket, torque the valve seat to

15-20 lbs•in (1.73-2.3 Nm). Next place the valve

onto the four prongs of the valve removal tool

and insert into the valve pocket. Tighten by hand

as far as possible. Tighten fully using a torque

wrench with a 1/2-inch (13mm) socket and torque

to 15-20 lbs•in (1.7-2.3 Nm) after valve is down.
