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.
