Seat Removal
Valve and Seat Inspection
Inspect the valves and seats for any build-up of
materials. Valves should be cleaned with an ap-
propriate cleaning solvent to remove the material
on it.
† A seat should not be replaced unless
there are indications of valve leakage in
operation.
NOTE
Replacement
Lubricate the seat O-ring using a suitable lubri-
cant. By hand, using the seat tool (A10756-00),
carefully start the seat into the pocket for the seat.
† Carefully start the seat into the pock-
et. It may be easily cross threaded.
† Hand tighten the seat in place. Using
a torque wrench with a /8” (10mm) sock-
et, torque the valve seats to 15-20 lbs•in
(1.7-2.3 Nm).
NOTE
Valve Seat Torque
† Always use a torque wrench to torque the
seats in place. Over-torqueing the seats may
cause permanent irreparable damage to the
rear manifold.
Lubricate the valve O-rings with a suitable O-ring
lubricant. By hand, start the threads clockwise
of the valve into the pocket. Tighten using a 1/2”
(13mm) socket and torque to 15-20 lbs•in (1.7-2.3
Nm) after valve is down.
