Seat Replacement
Lubricate the o-ring on the seat assembly using
a suitable lubricant, then by hand, using the seat
removal tool (A10766-00), carefully start the seat
assembly into the pocket of the manifold.
Hand tighten the seat in place. Using a torque
wrench with a 3/8" (10mm) socket, torque the
valve seats to 15-20 lbs•in (1.7-2.3 Nm).

Always use a torque wrench to torque
the sets in place. Over-torquing the sets
may cause permanent unrepairable dam-
age to the manifold.
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" (13mm) socket and torque to 15-20 lbs•in
(1.7-2.3 Nm).
FLUID TUBE ASSEMBLY
Insert fluid tube into the turbine body bore from the
back side. Install and tighten the four (4) SSF-3137
screws to a final torque of 7-10 lbs•in (0.79-1.13
Nm). Install 79001-05 o-ring on to the exposed
end of the fluid tube. Make sure this o-ring is not
damaged. Leaks will occur if the item is damaged.
Inspect the fluid tube outlet end to make sure it
is centered in the shaft bore. Mis-alignment may
cause fluid tube to touch rotating shaft or bell cup
which may result in turbine failure or fluid tube
damage. If tube is bent or otherwise damaged,
replace with a new part.
