Bypass Valve Easy Ride Valve
Inspect the check balls (or poppets) and mating seats in
the center section for damage or foreign material.
Position the transmission so that the check valve port will
be in the upright position (as shown) and install the check
ball (or poppet), spring and plug (with o-ring) into the center
section. Make sure the plug stem is properly positioned
into the poppet or damage and failure will occur. Be certain
the check ball does not fall into the closed loop passage.
Torque the plug to 15-20 ft.lbs (20-27 Nm).
Turn the unit over and repeat the procedure for the other
side.
Bypass Valve
Remove the bypass valve plug with a 9/16" hex wrench.
Remove the bypass valve plug, spool and spring from the
transmission center section.
Inspect the valve spool and mating bore in the center
section for damage or foreign material. The spool must
move freely. It is recommended that the o-rings be re-
placed.
Retain the valve spring to the valve spool with petroleum
jelly. Install the valve spool, spring and plug (with o-ring)
into the center section. Torque the plug to 7-10 ft.lbs.
(9.5-13.5 Nm).
Depress the bypass valve several times to insure that it
operates smoothly and fully closes. The bypass “button”
should extend from the hex plug approximately 0.22"
(5.588 mm) when fully released (closed).
Easy Ride Valves
Remove the Easy Ride valve plug with a 11/16" open end
wrench or socket.
Remove the spring, piston and sleeve from the center
section.
Inspect the piston nose for damage.
Inspect the piston sleeve and spring for damage. The
piston should slide freely in the sleeve, but should fit tight
enough to create a vacuum.
Inspect the valve seat in the center section for damage. If
the valve seat is damaged the center section must be
replaced. Refer to the Major Repair section of this manual.
Install the piston, sleeve and valve spring.
Install the hex plug and torque to 15-20 ft.lbs. (20-27 Nm).
