5.5 Maintenance & Adjustments Continued
5.5.1.3 Cradle Shifting Valve:
The cradle shifting valve mechanism has been adjusted at the factory and should
not require adjustment during normal use of the machine. If, however, the valve
or other components need to be serviced, the following guidelines should be used
to position the valve properly on its mounting plate:
a. Assemble the shift spool to the valve body.
b. Position valve on the mounting plate and install mounting bolts. Finger tighten
bolts to allow moving if required.
c. Slide the valve spool to its neutral position (5/16" extended).
d. Slide the valve assembly until it is centered between stops. Tighten mounting
bolts to their specified torque.
e. Adjust the stop bolt so that when the valve shift lever is touching the stop bolt
there is approximately 1/32 inch clearance between the shift spool flange and
the stop welded to the valve plate.
f. Move the shift lever to the other side and adjust the other stop bolt in the same
manner.
g. Check that the shifting action is smooth and that no binding occurs.
h. Install spring and reconnect hoses.
