Clean the Transmission Suction Screen
(12x4 Quad Shift III Transmission Only)
The 12x4 transmission has a removable sump
screen located under the suction tube that will
require cleaning periodically. To remove the
suction screen, proceed as follows:
Drain the transmission oil.
Loosen and remove the four cap screws, 1, that
mount the suction tube block to the rear face of
the transmission. Push the tube out of the way to
access the suction port.

Remove the suction screen from the port and
clean it in a suitable solvent. Replace the screen
into the suction port.
Check the O ring on the front face of the suction
tube block to be sure that it is in good condition
and is positioned properly. Replace the O ring if it
is damaged. Reinstall the suction tube block
bolts and torque to 75 N⋅m (55 ft. lbs.).
IMPORTANT: The powershift transmission has a
non-removable suction screen that does not
require maintenance.

Check the Transmission Mounts
Check the rubber transmission mounts and
mounting hardware for condition and torque on
both the powershift and Quad Shift III

The Quad Shift III transmission is held in the front
frame of the tractor by four bottom mounts, 1,
and two top mounts, 2. Inspect the mounts for
deterioration and wear. Torque the lower
mounting bracket bolts, 3, to 224 N⋅m1 (165 ft.
lbs.) and the upper mounting bracket bolts, 4, to
397 N⋅m (293 ft. lbs.). Torque the mount bolts, 5,
to 280 N⋅m (205 ft. lbs.).
