ADJUSTMENTS
ADJUSTMENT - TRANSFER SHAFT BEARING
(1) Use Tool L-4434 to remove the retaining nut
and washer. Remove the transfer shaft gear using
Tool L-4407.
(2) Install a 2.29 mm (0.090 inch) and a 1.39 mm
(0.055 inch) gauging shims on the transfer shaft
behind the governor support.
(3) Install transfer shaft gear and bearing assem-
bly and torque the nut to 271 N´m (200 ft. lbs.).
(4) To measure bearing end play:Attach Tool
L-4432 to the transfer gear.
(5) Mount a steel ball with grease into the end of
the transfer shaft.
(6) Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
(7) Using a dial indicator, measure transfer shaft
end play.
(8) Refer to the Transfer Bearing Shim Chart for
the required shim combination to obtain the proper
bearing setting.
(9) Use Tool L-4434 to remove the retaining nut
and washer. Remove the transfer shaft gear using
Tool L-4407.
(10) Remove the two gauging shims and install the
correct shim combination. Install the transfer gear
and bearing assembly.
(11) Install the retaining nut and washer and
torque to 271 N´m (200 ft. lbs.). Measure transfer
shaft end play, end play should be 0.05 to 0.25 mm
(0.002 to 0.010 inch).
(12) Measure bearing end play as outlined in Step
(4). End play should be between 0.05 mm and 0.25
mm (0.002 to 0.010 inch).
NOTE: If end play is too high, install a 0.05 mm
(0.002 inch) thinner shim combination. If end play is
too low, install a 0.05 mm (0.002 inch) thicker shim
combination. Repeat until 0.05 to 0.25 mm (0.002 to
0.010 inch) end play is obtained.
