TRANSMISSION OUTPUT GEAR BACKLASH INSPECTION/
ADJUSTMENT
13. The following steps must be performed to obtain
proper front output gear backlash adjustment:
S The pinion gear must be held securely.
S Do notlubricatethegear teethuntilbacklashad-
justmentiscomplete. BothGearsshouldbefree
of grease and oil.
S Perform adjustment with front output housing
seal removed and end play properly adjusted.
S Measure backlash using tool (PN 2871695).
The measurement point is 3.875″ (98.43mm)
from shaft centerline.
S Set backlash at .008″ - .014″ (.20 -.36mm).
S Checkbacklashinseverallocations ofringgear.
14. Install special tool (PN 2871695) on shaft as shown.
With pinion gear held stationary, rotate output shaft
back and forth, reading the total movement of dial
indicator. The dial indicator must be positioned as
shown at the proper distance (aligned with
outermost mark on tool, and 90° to the toolsurface),
or indicated backlash will be inaccurate.
S Toreducebacklash, rotatehousingclockwiseas
viewed from front of housing.
S To increase backlash, rotate housing counter-
clockwise.
15. Torque pinch bolts to specification. Be sure pinch
plate (A) is installed. Verify backlash measurement.
