d. Bearing Preload Adjustment.
NOTE
Correct bearing preload is attained by
removing increments of shim pack. If bearing
cup bears on rollers, allowing no movement,
disassemble all bearing retention parts.
(1) Install dial indicator on output housing (1) with stylus on
output shaft (2).
(2) Adjust dial indicator to read zero.
(3) Apply upward lift sufficient to fully seat upper bearing (3).

•
Dial indicator reading at this point is preliminary
end play which exists with initial shim pack
thickness of 0.064 in. (0.162 cm).
•
If reading is not within tolerance, disassemble
rear output housing. Replace shims to achieve
correct end play and assemble rear output
housing.
(4) Measure end play of output shaft (2). Reading should
be 0.001-0.005 in. (0.003-0.013 cm). Record reading.
