TIP:
• The gray-colored cells on the selection
table indicate the range where the shim
adjustment is unnecessary. Shimming is
not required if the obtained forward gear
shim thickness is indicated by the gray-col-
ored cells.
• The values for the shim thickness specified
in the selection table are intended to obtain
the median value within the range for the
specified forward gear backlash.
• If the backlash measurement (BL1) is less
than 0.18 mm, install a new shim with a
thickness of 2.00 mm.
• If the backlash measurement (BL1) is more
than 0.44 mm, install a new shim with a
thickness of 2.15 mm.
• Use only 1 shim to obtain the required shim
thickness.
6. Install the adapter, determined forward
gear shim (T1), thrust bearing, and
forward gear. See “Installing the forward
gear” (8-28).
Available shim thicknesses:
2.00, 2.03, 2.06, 2.09, 2.12, 2.15 mm
