Attach backlash measuring tool clamp e to drive shaft.
Turn drive shaft w clockwise / counterclockwise slowly
while pulling it up, and read change of dial gauge
indication.
When measuring, contact dial gauge tip to inside
of V groove located in the clamp ass'y.

Select shim thickness required based on the change of
dial gauge indication and the table shown.
· Confirm dial gauge reading and adjust backlash
by using thickness of shim selected.
· Measure backlash several times while changing
gear teeth contact position.
· When measuring backlash, make drive shaft
pulling up force equal among the measurements.
· This work can be made easier when the opening
of gear case of propeller shaft side is faced
upward and fixed horizontally with a holder.
Proper Backlash :
0.29 - 0.58 mm (0.0114 - 0.0228 in)
Add shim(s) into gap b between reverse (C) gear t and
bearing y if necessary.
CAUTION
For removal or installation of reverse (C)
gear, refer to;
"Disassembly of Propeller Shaft Housing
Ass'y" or "Assembly of Lower Unit" in
Chapter 6 respectively.
