the connecting rod as a set, so it must be replaced
together with the connecting rod as a
set.
4.
If a new crankshaft and/or connecting rod is
used,
select the proper bearing insert in accordance with
the combination table (Table F4) for the connect-
ing rod and the crankshaft marks (Figs. F55 and
F56)
.
If the crankshaft is not replaced, first measure
the diameter of connecting rod journal of the crank-
shaft.
Then mark its flywheel with the diameter (Pg.
187),
and select the proper bearing insert in accord-
ance with Table F4.
5.
The connecting rods are not symmertrical. Install

at the factory as an
assembly,
and must be replaced
together as a set.
2. When the crankcase halves are replaced, install the
original shims, check the clearance between the needle
thrust bearing and the crankcase and the bevel gear
backlash and tooth contact pattern. Adjust them if
necessary
(Pg.
115 and Pg. 112).
SHIM ADJUSTMENT
Backlash and Tooth Contact of Bevel Gears
Improper backlash and/or tooth contact of bevel
gears lead to noise and damage of
gears.
When replacing anyone of the following parts which
influence the backlash and tooth contact of bevel gears,
make sure to check and adjust them
.
First, adjust the
backlash of
gears,
and then get the correct tooth contact
pattern by replacing shims.
Parts which change the backlash and tooth contact
are:
