from the smaller diameter end of the tool. and
expand the seal rings. Install two rings at a time
Jrom each end ofthe sleeve.
Note these items when installing the seal ring:
. Do not over-expand the seal ring. Install the resin
seal rings with care so as not to damage them.
After installation, be sure to contract the seal
rings using the specialtool {sizing tool).
. There are two types of sleeve seal rings: black
and brown. Do not mix the different types of
sleeve seal rings as they are not compatible.
Align the special tool with each groove in the sleeve,
and slide a sleeve seal ring into each groove. After
installation, compress the seal rings with your fin-
gers temporarily.

Shim selection:
Set the four 32 mm shims on the bearing surface of the
gearbox housing. Total thickness of the four shims
should equal no more than 0.70 mm.
