VALVE HOUSING
Vinyl t.p.
Check the inner wall of the valve housing where the
seal ring slides with your finger. lf there is a step in
the wall, the valve housing is worn. Replace the
valve housing.
NOTE:
There may be the sliding marks from the seal
ring on the wall of the valve housing. Replace
the valve housing only the wall is stepped.
When the valve housing is replaced, install new
32 mm shim(s) on the bearing surface of the
housing to adjust the thickness.

Make the valve seal ringsnugly fit in the.pinionshaft using the other end(smaller diameter end) ofthe specialtool.

Apply power steering fluid to the surface of the spe-
cial tool. Set the new seal rings over the special tool
from the smaller diameter end of the tool, and
expand the seal rings. Do two rings at a time from
each end of the sleeve,
NOTE:
. 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.
Set the special tool in the grooves in the sleeve. and
set each ring in each groove securely.
NOTE: After installation, compress the seal rings
with your fingers temporarily.
