29. Assemble the valve sleeve (5b) with attached thrust
washer down into the valve housing (19) (figure 11-80).
30. Measure height of valve sleeve to face of valve housing
(figure 11-81}; should be .370-.400" (.929-1.01 cm}. If not as
required, repeat steps 25 thru 33.
WARNING: Do not force valve sleeve down
Into valve housing. Make sure valve sleeve
seal rings are comprened. Mlsassembly or
incorrect measurement may cause the
thrust washers or thrust bearing to break
during gear operation, which will result in
uncontrollable steering.

31. Position the rack piston (10) so that it is flush with the
open end of the gear housing
{1 ).
Rotate the worm shaft (Sa)
until it extends out of the rack piston as far as it will go.
WARNING: Worm shaft and valve sleeve
units
■ re m■nutactuntd
and

sets. Use only prematched
Hts
tor replace-
ment. Never mate an old slNve with a new
worm or an old worm with a new sl•ve. To
do so may damage the gear or Injure the
driver, or both during operation.

lead (which wlll come out of the rack piston
when tumlkl clockwlse), the valve spool
has no Identifying mark between the lands.
WARNING: If an Incorrect valve spool Is
placed on a worm and .... mbled Into the
gear, the gear wlll malfunction by turning
the steering wheel with such force that It
could Injure the driver.
