seal ring slides with your finger. If 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 if the wall is stepped.
• '96 - 98 model only; when the valve housing is
replaced, install new 44 mm shim(s) on the bear-
ing surface of the housing to adjust the thick-
ness.

edges of the grooves in the sleeve.
NOTE: The pinion shaft and sleeve are a precision
matched set. If either the pinion shaft or sleeve
must be replaced, replace both parts as a set.
29. Remove the snap ring and pinion shaft sleeve from
the pinion shaft.
30. Using a cutter or an equivalent tool, cut and remove
the five seal rings from the sleeve.
CAUTION: Be careful not to damage the edges of
the sleeve grooves and outer surface when remov-
ing the seal rings.
