to solines of the Dinion shaft.
VALVE HOUSING
Separate the valve housing from the pinion shafv
valve using a press.
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 these items during inspection:
o 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.
. When the valve housing is replaced, install new
shim{s) on the bearing surface of the housing to
adiust the thickness.
Check the inside ofvalve housingfor a step in the wall.

26. Check for wear, burrs and other damage to the
edges of the grooves in the sleeve.
NOTE: The pinion shaft and sleeve are a precision
