(4) Overrunning clutch
Make sure that the pinion shaft tums freely when
tumed in the direction of driving (clockwise) and
it is locked when tumed in the opposite direction.
If not, replace the overrunning clutch.
(5) Pinion shaft thrust clearance
The pinion shaft thrust clearance is the play
exhibited by the pinion shaft when it is moved in
the thrust direction.
Measure the thrust clearance in the following
manner. If it is incorrect, select a proper adjusting
washer and adjust the clearance with the washer.
(a) With pinion off starter:
Install the gear on the pinion shaft, insert the
shaft into the center bracket, and loek the shaft
with the washer and ring. Under this
condition, move the shaft in the axial
direction, and measure the thrust clearance.
(b) With pinion on starter:
Install the pinion shaft and gear between the
front and center brackets, and temporarily
tighten the bolt. Under this condition, move
the shaft in the axial direction, and measure
the thrust clearance.
