Overrunning Clutch Assembly; Pinion Gear Clearance; Pinion Case Bearing; Measuring Pinion Edge-To-Pinion Stopper Clearance - Mazda 1983 RX7 Service Manual

Overrunning Clutch Assembly

1) Inspect pinion assembly and sleeve. Sleeve should slide
freely on armature shaft and spline. If damage or resistance is
noted, replace assembly.
2) Check pinion and flywheel teeth for excessive rubbing or
damaged teeth. Replace as required.

Pinion Gear Clearance

1) The clearance between the pinion gear and pinion stopper
collar should be .012-.098" (.3-2.5 mm) on Hitachi starters, or
.02-.08" (.51-2.03 mm) on Mitsubishi starters, when solenoid is
engaged. Adjust as necessary by changing shims between solenoid and
starter yoke.
2) On Mazda B2200 models, projection distance (starter
housing-to-front face of gear) should be .67" (17 mm). On Mazda RX-7
models, projection should be 1.06" (27.5 mm).

Pinion Case Bearing

Inspect bearing for wear and check side play. If clearance
exceeds .008" (.2 mm), replace bearing. New bearing clearance should
be .001-.004" (.025-.10 mm) for Hitachi or .002-.004" (.05-.10 mm)
for Mitsubishi starters.
NOTE: Ensure that bearing is installed so that end of bearing is
flush with gear case end.
REASSEMBLY
To reassemble, reverse disassembly procedure. Fill gear case
on reduction gear models with grease. Lightly oil pinion and all
bearing surfaces.
