4. REMOVE STARTER ARMATURE PLATE
(a) Remove the armature plate from the starter yoke.
5. REMOVE STARTER BRUSH HOLDER ASSY
(a) Remove the 2 screws and brush holder assy from the
commutator end frame.
6. REMOVE PLANET GEAR
(a) Remove the 3 planet gears from the repair service starter
kit.
7. INSPECT REPAIR SERVICE STARTER KIT
(a) Check the plunger.
(1) Push in the plunger and check that it returns quickly
to its original position.
If necessary, replace the repair service starter kit.
(b) Check the pull±in coil for open circuit.
(1) Using an ohmmeter, check that there is continuity
between terminals 50 and C.
If there is no continuity, replace the repair service starter kit.

(c) Check if the hold±in coil has an open circuit.
(1) Using an ohmmeter, check that there is continuity
between terminal 50 and the switch body.
If there is no continuity, replace the repair service kit.
8. INSPECT STARTER ARMATURE ASSY
(a) Check the commutator for open circuit.
(1) Using an ohmmeter, check that there is continuity
between the segments of the commutator.
If there is no continuity between any segments, replace the ar-
mature.
(b) Check the commutator for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between the commutator and the armature coil
core.
If there is continuity, replace the armature.
(c) Check the commutator for dirty or burned surface.
If the surface is dirty or burnt, smooth the surface with 400±grit
sandpaper.
(d) Check for the commutator circuit runout.
(1) Place the commutator on V±blocks.
(2) Using a dial indicator, measure the circle runout.
Standard runout: 0.02 mm (0.0008 in.)
Maximum runout: 0.05 mm (0.0020 in.)
If the runout is greater than maximum, replace the armature.
(e) Using vernier calipers, measure the commutator diame-
ter.
Standard length: 29 mm (1.142 in.)
Minimum length: 28 mm (1.102 in.)
If the diameter is less than minimum, replace the armature.

2. REMOVE OIL PUMP RELIEF VALVE SPRING
3. REMOVE OIL PUMP RELIEF VALVE
4. INSPECT OIL PUMP RELIEF VALVE
(a) Coat the oil pump relief valve with engine oil.
(b) Check that it falls smoothly into the oil pump relief valve
hole by its own weight.
If it does not, replace the oil pump relief valve.
If necessary, replace the oil pump assembly.
5. REMOVE OIL PUMP COVER
(a) Remove 7 bolts and the oil pump cover.
6. INSPECT OIL PUMP ROTOR SET
(a) Place the drive and driven rotors into the oil pump body
with the marks facing the oil pump cover.
7. INSPECT ROTOR TIP CLEARANCE
(a) Using a feeler gauge, measure the clearance between
the drive and driven rotor tip.
Standard tip clearance:
0.080 to 0.160 mm (0.0031 to 0.0063 in.)
Maximum tip clearance: 0.35 mm (0.0138 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.

8. INSPECT ROTOR BODY CLEARANCE
(a) Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance:
0.100 to 0.170 mm (0.0039 to 0.067 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
9. INSPECT ROTOR SIDE CLEARANCE
(a) Using a feeler gauge and precision straight edge, mea-
sure the clearance between the rotors and precision
straight edge.
Standard side clearance:
0.030 to 0.085 mm (0.0012 to 0.0033 in.)
Maximum side clearance: 0.16 mm (0.0063 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
10. REMOVE OIL PUMP ROTOR SET
