5. REMOVE PISTON RING SET
(a) Using a piston ring expander, remove the 2 compression
rings.
(b) Remove the 2 side rails and oil ring by hand.
6. REMOVE PISTON
(a) Using a small screwdriver, pry out the 2 snap rings.
(b) Gradually heat the piston to 80 to 90 C (176 to 194 F).
(c) Using a plastic±faced hammer and brass bar, lightly tap
out the piston pin and remove the connecting rod.
HINT:
The piston and pin are a matched set.
Store the pistons, pins, rings, connecting rods and bear-
ings in correct order so that they can be returned to the
original locations when re±assembling.
7. INSPECT CRANKSHAFT THRUST CLEARANCE
(a) Using a dial indicator, measure the thrust clearance while
prying the crankshaft back and forth with a screwdriver.
Standard thrust clearance:
0.040 to 0.240 mm (0.0016 to 0.0094 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)
(b) If the thrust clearance is greater than maximum, replace
the thrust washers as a set.
Thrust washer thickness:
1.930 to 1.980 mm (0.0760 to 0.0780 in.)

(b) Using a screwdriver, pry out the stator sub±assy genera-
tor w/rectifire.
4. REMOVE BEARING SET GENERATOR
5. REMOVE PULLEY SET GENERATOR
(a) Clamp the swivel arm in a vise.
NOTICE:
Be careful not to damage the fan.
(b) Using an impact wrench or internal serration on rotor shaft
end together with a torque wrench,remove the nut and
spring washer, then detach the pulley.
6. REMOVE GENERATOR ROTOR ASSY
(a) Using a press, press out the generator rotor assy and
spacer ring.
7. INSPECT GENERATOR ROTOR ASSY
(a) Inspect the generator rotor assy for open circuit.
(1) Using an ohmmeter, check that there is continuity
between the slip rings.
Standard resistance: 2.27 to 2.53 at 20C (68F)
If there is no continuity, replace the generator rotor assy.
(b) Inspect the generator rotor assy for ground.
(1) Using an ohmmeter, check that there is no continu-
ity between the slip ring and the generator rotor
assy.
If there is continuity, replace the generator rotor assy.
