2. Check rotor shaft for carbon deposits.
3. Measure rotor shaft runout.
Runout (Total indicator reading):
Standard
0.056 - 0.127 mm (0.0022 - 0.0050 in)
4. Measure rotor shaft end play.
End play:
Standard
0.013 - 0.097 mm (0.0005 - 0.0038 in)
IDo not allow wheels to turn when axial play is being mea-
sured.

WARNING:
ISituate vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled down.
IFor safety during subsequent steps, the tension of wires
should be slackened against the engine.
IBefore removing front axle from transaxle, place safety
stands under designated front supporting points. Refer to
GI section for lifting points and towing.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG
or Eurofast.
CAUTION:
IWhen lifting engine, be careful not to strike adjacent parts,
especially accelerator wire casing, brake lines, and brake
master cylinder.
IAlways use engine slingers when hoisting the engine.
IWhen removing drive shaft, be careful not to damage tran-
saxle oil seal.
1. Remove engine undercovers and splash covers.
2. Remove front exhaust tube.
3. Disconnect lower water hose from radiator and drain coolant.
4. Drain transaxle oil.
5. Remove power steering mounting bolt. (See left.)
6. Drain coolant from cylinder head.
7. Disconnect water hoses and electrical wiring from radiator and
remove radiator.
8. Disconnect fuel tubes and vacuum tubes.
9. Release power steering belt adjusting nut and remove power
steering pump from engine.
Bind pump properly to the vehicle.
10. Remove A/C compressor.
11. Disconnect or remove electrical wiring where necessary.
12. Release clutch lever cable.
13. Release tachometer cable from transaxle housing.
14. Remove front wheels.
15. Remove brake caliper mounting bolts and bind caliper properly
to vehicle LH & RH.

2. Install pistons with connecting rods.
IInstall them into corresponding cylinder using Tool.
IBe careful not to scratch cylinder wall with connecting
rod.
IApply engine oil to cylinder wall, piston and bearing.
IArrange so that the front mark on piston head faces to the
front of engine.
3. Install connecting rod bearing caps.
IApply engine oil to the thread of connecting rod bearing
nut.
(1) Tighten connecting rod bearing nut to 15 1 N´m (1.5 0.1 kg-m,
10.8 0.7 ft-lb).
(2) Then tighten an additional 60
