CAUTION:
Apply new engine oil to parts marked in illustration before installation.
DISASSEMBLY
1. Remove engine assembly from the vehicle, then separate engine and transaxle. Refer to EM-193,
"ENGINE ASSEMBLY" .
2. Remove clutch cover and disk. Refer to CL-15, "
CLUTCH DISC,
CLUTCH COVER AND FLYWHEEL" .
3. If they need to be replaced, replace pilot bushing.
●Using pilot bushing puller, remove the bushing from rear edge
of crankshaft.
4. Install engine to engine stand as follows.
a. Remove flywheel.
b. Secure ring gear with ring gear stopper, then loosen mounting
bolts with TORX bit (size: Q6T55 E9, Commercial Service Tools)
and remove them. As an alternative method hold the crankshaft
pulley with a pulley holder (SST) to remove the flywheel.
CAUTION:
Do not disassemble flywheel.
c. Install engine sub-attachment to the rear side of cylinder block.
●Align knock pins on cylinder block with pin holes on attach-
ment to install.
NOTE:
Installation bolts are part of engine sub-attachment.
d. Install engine attachment.
NOTE:
Use commercially available M12 (0.47 in) mounting bolts and
nuts (4 sets) with strength grade of 9T (minimum).

17. Install rear oil seal and retainer assembly.
●Apply a continuous bead of liquid gasket to rear oil seal and
retainer assembly as shown in the figure.
18. Press fit pilot bushing into flywheel.
●Using drift with outer diameter of 19 mm (0.75 in), press fit
pilot bushing until it stops.
19. Install fuel supply pump bracket.
●Align the bracket with the dowel pins on the block to install.
●The two bolts used for dowel pins have a longer shanks than
the other two.
20. Install parts to the engine in the reverse order of disassembly.
21. Remove engine from engine stand in the reverse order of
assembly.
22. Install flywheel.
●When installing flywheel to crankshaft, be sure to correctly
align crankshaft side dowel pin and flywheel side dowel pin-
hole.

OIL JET
●Check nozzle for deformation and damage.
●Blow compressed air from nozzle, and check for clogs.
●If it out of the standard, replace oil jet.
OIL JET RELIEF VALVE
●Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.
●If it is out of the standard, replace oil jet relief valve.
MOVEMENT AMOUNT OF FLYWHEEL
NOTE:
●Inspection for double mass flywheel only.
●Do not disassembly double mass flywheel.
Flywheel Deflection
●Measure deflection of flywheel contact surface to the clutch with a dial gauge.
●Measure deflection at 210 mm (8.27 in) dia.
●When measured value exceeds the limit, replace flywheel with a
new one.
Movement Amount in Radial (rotation) Direction
Check the movement amount in the following procedure.
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.
●Tighten bolt at a force of 9.8 N·m (1 kg-m, 87 in-lb) to keep it from loosening. Standard : Deformation and damage.
JEM221G
Standard:
Valve moves smoothly with proper reaction force.

2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1 kg-m, 87 in-lb) in each direction, and
mark the movement amount on the mass on the transaxle side.
4. Measure dimensions of movement amounts A and B on circum-
ference of the flywheel on the transaxle side.
●When measured value is outside the standard, replace fly-
wheel.Standard : 26.2 mm (1.031 in) or less

WARNING:
Be careful not to get burned when the engine and engine oil are hot.
CAUTION:
●When removing oil cooler, prepare a shop cloth to absorb any engine oil leakage or spillage.
●Completely wipe off any engine oil that adhere to the engine and the vehicle.
REMOVAL
1. Remove front RH wheel and engine room right side cover.
2. Drain engine coolant by removing cylinder block drain plug and radiator drain cock. Refer to CO-9,
"Changing Engine Coolant" .
3. Paint a mating mark at the oil cooler and oil cooler bracket.
INSPECTION
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Oil Pressure Relief Valve
Inspect oil pressure relief valve for movement, cracks and breaks by pushing the ball. If replacement is neces-
sary, remove valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is in the reverse order of removal.
●After warming up the engine, check for engine oil and engine coolant leakage and for engine oil level.
Refer to LU-7, "
ENGINE OIL" .
