DRIVE BELTS
CheckingINFOID:0000000001381384
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 When checking immediately after installation, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

DRIVE BELTS
CAUTION:
 When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
 Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt.
CAUTION:
 When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
 When the tension adjustment is performed, the lock nut should be in the condition at step“2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
Removal and InstallationINFOID:0000000001381386
REMOVAL
1. Loosen the idler pulley lock nut (A), and then adjust the belt ten-
sion by turning the adjusting bolt (B).
2. Remove drive belt.
INSTALLATION
1. Pull the idler pulley in the loosening direction, and then tempo-
rarily tighten the idler pulley lock nut (A) to the following torque.
NOTE:
Do not move the lock nut from the tightened position. Proceed to step “2”.
2. Install the drive belt to each pulley.
CAUTION:
 Make sure that there is no oil, grease, or coolant, etc. in pulley grooves.
 Make sure that the belt is securely inside the groove on each pulley.
3. Adjust drive belt tension by turning the adjusting bolt. Refer to EM-15, "
Tension Adjustment".

REMOVAL
1. Remove camshafts. Refer to EM-59, "Exploded View".
2. Remove valve lifters. Refer to EM-59, "
Exploded View".
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve
from dropping into cylinder.
CAUTION:
When rotating crankshaft, be careful to avoid scarring front cover with timing chain.
4. Remove valve collet.
 Compress valve spring with the valve spring compressor, the
attachment and the adapter [SST: KV10116200] (A). Remove
valve collet with a magnet hand (B).
CAUTION:
Be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat. Refer to EM-82, "
Disassembly and
Assembly".
6. Remove valve oil seal with the valve oil seal puller [SST:
KV10107902] (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height “H” shown with the valve oil
seal drift [SST: KV10115600] (A).
3. Install in the reverse order of removal, for the rest of parts.

ENGINE ASSEMBLY
 If items or work required are not covered by the engine section, follow the procedures in the applica-
ble sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-48, "
Garage Jack and
Safety Stand and 2-Pole Lift".
