Caution
1. Before checking, turn the engine one time or more.
2.If the belt tension is too strong, it is possible that the
generator or water pump bearing is damaged.
If the b’elt tension is too weak, however, sounds of its
slipping will be heard, and the belt’s service life will be
reduced.
1.Loosen the generator pivot nut.
2. Loosen the lock bolt of the belt tension adjuster.
3. Using the adjustment bolt, adjust the belt tension to
specified.
4. Tighten the lock bolt.
5.Tighten the generator pivot nut.
6.Check the deflection or the tension of the belt; readjust if
necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been
used for as long as five minutes or more.
DEFLECTION ADJUSTMENT OF POWER STEERING OIL
PUMP DRIVE BELT
1. Loosen power steering oil pump fixing bolt.
2. Move power steering pump, tension belt moderately and adjust deflection.
3. Tighten fixing bolts.
4. Run the engine one time or more.
5. Check the belt deflection. Readjust, if necessary.
TENSION ADJUSTMENT OF THE AIR CONDITIONING
COMPRESSOR DRIVE BELT
1. Loosen tension pulley fixing bolt A.
2. Adjust belt deflection with adjusting bolt B.
3. Tighten fixing bolt A.
4. Run the engine one time or more. 5. Check the belt tension. Readjust, if necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been
used for as long as five minutes or more.

SERVICE POINTS OF REMOVAL
Ml 1SBBC
24. REMOVAL OF POWER STEERING OIL PUMP
Remove the oil pump (with the hose attached).
NOTE
Suspend the removed oil pump (by using wire or similar
material) at a place where no damage will be caused
during removal/installation of the engine assembly.
25. REMOVAL OF AIR CONDITIONING COMPRESSOR
Disconnect the
connection of the air conditioning compres-
sor, and then remove the compressor (with the hose at-
tached) from the compressor bracket.
NOTE
Suspend the removed air conditioning compressor (by using wire or similar material) at a place where no damage
will be caused during removal/installation of the engine as-
sembly.
29. REMOVAL OF ENGINE MOUNT BRACKET
(1) Attach wire or similar material to the engine hook, and then suspend (to the extent that there is no slackness
of the wire) by using a chain block or similar arrange-
ment.
(2) Remove the engine mount bracket.
31. REMOVAL OF ENGINE ASSEMBLY
(1) Check to be sure that all cables, hoses, harness connectors, etc. are disconnected from the engine.
(2) Lift the chain block slowly to remove the engine assembly upward from the engine compartment
.
