Lock boltTENSION ADJUSTMENT OF THE GENERATOR DRIVE
BELT
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 belt tension is too weak, however, sounds of its slip-
ping 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.

32. DISCONNECTION OF POWER STEERING OIL PUMP Disconnect the oil pump with hoses from the bracket.
NOTE
The removed power steering oil pump should be fastened(by using rope, etc.) in a position that will not interfere
with the removal/installation of the engine assembly.
33. DISCONNECTION OF AIR CONDITIONING COMPRESSOR
Disconnect air conditioning compressor connector and re-
move it with hoses from the compressor bracket.
NOTE
The removed air conditioning compressor should be fas-
tened (by using rope, etc.) in a position that will not inter-
fere with the removal/installation of the engine assembly. OlA0177
37. DISCONNECTION OF ENGINE MOUNT BRACKETBefore removing the engine mount bracket installation
bolt, use a chain block or similar arrangement to suspend
the engine assembly (to the extent that there is no
looseness of the chain).
