Tension Adjustment
EBS00LPZ
CAUTION:
●When belt is replaced with a new one, tighten it a little
stronger than current one to accommodate for insufficient
adaptability with pulley grooves.
●When tension of belt being used exceeds “Retightening
limit”, adjust it to value for “Used belt”.
●When installing belt, make sure that it is correctly engaged with pulley groove.
●Keep oil and water away from belt.
●Do not twist or bend belt excessively.
●When adjusting belt, remove snap retainer from adjusting bolt thread (to prevent the retainer from
becoming pinched or missing).
●After adjustment, be sure to install snap retainer to adjusting bolt thread.
NOTE:
Snap retainer can prevent adjusting bolt from dropping due to vibration during driving.
POWER STEERING PUMP AND WATER PUMP BELT
1. Loosen lock nut (A) and power steering pump mounting nut (B).
2. Turn adjusting bolt (C) to adjust. Refer to EM-11, "
Checking
Drive Belts" .
3. Tighten lock nut (A) and power steering pump mounting nut (B)
in this order.
ALTERNATOR AND AIR CONDITIONER COMPRESSOR BELT
1. Remove RH splash cover (with undercover attached).
2. Loosen lock nut (G).
3. Turn adjusting bolt (H) to adjust.
Refer to EM-11, "
Checking Drive Belts" .
4. Tighten lock nut (G).

4. Install oil pump drive spacer.
●When installing, align with flat of oil pump inner rotor.
●If they are not aligned, rotate inner rotor with a flat-bladed
screwdriver to align them.
CAUTION:
Be careful not to damage oil seal lips.
5. Install water pump pulley and idler pulley bracket assembly.
6. Install crankshaft pulley.
●When installing it, make sure that front oil seal lip is not inverted and garter spring is in position.
●For direction of mounting bolt washer, refer to “Component Parts Location”.
●With same procedure as “removal”, secure crankshaft, and tighten mounting bolts.
7. Install cylinder head front cover.
●Apply liquid gasket to cylinder head front cover.
●Use Genuine Liquid Gasket or equivalent.
8. Install engine front mounting bracket.
9. Install remaining parts in the reverse order of removal.
INSPECTION AFTER INSTALLATION
●In order to allow liquid gasket to be cured, perform inspection at least 30 minutes after the last step in
which parts sealed with liquid gasket are installed.
●With engine warmed up, check each part for engine oil leakage.

InspectionNJEM0088Before inspecting the engine, make sure the engine has
cooled down; wait approximately 30 minutes after the engine
has been stopped.
Visually inspect all belts for wear, damage, or cracks on con-
tacting surfaces and edge areas.
When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.
When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning the crankshaft two turns or more, re-adjust to
the specified value to avoid variation in deflection
between pulleys.
Tighten idler pulley lock nut by hand and measure deflec-
tion without looseness.

CAUTION:
When a new belt is installed as a replacement, adjust it to
the value specified under “New” accommodations
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit
for re-tightening”, adjust to the “Adjusted value”.
When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning crankshaft two turns or more, re-adjust it to
the specified value to avoid variation in deflection
between pulleys.
Make sure the belts are fully fitted into the pulley grooves
during installation.
Handle with care to avoid smearing the belts with oil or
cooling water etc.
Do not twist or bend the belts with strong force.
