●

As for bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.

●

Within 5 minutes of liquid gasket application, install the mating
component.

●

If liquid gasket protrudes, wipe it off immediately.

●

Do not retighten mounting bolts or nuts after the installation.

●

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.

CAUTION:

If there are specific instructions in this manual, observe
them.

DRIVE BELTS

PFP:02117

Checking Drive Belts

NBS00298

WARNING:

Be sure to perform when the engine is stopped.
1.

Inspect belts for cracks, fraying, wear and oil. If necessary, replace.

2.

Inspect drive belt deflection or tension at a point on belt midway
between pulleys.

●

Inspection should be done only when the engine is cold, or
over 30 minutes after engine is stopped.

●

Measure the belt tension with belt tension gauge (commercial
service tool: BT3373-F or equivalent) at points marked 
shown in the figure.

●

When measuring deflection, apply 98 N (10 kg, 22 lb) at the 
marked point.

●

Adjust if the belt deflection exceeds the limit or if the belt ten-
sion is not within specifications.

CAUTION:

●

When checking the belt deflection or the tension immediately after installation, first adjust it to
the specified value. Then, after turning the crankshaft two turns or more, re-adjust to the speci-
fied value to avoid variation in deflection between pulleys.

●

Release the tension by loosing lock nut and turning
adjusting bolt when adjusting the belt. Tighten once the
lock nut at 4.9 N·m(0.50 Kg-m,43 in-lb). Then, adjust the
belt tension by loosing lock nut between 45

°

 and 90

°

. 

Belt Deflection and Tension

*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on the belt.

Tension Adjustment

NBS00299

CAUTION:

●

When belt is replaced with a new one, adjust it to value for “New belt” to accommodate for insuffi-
cient adaptability with pulley grooves.

●

When deflection or tension of belt being used exceeds “Limit”, adjust it to value for “After adjust-
ment”.

●

When checking belt deflection or tension immediately after installation, first adjust it to the speci-
fied value. Then, after turning the crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.

●

Release the tension by loosing lock nut and turning adjusting nut when adjusting the belt. Tighten
once the lock nut at 4.9 N·m (0.50 kg-m,43 in-lb). Then, adjust the belt tension by loosing lock nut
between 45

°

 and 90

°

.

●

When installing belt, make sure that it is correctly engaged with pulley groove.

●

Keep engine oil, working fluid and engine coolant away from belt.

●

Do not twist or bend belt excessively.
