●
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.
