DRIVE BELTSPFP:02117
Checking Drive BeltsNBS004MU
WAR NING :
Be sure to perform when 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 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 the 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 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 the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.
Tension AdjustmentNBS004MV
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 crankshaft two turns or more, re-adjust to the specified value to
avoid variation in deflection between pulleys.
When installing belt, make sure that it is correctly engaged with pulley grooves.
Keep engine oil, working fluid and engine coolant away from belt and pulley grooves.
Do not twist or bend belt excessively.
