Check and Adjust Accessory/Drive Belt
Check
Check the accessory/drive belt condition.
1. Per
form visual inspection as follows:
• Inspect belt for cracks, fraying, excessive wear or
other damage.
• Verify belt is free of grease and oil.
• Replace belt if contaminated, damaged, frayed or
worn.
NOTE: Use
a solution of soap and warm water to clean
pulleys, if necessary. Avoid use of solvents, but if used,
always follow by a soap and water wash.
2. Che
ck the fan belt deflection. Adjust the belt
deflection as follows:
• Using a suitable gauge, apply 22 Ibs (10 kgf) force
midway between the water pump and alternator
pulleys. See Figure 5-11.
NOTE: 5
.4L (48 kW) units are provided with an
automatic belt tensioner and do not need adjustment.
• Take note of gauge reading. If belt deflection is not
within specification, see Adjust.
Belt Deflection
English Metric
3/8 - 5/8 in 7.6 - 12.7 mm
Adjust
1. Loosen DC alternator tension bracket screw.
Rotate alternator outward to reduce belt deflection,
rotate inward to increase belt deflection.
2. T
ighten DC alternator tension bracket screw to 17-
22 ft-lbs (23-30 Nm).
3. Reche
ck belt deflection and repeat steps as
necessary.
