Alternator and Fan Drive Belts
Inspect/Adjust/Replace
Your engine will be equipped with a water pump belt and a pair of belts for the fan drive and alternator. Inspect the condition and adjustment of alternator and fan drive belts. Inspect all drive belts and replace if they show any signs of wear.Check and adjust the belt tension to minimize belt slippage. If belts are too loose, they vibrate enough to cause unnecessary wear on the belts and pulleys. If belts are too tight, unnecessary stresses are placed upon the pulley bearings and belts which might shorten the life of both.To Adjust Drive Belt
The alternator is used for tension adjustment. Correctly adjusted belts will deflect approximately 9 to 15 mm (3/8 to 5/8 inch). If new belt(s) are installed, check belt adjustment again after 30 minutes of operation.To adjust the belt tension, loosen the alternator bolts and slide the alternator in the desired direction to increase or decrease the belt tension. 1. To adjust the alternator drive belt, loosen mounting bolt (1) and the adjusting bracket bolt (2).2. Move the alternator in or out as required to obtain the correct adjustment. Tighten the bolts (1) and (2). Do not overtighten.3. If new belts are installed, check belt adjustment again after 30 minutes of engine operation.To Adjust Water Pump Belt
1. To adjust the water pump drive belt, loosen mounting bolt and bracket bolt.2. Move water pump idler pulley in or out as required to obtain the correct adjustment.3. To make the correct adjustment, use the square hole in the mounting bracket or bolt to apply tension.4. Tighten bolts. Do not overtighten. The water pump belt is not used to drive any other accessories. Excessive tightening can damage the water pump bearings or shaft.5. If a new belt is installed, check the belt adjustment again after 30 minutes of engine operation at rated speed.Fan Drive Bearing
Lubricate
Lubricate one fitting with Caterpillar 2S3230 SPG grease. Refer to the Lubrication Specifications section in this Manual for the proper lubricating grease to be used.Inspect the fan drive pulley assembly. It should be difficult to detect movement of the shaft in the bearing. If the shaft is loose in the bearings, an inspection of the internal components should be made.The bearing end play should be 0.03 to 0.23 mm (.001 to .009 inch). The radial play should be no greater than 0.13 mm (.005 inch). Fan Clutch-For emergency operation or electrical override, use one M6 x 1 cap screw inserted in fan spider clearance holes to allow continuous operation of fan. Have fan clutch repaired at next stop.
Do NOT operate engine with this condition for long periods of time because an engine over cooling problem (low operating temperatures) will cause sludge formation and excessive carbon build-up on critical engine components.
If the assembly should require disassembly, refer to the Service Manual for the procedure.Battery
