Caterpillar Generator C32

Always recycle a battery. Never discard a battery.

Always return used batteries to one of the following locations:

• An authorized battery collection facility

Check the battery charger for proper operation. If the batteries are properly charged, the needle of the ammeter will register near “0” (zero).

Cooling System Water Temperature Regulator - Replace

Replace the water temperature regulator before the water temperature regulator fails. This is a recommended preventive maintenance practice. Replacing the water temperature regulator reduces the chances for unscheduled downtime.

A water temperature regulator that fails in a partially opened position can cause overheating or overcooling of the engine.

A water temperature regulator that fails in the closed position can cause excessive overheating. Excessive overheating could result in cracking of the cylinder head or piston seizure problems.

A water temperature regulator that fails in the open position will cause the engine operating temperature to be too low during partial load operation. Low engine operating temperatures during partial loads could cause an excessive carbon buildup inside the cylinders. This excessive carbon buildup could result in an accelerated wear of the piston rings and wear of the cylinder liner.

Failure to replace your water temperature regulator on a regularly scheduled basis could cause severe engine damage.

Caterpillar engines incorporate a shunt design cooling system and require operating the engine with a water temperature regulator installed.

If the water temperature regulator is installed incorrectly, the engine may overheat, causing cylinder head damage. Ensure that the new water temperature regulator is installed in the original position. Ensure that the water temperature regulator vent hole is open.

Inspect the alternator belt and the fan drive belts for wear and for cracking. Replace the belts if the belts are not in good condition.

Check the belt tension according to the information in the Service Manual, “Specifications”.

Slippage of loose belts can reduce the efficiency of the driven components. Vibration of loose belts can cause unnecessary wear on the following components:

If the belts are too tight, unnecessary stress is placed on the components. This reduces the service life of the components.

Engine Crankcase Breather - Clean

The crankcase breather is located on the back of the engine.

1. Remove the tube (2) from the outlet of the breather and loosen the clamp.

2. Remove the bolts (1) and remove the breather from the engine.

3. Check the condition of the seal. Replace the seal if the seal is damaged.

4. Remove the breather element. Wash the breather element and wash the breather in a clean nonflammable solvent.

5. Shake the breather element until the breather element is dry. You may also use pressurized air in order to dry the breather element.

6. Check the condition of the tube. Replace the tube if the tube is damaged.

7. Install the element into the breather and install the breather.
