Checking Clutch Adjustment
While engaging the clutch to pick up the load, check the clutch adjustment. The clutch should engage with a hard push and distinct snap. If engagement is "soft", adjust the clutch.Adjusting Clutch
1. Stop the engine and remove the clutch inspection cover.
CLUTCH INSPECTION COVER2. Turn the clutch until the lock pin, engaged in the locking ring, is visible.3. Pull the lock pin out and rotate the locking ring clockwise until the lock pin pops into the next notch.
LOCKING PIN4. Test the clutch adjustment. If still too "soft", rotate the ring to the next notch. If the adjustment is too tight-turn the ring back one notch.5. Install the cover.Lubricating Flywheel Clutches And/Or Front Power Take-Off Clutches
Lubricate the clutch bearings with grease, 1 or 2 strokes each fitting.1. Lubricate the shift lever bearings; 1 fitting on each side of the clutch housing.
PILOT, SHIFT COLLAR AND SHAFT BEARINGS2. Lubricate pilot bearing; 1 fitting at the end of shaft. If this fitting is not accessible, remove the plug located on the circumference of the shaft near the rear of the housing, and install a fitting.3. Lubricate the shift-collar bearings sparingly; 1 fitting at top left of center.4. D330-D333 - Lubricate the main shaft bearing; 1 fitting located above the output shaft on the bearing cage.
OIL FILLER TUBE AND BREATHER5. D334-D336 - Check the main shaft bearing oil reservoir level with engine stopped. Maintain the oil level at the FULL mark on the oil level gauge. Add oil through the filler tube on top of the bearing cage housing. See the Lubrication and Maintenance chart for proper oil.6. To drain the reservoir: Remove the drain plug located on the lower right side of the shaft bearing reservoir.7. Install the drain plug and fill reservoir to the FULL mark on the oil level gauge. Install filler cap.Electric Set Generator
Inspecting Slip Ring
1. Remove the two lower panels from the rear of the generator housing.2. Inspect the slip ring color. The slip ring color may be shiny copper to straw, or chocolate to black, but the color must be uniform to indicate satisfactory operation.If the ring is basically one of the above shades, but contains blotches of green, blue or black, clean the ring with an electrical cleaning solvent.
Do not use gasoline or carbon tetrachloride. Both solvents will dissolve insulation. The vapors from carbon tetrachloride can be harmful when inhaled.
Green blotches are caused by chlorine vapors, blue blotches are caused by sulphuric fumes, black blotches are caused by oil.3. Inspect the slip ring for pitting. If the slip rings are rough, pitted, or worn eccentric, contact your Caterpillar dealer. The rings must be reconditioned.4. Check the following to determine the cause for pitting: A. Check the generator nameplate rating. The generator load must be within this rating.B. Check the brush tension.Inspecting Brushes
The brush must move freely within the holder, but with enough spring tension to prevent brush flotation during operation.
CHECKING BRUSH SPRING TENSIONIf brush tension is weak, push the spring forward into the next notch. If the spring is in the front notch, remove the brush and check the brush length. If the brush length is less than the minimum required, install a new brush. If the spring is moved forward and the brush tension is greater than chart specifications, release the spring one notch. Excessive spring tension will cause excessive brush wear.Installing New Brushes
1. Release spring tension.2. Disconnect the lead wire from the brush and pull the brush from the brush holder.3. Insert a new brush. Be sure it moves freely in the brush holder. Connect the lead wire.4. Place a narrow piece of "00" sandpaper between the brush and slip ring with the abrasive surface against the brush. (Never use emery cloth as the emery contains small metallic particles which will damage the copper.)5. Engage the spring in the middle notch.6. Slowly pull the sandpaper from beneath the brush.7. Remove all dust with a suction hose. If suction is not available, use a very low pressure blower. Do not use metal hose tips.8. Check brush tension.9. Install the two panels.Lubricating The Rear Bearing
1. Remove the two lower panels from the rear of the generator housing.2. Remove the upper and lower grease fitting plugs.3. Install the grease fitting in the upper threaded hole.4. Lubricate with grease until clean lubricant appears at the lower threaded hole.
LUBRICATION PLUGS5. Wipe off the excess grease. Install the lower plug.6. Remove the fitting from the upper threaded hole.7. Start the engine and allow the grease to expand from the upper hole.8. Stop the engine. Install the plug in the upper hole and wipe off excess grease.9. Install the two panels.Marine Gear
Checking Oil Level
1. Check the oil level with the engine warm, idling, and the clutch engaged.
CHECKING OIL LEVEL2. Maintain oil level at the FULL mark on the oil level gauge. Add oil through the breather tube on top of the marine gear housing. Refer to Lubrication and Maintenance Chart for proper oil to use.
ADDING OILDraining Lubricating Oil
1. Remove the marine gear drain plug.
REMOVING DRAIN PLUGIf a sump pump is used:a. Connect a drain line to the top outlet of the sump pump.
SUMP PUMP VALVESb. Be sure the valve on the engine oil pan line is closed. Marks on the valve must be turned at right angles to the direction of the oil line.c. Open the valve on the marine gear oil line.d. Operate the sump pump handle until the oil is drained.Changing Oil Filter Element (509 & 513)
1. Drain the lubricating oil.2. Remove the bolts or nuts and remove the cover and filter element. Remove the element.
REMOVING COVER AND FILTER ELEMENT (509)3. Wash the inside of the housing and the cover.4. Inspect and install the cover gasket; install a new gasket if necessary.5. Install new element on cover and install cover and element assembly.
REMOVING COVER AND FILTER ELEMENT (513)Cleaning Oil Strainer (506)
1. Remove hose from pump inlet and loosen strainer retaining nut.2. Remove strainer from housing.
REMOVING STRAINER3. Wash the strainer in clean kerosene or diesel fuel.4. Inspect the strainer.
