SHIFT LEVER BEARING2. Lubricate the 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.
PILOT AND SHIFT COLLAR BEARINGS3. Lubricate the shift-collar bearing; 1 fitting at top-left of center.4. 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. Refer to Lubrication and Maintenance Chart for proper oil.
CHECKING OIL LEVEL5. To drain the reservoir: Remove the drain plug located on the lower left side of the shaft bearing reservoir. Drain and install the drain plug. Fill to the FULL mark on the oil level gauge. Install the filler cap.
CLUTCH SHAFT BEARING DRAIN PLUGElectric Set Generator
There are two types of Generators: SR4 and SRCR. To determine which generator you have, see the serial number stamped on the generator nameplate. The first group of numbers will be followed by either a "B", or a "T"; "B" designates a SR4 Generator, "T" designates a SRCR Generator. For a complete explanation of the serial number, see the ELECTRIC SET OPERATION INSTRUCTIONS.The SR4 Generator is a brushless type generator. The SRCR Generator uses slip rings and brushes. Periodically inspect the brushes and/or slip rings for wear and appearance.If the electric set generator is not of Caterpillar design, see the manufacturer's instructions for the required lubrication and maintenance procedures.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.
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 brush tension (SRCR Generators only).Inspecting Brushes (SRCR Generators Only)
The brush must move freely within the holder, but with enough spring tension to prevent brush flotation during operation.
INSPECT BRUSH SPRING TENSION New brush length measures 1 1/8 inch (29 mm). Replace the brushes when brush length measures 9/16 (15 mm).If 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 (All Generators)
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.
LUBRICATING BEARING5. 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.

Draining 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 VALVES AND PUMP OUTLETb. Be sure the valve on the engine oil pan line is closed. Marks on the valve
