Introduction
This Special Instruction contains the rework procedure for providing more lubrication to the transmission clutch number three by adding a drilled hole to the 509-9173 Carrier As.
Do not perform any procedure in this Special Instruction until you have read and understood the information.
Safety Section
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility. |
Failure to follow all safety guidelines prescribed in this document and by governing authorities and regulatory agencies may result in severe injury or death of personnel or machine damage. |
When removing a major component or attachment, ensure that it is properly blocked or secured before removing mounting hardware. An assembly that is disconnected without proper blocking may shift or fall, resulting in serious injury or death of personnel or machine damage. |
Personal injury or death can result from improper maintenance procedures. To avoid injury or death, follow the procedures exactly as stated below. |
Personal injury can result from improper handling of chemicals. Make sure you use all the necessary protective equipment required to do the job. Make sure that you read and understand all directions and hazards described on the labels and material safety data sheet of any chemical that is used. Observe all safety precautions recommended by the chemical manufacturer for handling, storage, and disposal of chemicals. |
Climbing equipment may be required to access this service point. Refer to the Operation and Maintenance Manual, "Mounting and Dismounting" topic for safety information. |
Before servicing/performing maintenance on the machine, electrical power must be physically disconnected; battery plugs must be disconnected from the batteries, or the trailing cable must be unplugged, and warning tags and padlocks shall be applied by a certified electrician. Certified electricians shall perform or direct any electrical work, including any energized testing, repair work in controllers, motors, or other approved compartments, and shall insure that all compartments are properly closed and inspected prior to re-energization. All applicable lock out and tag out procedures must be followed. |
Do not operate the machine if any guards or covers are missing or inadequately secured. Personnel could be seriously injured or machine damage may occur. |
Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads. |
Rework Procedure for Providing More Lubrication to the Transmission Clutch Number Three
- Locate machining locator button (A) shown in Illustration 1.
- Mark 1, 2, 3, 4 on the top of carrier and planet shaft starting from machining locator button (A) in the clockwise direction.
Note: The marked locations will be used later to reassemble the gears, bearings, and shafts to their original locations.
- Remove and save the planet shafts, gears, and bearings from the carrier.

(C) Port - Locate position to drill one
1.5 mm (0.06 inch) hole at 25 degrees to intersect with lube passage shown in the Illustration 3.Note: One drill hole per piece part.
- If a new 289-4704 Plug (avdel plug) and supplier tooling are available, remove avdel plug (B) shown in Illustration 2.

Illustration 4 g06426525 509-9173 Carrier As - Set carrier assembly on radial drill. Drill one
1.5 mm (0.06 inch) diameter hole to intersect lube passage.Note: One drill hole per piece part.
Note: If required, use end mill of
1.5 mm (0.06 inch) diameter before drilling to a depth of3 mm (0.12 inch) .Note: Start drilling at the natural crease of the piece part geometry to aid ease of drilling.
- Blow out the chips and wash out.
Note: Use port (C) to blow the chips, if avdel plug is not removed.
- Inspect the drilled hole using a flashlight or bore scope. Ensure that the hole is clear and has no debris.
- Install a new 289-4704 Plug if avdel plug (B) is removed in Step 5.
Note: Ensure that the plug is not protruding from the hole. The plug must be flush with the top of the carrier.
- Reassemble gears, bearings, and planet shafts saved in Step 3. Install with new 3S-2708 Spring Pin at each location.
