1.	Record Complaint:


2.	Pre-repair contamination control.
	A.	High-pressure wash the rear half and sides of the tractor to remove all dirt/debris.
	B.	Maintain a well-organized work area and plan to contain all fluid spills.
	C.	Keep components in original shipping package until installation, to keep clean.
	D.	Verify new parts cleanliness. Assure that they are cleaned, capped, and protected against dirt.

3.	Investigate final drive history or failure cause, if appropriate.
	A.	Question the operator on application, operating conditions, and history. Review SOS history.
	B.	Review VIDS for detected fault information and record in work order folder.
	C.	Take SOS Sample refer to: Contamination Control Guidelines, SEBF8482, "Obtaining Oil Sample for Analysis". Drain the engine and related power train oil reservoirs and visually check oil for water, coolant, or debris contaminants.
	D.	Remove/inspect system filters/screens and save any contamination evidence.

4.	If a clutch or brake failed generating metal/debris, remove, clean, and inspect/repair the torque divider, transmission, and bevel gear group. Clean the power train oil reservoir and all vulnerable oil system screens/components (reference the System Operations manual). Use the Caterpillar R&I checklists as needed.

5.	Cover and cap all cleaned and reused components/lines until installed to prevent dirt entry. Cover all removed component cores with plastic sheets until shipping covers are available.

6.	Inspect axle shaft splines, axle thrust wear surfaces, and final drive cover for excess wear. Refer to Reuse And Salvage Guidelines, SEBF8126, "Universal Joints and Drive Shafts". Spline tooth wear limit is 0.2 mm (0.008 inch).

7.	Inspect final drive mounting area and machine frame for wear, stripped threads, cracks, or deformation. Repair/replace and paint as needed.

8.	Inspect the power train filter bypasses and bypass indicators for correct operation. Install 6 micron "clean-up" filters in the torque divider system. Use the clean-up filters for at least 8 hours operation time.							Filter part number: __________

9.	Thoroughly clean mounting surfaces on machine frame. If removing transmission, bevel gears, and steering clutches/brakes, thoroughly clean frame cavities with a high pressure/temperature wash. Use lint-free towels to clean and check cleanliness. Cover openings to keep clean.
	Supervisor sign-off required.

10.	Clean/protect all mounting surfaces and exposed cavities of the replacement components.

11.	Transfer all covers/plugs to the cores. Tag with completed Cat dealer core tag.

12.	Fill all power train compartments with oil meeting ISO --/16/13 cleanliness level. Wait 10 minutes and check oil level.

13.	Check clutch & brake pressures. Refer to procedures detailed in the Testing & Adjusting manuals.

14.	Perform brake hold test. Test run machine and inspect for leaks.

15.	Before releasing machine, test the final drive(s) and transmission sump oil cleanliness. Kidney loop filtration (reference SEBF8465) may be required to achieve ISO levels of --/18/15. Attach particle count printouts and record test results.						Final Drive Right:
							Final Drive Left:
							Transmission:

16.	After 8 hours of operation without bypassing the filters, inspect the clean-up filters and install new standard power train filters (2).							New filter part number: __________
	After 8 hours of operation, check component and related systems for leaks. After one running shift and within 24 clock hours of installation, take a power train system oil sample. Send the sample to the Cat dealer with this checklist, completed, and signed. At 250 operating hours, perform valve lash check and adjustment. Refer to the Test and Adjust manual. At 4,000 operating hours, perform tests in Step 13 and report the results to the Cat dealer.
