Maintenance Tips for CAT Final Drives

✔ 1. Check Oil Levels Weekly

Low oil is the number one cause of gearbox failure.

✔ 2. Replace Gear Oil Every 500 Hours

Dirty oil destroys bearings and gears.

✔ 3. Inspect for Leaks

Oil around the sprocket area indicates a failing seal.

✔ 4. Avoid Over-Tight Track Tension

Tight tracks = overheating & accelerated wear.

✔ 5. Clean Travel Motors After Mud Work

Mud buildup keeps heat inside the drive.

✔ 6. Use OEM or High-Quality Oil

Cheap oil leads to early failure.

✔ 7. Replace Bearings & Seals During Overhaul

Do not reuse worn components — it reduces lifespan.
