Undercarriage

Avoid possibility of fire. Trash build-up can cause fire from increased friction. Remove trash from trash build-up points (G) between track and tractor frame.

Avoid operating tractor in grease, oil, or other petroleum chemicals. Avoid spilling these materials on track and wheels during service. Replace mid-rollers in sets if significant thickness wear is seen on an opposite side wheel.

Do not pair worn idlers or mid-roller wheels with new wheels on the same axle. Overloading of the opposite side mid-roller may occur. Or correct track alignment may become more difficult in the case of different circumference idler wheels.

1. Remove any debris or material buildup on top of frame reaction arms. Buildup can wear down rubber on drive wheels and reduce their ability to transfer power to track.

2. Check for material buildup between drive wheels and front idler wheels. Buildup can damage or crush guide lugs and increase chances of derailing track. If drive lug tip damage is seen, it may be due to material buildup.

3. Check for material buildup inside the sprocket, in sprocket pockets where the drive lug engages, or on outer surface of sprocket. Remove any buildup in pockets or external surface to avoid damage to track and drive lugs. If material buildup is noted on sprocket, adjust scraper if required.
