Komatsu PC45MR-5 Undercarriage Maintenance Guide

Signs You Need New Rubber Tracks

•Visible cracks in the rubber surface
•Missing or damaged track lugs
•Exposed or damaged steel cords
•Excessive track stretching or looseness
•Uneven wear patterns across the track
•Reduced traction or slipping

Common Causes of Track Wear

•Operating on rough or abrasive surfaces
•Improper track tension (too tight or loose)
•Excessive turning on hard surfaces
•Exposure to chemicals, oil, or fuel
•Worn sprockets, rollers, or idlers
•Operating beyond recommended load capacity

Maintenance Tips for Your Komatsu PC45MR-5

Check Track Tension Daily

Proper tension extends track life. Too tight causes premature wear; too loose risks de-tracking.

Inspect Undercarriage Weekly

Check sprockets, rollers, and idlers for wear. Replace worn components to prevent track damage.

Clean Tracks Regularly

Remove debris, mud, and rocks from tracks and undercarriage. Prevents premature wear and damage.

Avoid Sharp Turns

Gradual turns reduce track stress. Sharp turns on hard surfaces accelerate edge wear.

Match Track to Application

Use the right track tread pattern for your work surface. Different applications require different tracks.

Store Properly When Not in Use

Park on flat surfaces. Avoid prolonged exposure to direct sunlight and chemicals.
