✅ Steps to Check Track Roller Wear:
1.Clean the Undercarriage Parts
Remove dirt, mud, and debris from the rollers and undercarriage to ensure accurate inspection.
2.Visual Inspection
Look for:
Cracks or dents
Oil leaks (indicating seal failure)
Abnormal wear patterns
Flange damage
3.Measure Diameter with Calipers or a Track Gauge
Use a vernier caliper or OEM-specified track gauge to measure the roller body diameter.
Compare the measured diameter to the new (OEM spec) and worn limit values.
4.Check Flange Wear
Inspect the roller flange for rounding, chipping, or thinning. Excessive wear may cause derailing.
5.Rotate the Roller
Spin the roller manually. If it feels rough, wobbly, or doesn’t rotate smoothly, internal components may be damaged.
6.Check for Side-to-Side Movement
Grab the roller and push it side-to-side. Excessive play means the bushing or shaft may be worn.
7.Inspect Oil Levels (for sealed rollers)
Some rollers are oil-filled. If there’s a plug, open it and check the level or for signs of contamination. Wear Limits (Example for Reference)
| Roller Type | New Diameter | Worn Limit |
| Bottom Roller | 170 mm | 155 mm |
| Top Roller | 140 mm | 125 mm |
