Rubber track tension is one of those “small things” that quietly decides how long your undercarriage lasts.

Over-tightening adds stress to rollers and idlers. Running loose increases derailment risk.

Correct tension protects the entire system — and it only takes a few minutes to check.

This guide shows the method we actually use on site.

How to Measure Rubber Track Size (Quick Guide) Rubber track size is NOT just the machine model. Correct format: Width × Pitch × Links Example: 400 × 72.5 × 74 Common errors:

Guessing size

Wrong pitch measurement

Missing link count Best advice: Measure the old track before ordering. Helpful guide for anyone working with mini excavators or compact loaders.

[best-mini-parts]

Rubber tracks are widely used on mini excavators, compact loaders, dumpers, and agricultural machines.

A typical rubber track size looks like this: 400 × 72.5 × 74

400 mm – track width

72.5 mm – pitch (must match the sprocket)

74 – number of links

Correct sizing improves undercarriage fit, reduces wear, and extends service life.

When in doubt, selecting rubber tracks by machine model is the most reliable method.
