FAQ

Q1: Will this front idler fit my Komatsu PC60?
This idler is manufactured for the Komatsu PC60, PC60-7, and PC60-8. Please confirm your machine serial number and compare outer diameter, shaft diameter, and mounting dimensions with the table above. Send us photos of your old idler if unsure, and our team will confirm compatibility.

Q2: What is the expected service life?
Under normal operating conditions, expect 5,000–8,000 working hours before replacement. In abrasive conditions, service life may be shorter. Regular track tension checks and seal inspection will maximize idler life.

Q3: Do I need to grease this idler?
No. This front idler is lifetime-lubricated with factory-filled oil and floating seals. No daily greasing is required. If oil leaks from the idler, the seal has failed and the idler should be replaced or rebuilt.

Q4: What causes front idler failure?
Common causes include improper track tension, operation in abrasive materials without cleaning, and failed seals that allow oil to leak out. Worn track chains with excessive pitch can also accelerate idler tread wear.

Q5: Can I replace only the front idler?
Yes, you can replace the front idler independently. However, inspect the track tensioner, yoke, and track chain at the same time. Replacing worn components as a set can save labor costs later.

Q6: Is this a genuine Komatsu part?
This is a high-quality aftermarket replacement manufactured to OEM specifications, not a genuine Komatsu component. It matches OEM fit and performance at a significantly lower price.

Q7: How should I store a spare front idler?
Store in a dry, covered area away from direct sunlight and moisture. Keep it in original packaging until installation. Rotate occasionally during long storage to prevent seal sticking.
