Frequently Asked Questions
What size rubber track does the Komatsu PC35MR-3 use?
The Komatsu PC35MR-3 uses a 300x52.5Kx86 rubber track. Note the K guide guide-lug type — other guide types won't seat correctly on the rollers. Always confirm against your current track or the machine's spec plate, since some units shipped with more than one option.
Will this track fit my Komatsu PC35MR-3?
Yes — this track is matched to the Komatsu PC35MR-3 by size and tread pattern. If your machine has a serial break or factory option, send the serial number and we'll verify fitment before shipping.
Do you stock undercarriage parts for the Komatsu PC35MR-3?
Yes — along with the rubber track we carry bottom rollers, drive sprockets, top rollers for the Komatsu PC35MR-3, so you can refresh the whole undercarriage in one order.
Directional or block tread — which should I run?
For mixed dirt and gravel, most Komatsu PC35MR-3 owners run a directional (multi-bar) tread for traction and mud release. Block tread wears better on hard surfaces and pavement.
What warranty comes with Komatsu PC35MR-3 tracks?
Our rubber tracks carry a 24-month warranty against manufacturing defects, with continuous steel cords and wear-resistant compounds. Technicians by trade; heavy duty comes standard.
