Frequently Asked Questions
What size rubber track does the Kobelco SK45-1 use?
The Kobelco SK45-1 uses a 400x72.5Nx74 rubber track. Note the N (narrow 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 Kobelco SK45-1?
Yes — this track is matched to the Kobelco SK45-1 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.
How do I confirm the right track size for my Kobelco SK45-1?
Read the size stamped on the inside of your current track, or measure width x pitch x links. Not sure? Message us and we'll match it.
How fast will my track ship?
In-stock tracks ship fast from US warehouses, most within 1–2 business days, with tracking sent as soon as it leaves the dock.
Do Kobelco SK45-1 tracks sell in pairs?
Tracks are priced individually; a full machine needs two. Most owners replace both at once so wear stays even.
