Getting a 40‑Year‑Old Kubota KH90 Back on Its Tracks—Literally
Buy KH90 Steel Tracks
When Kubota launched the KH‑series mini‑excavators in the mid‑1980s (the KH90 debuted around 1984) they were compact powerhouses built to last. Fast‑forward four decades and many KH90s are still earning their keep—but only if their undercarriages hold up.
That was the challenge one farmer faced when he rang our SteelTracks.com desk last month. His KH90’s bushings were blown out, the chain links were so thin you could see daylight around the pins, and the local dealer politely declined the job (“too old, too tricky, too risky”). Ordering the wrong chain on a vintage machine is an expensive mistake—so dealers tend to avoid it.
A Tape Measure, a Few Photos, and a Lot of Patience
We walked the customer through a detailed inspection:
- Pin‑to‑pin pitch of the existing chain
- Height and tooth count of the drive sprockets
- Diameter & flange style of rollers and idlers
- Clear side‑profile photos of the old track wrapped around each component
With those numbers (and the customer’s photos) we were 99 % sure we could spec a new steel track assembly that would bolt straight on. The customer pulled the trigger, we shipped the tracks, and installation happened the same afternoon. A farm truck and tractor provided the muscle to snake the chain over the sprockets; the 15 mm master pin tapped in with minimal fuss. By nightfall the KH90 was trenching again—and its owner was “over the moon.”
Why It Worked
- Collaborative diagnostics – precise measurements and clear photos remove the guess‑work.
- Deep parts library – decades of cross‑reference data let us match even out‑of‑production Kubota models.
- Risk mitigation – getting it right first time saves both customer and supplier from costly returns.
