Replacement rubber tracks for the Kubota U17 mini excavator in 230x48x70 — 230 mm wide, 48 mm pitch, 70 links. Built for digging, trenching, backfill and tight-quarters work, with free freight to the lower 48.
What the numbers mean on a Kubota U17
- 230x48x70 — 230 mm tread width (about 9"), 48 mm pitch, 70 links
Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.
Tread choice for the Kubota U17
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- MX — mixed and hard surfaces. A durable general-duty excavator tread
Undercarriage parts for the Kubota U17
Rollers, idlers and sprockets wear on the same clock as the track. Fitting new rubber over a hooked sprocket or a seized roller is the fastest way to lose the new track — check these while the tracks are off:
- Drive sprocket — SPRB238-14430
- Front idler — FIRA231-21300
- Bottom roller — TRRA231-21700
How these wear
Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.
Same track, other machines
Track size follows undercarriage geometry, not brand, so 230x48x70 shows up on machines from several makers. If you run any of these alongside the Kubota U17, it is the same belt:
- 301 8
- Airman AX17U
- Bobcat E17Z
- CAT 301.5CR
- CAT 301.6C
- CAT 301.7
- CAT 301.8C
- Case CX14
- Case CX15STC
- Case CX15STR
Not sure which you are running? Read the size off the inside of the old track, or call (850) 816-7898 and we will pull it off the machine record. The Track Finder works by make and model too.
