The Case CK35 is cataloged in more than one track width — 300 / 350 mm. Pick the width your undercarriage is actually set up for, then choose tread for the ground you work. Free freight to the lower 48 on every track, 24-month warranty.
Which width fits your Case CK35
- 350x52.5x86 — 350 mm (14") wide, 52.5 mm pitch, 86 links
- 300x52.5Wx86 — 300 mm (12") wide, 52.5 mm pitch, 86 links, wide guide lugs
These are not interchangeable by preference — the width your machine takes is set by the roller frame and sprocket it left the factory with. Wider tread floats better on soft ground and spreads ground pressure; narrower runs cheaper, turns easier and clears tight spots. Measure the existing track across the tread face before you order.
Tread choice for the Case CK35
Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:
- Directional — digging, trenching and slope work. The standard excavator tread
Undercarriage parts for the Case CK35
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:
- Carrier roller — PV64D00001F1
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 one of these sizes shows up on machines from several makers. If you run any of these alongside the Case CK35, it is the same belt:
- Case 35MAXI
- Case CX35
- IHI T840
- JCB 804
- JCB 804PLUS
- Kobelco SK035
- Kobelco SK035-1
- Kobelco SK035-2
- Kubota KX040-4
- Takeuchi TB035
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.
