Case CX37C Rubber Tracks & Parts

Q: What size rubber tracks fit a Case CX37C?

The Case CX37C can use 300x52.5x86 or 300x52.5x86 rubber tracks. Match the full size on the track you are replacing before you order. If your machine has more than one track setup, choose the width and guide style that matches the track currently on the machine.

The Case CX37C is listed with more than one build of the same 300 mm track. Match link count to what is on the machine now. Free freight to the lower 48, 24-month warranty.

Case CX37C track options

300x52.5Kx86 — 300 mm (12") wide, 52.5 mm pitch, 86 links, K-lug guide lugs
300x52.5Nx86 — 300 mm (12") wide, 52.5 mm pitch, 86 links, narrow guide lugs

Same tread width on all of them — what changes is pitch and link count, which is set by the sprocket and roller frame. Read the numbers off the inside of the old track rather than going by model year; these were built across more than one undercarriage spec.

Tread choice for the Case CX37C

Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:

Undercarriage parts for the Case CX37C

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 — 6813372

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 CX37C, it is the same belt:

100% Virgin Rubber
Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.
Continuous Steel Cords
Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.
Drop-Forged Links
Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.
Corrosion Resistant
The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.
Reinforced Sidewalls
Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.
Low-Vibration Tread
Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.
