Frequently Asked Questions

What undercarriage parts do you carry for a Case 450 dozer?

Broken Tractor carries a full range of Case 450 series undercarriage components, including top and bottom track rollers, front idler wheels, shafts and assemblies, drive and track sprockets, master pins, and single grouser track shoes with bolt and nut kits. We also stock roller mounting brackets, idler guide plates, wear strip kits, and spacer plates. Coverage spans both early narrow and later wide undercarriage builds.

How do I know if my Case 450 needs the before or after serial number 3050800 undercarriage parts?

Many Case 450 undercarriage parts change at serial break 3050800/3050801, so the correct part depends on your machine's serial number. For example, the early narrow bottom track roller (SKU R24034) fits the 450 before serial 3050800, while the R57357 bottom roller fits the 450 after serial 3050801. Check your serial number and match it to the fitment listed, or confirm with our parts team before ordering.

We offer 14 inch, 16 inch, and 20 inch single grouser track shoes for the Case 450 series. The 14 inch CA270/14 fits the 450 before serial 3050800, while the CA408 series 14, 16, and 20 inch shoes fit the 450, 450B, 450C, and 450C-LT. Matching track shoe bolt and nut kits are also available, such as CA270BK and CA408BK.

Which drive sprocket fits a Case 450 dozer?

The correct drive sprocket depends on your model and serial number. Sprocket R24570 fits the 450 after serial 3050801 and the 450B, D43349 fits the 450 within serial range 3038435 to 3050801, and R52698 and R52699 fit the 450C.
