Frequently Asked Questions

What steering clutch discs fit a Cat D4 6U or 7U dozer?

Broken Tractor carries a steel steering clutch disc (2B3532) and a metallic steering clutch disc (4F1858) for the Cat D4 6U and 7U series built before serial number 26502. Fitment on these D4 discs depends on serial number, so check your machine's serial plate before ordering. If your D4 is outside that range, match the part number on your old disc or call (800) 909-7060 to confirm with the parts team.

What is the difference between steel, metallic and fiber steering clutch discs on a Cat dozer?

They are different disc types made to suit different steering clutch pack configurations, so the right one depends on how your clutch pack is built. We carry steel and metallic discs for most Cat dozer series, plus a fiber disc (6S3183) for the D3. The safest way to get the right disc is to match the type and part number of the discs coming out of your machine.

What steering clutch discs fit a Cat D3C, D4C or D5C dozer?

We offer two steel discs (9P6903 and 9P7101) and two metallic discs (6Y7935 and 6Y7934) for the Cat D3C, D4C and D5C. The 6Y7935 metallic disc also fits the D3C III, D4H, D5C III and D6D, while the 6Y7934 also fits the D3C III, D4C III, D5C III and D4HTSK II. Since several discs share these models, match the part number on your existing discs before ordering.

What steering clutch discs fit a Cat D5 or D6 dozer?

Broken Tractor carries a steel steering clutch disc (1A3987) and a metallic steering clutch disc (2F8621) that fit the Cat D5 and D6. Both are replacement wear components for steering clutch service and rebuilds on these track-type dozers. Compare the disc type and part number with the ones you remove to make sure you order the correct match.

What steering clutch discs fit a Cat D2 or D3 dozer?

For the Cat D2 we carry a steel disc (4B3532) and a metallic disc (5H8530). For the D3 we offer a steel disc (2H6936), a metallic disc (3F5504) that also fits the D4, and a fiber disc (6S3183). Fitment can vary by series, so match the part number on your old discs or confirm with our parts team before ordering.
