Frequently Asked Questions

Which track adjuster rod fits a Case 550 dozer before serial number JAK13967?

For a Case 550 built before Serial# JAK13967, we carry the Track Adjuster Rod SKU R54460, which also fits the 450C Long Track. Machines built after Serial# JAK13968 use a different rod, SKU R57443. Match your machine's serial number to the correct part, or confirm with our parts team before ordering.

What track adjuster fits a Case 550 dozer after serial number JAK13968?

The Track Tension Adjuster SKU R57442 fits Case 550 dozers built after Serial# JAK13968, and the matching adjuster rod is SKU R57443. Because the 550 splits at this serial break, check your serial number so you get the correct component for your machine.

Do the left-hand and right-hand recoil springs for a Case 550 come separately?

Yes, the recoil spring assemblies are sold separately by side. Broken Tractor carries the Left-Hand Recoil Spring Assembly SKU 187916A2 and the Right-Hand Recoil Spring Assembly SKU 187917A2. Confirm which side you need before ordering, since only the right-hand assembly lists fitment for the 550, 550H.

Which track adjuster parts fit a Case 550E, 550G, or 550H dozer?

For the 550E, 550G, and 550H we carry the Track Adjuster Assembly SKU R58480, the Track Adjuster Chrome Rod SKU R58450, and the Rod Spacer Tube SKU R58451. The Track Adjuster Yoke SKU 389390A1 and Seal Kit SKU 907002 also cover these models. Match the part number to your machine to confirm fitment.

Can I replace just the seal kit or yoke instead of the whole track adjuster on a Case 550?

Yes, Broken Tractor offers individual components so you can replace only what is worn. We carry the Track Adjuster Seal Kit SKU 907002 and the Track Adjuster Yoke SKU 389390A1, both covering a wide range of 450 through 550H dozers. If you need a full unit instead, complete adjuster assemblies are also available.
