Frequently Asked Questions

What is the difference between 6-roller and 7-roller adjuster rods?

The adjuster rod length differs by roller count on these machines. The 6-roller rod runs shorter while the 7-roller rod is longer for the extended Long Track and LGP undercarriage. Match your machine roller count and confirm the part number before ordering.

Are the recoil spring assemblies for the 1450B side specific?

Yes, some recoil spring assemblies are left or right specific on the 1450B and 1455B. We offer left and right no-step versions, so verify which side you need before ordering.

Does the track adjuster seal kit fit a Case 1450B?

Yes, we carry a track adjuster seal kit that fits the 1450, 1450B, 1455, 1455B, and 1550 among other Case dozer models. It is used to service the track tension adjuster cylinder.

How do I know which track tension adjuster fits my dozer?

Fitment depends on your model and roller configuration, since 6-roller and 7-roller machines use different adjusters. Match your machine details to the part number, or call our parts team at (800) 909-7060 to confirm.
