Frequently Asked Questions
What floating seal fits a Komatsu D61PX-12 dozer?
Floating seal part number 150-27-00029 fits the Komatsu D61PX-12. The same seal also fits the D61E-12, D61EX-12, D61P-12 and D68ESS-12 dozers. Match the part number on your old seal or in your parts book before ordering.
Which bushing fits a Komatsu D31 or D37 dozer?
Two Komatsu bushings list the D31 and D37 in their fitment: part number 07177-05030 and part number 07177-05530. Because both cover these models, the correct one depends on where the bushing goes on your machine and its serial number. Match the part number from your old bushing or parts book, or call (800) 909-7060 and the parts team can help confirm the right one.
Do you carry bushings for Komatsu D155 and D355 dozers?
Yes, Broken Tractor carries bushing part number 07177-05030, which lists the Komatsu D155 and D355 in its fitment. The same bushing also covers D20 through D75 series dozers, including the D31, D37, D41 and D61. Confirm the part number against your machine before ordering, since fitment can vary by location on the dozer.
What tool do I need to remove and install bushings on a Komatsu dozer?
Broken Tractor offers a steel bushing driver tool built for both removing and installing bushings. It is a universal tool, so it works across Komatsu D-series dozers rather than fitting a single model. It is a useful addition when you are replacing several bushings during undercarriage, final drive or linkage service.
Are bushing kits available for Komatsu D-series dozers?
Yes, Broken Tractor offers bushing kits for multi-point service jobs on Komatsu D-series dozers, along with individual bushings. A kit makes sense when you are replacing bushings at several points at once, while individual bushings work well for a single worn location. Check the listed fitment and part numbers against your model to make sure the kit matches your machine.
