Frequently Asked Questions

Which track adjuster fits a Dresser TD7 or 100 series dozer?

For 5-roller TD7C, TD7E, TD7G, TD7H, 100C, 100E and 100G dozers, Broken Tractor offers the Dresser Dozer Track Tension Adjuster, SKU PV307X. We also carry SKU PV307AX, which is listed for the TD7G and TD8H. Check your model, generation and roller count before ordering, since adjuster assemblies are model-specific.

What track adjuster do I need for a Dresser TD8, TD9H or 125 dozer?

The correct adjuster depends on your exact model. SKU PV308X fits 5-roller TD8C, TD8E, TD8G, 125C, 125E and 125G dozers, and SKU PV308AX is listed for the TD8G. SKU PV307AX covers the TD8H, and SKU PV3089X is made for the TD9H. Match your model and roller count to the listing, or compare against the part number on your old adjuster.

Which track adjuster seal kit fits an International TD7 or 100 dozer?

It depends on the serial number. Seal kit SKU 906000 fits early International TD7 and 100 dozers before serial number 9500. Kit SKU 906001 fits the later Dresser C, E, G and H generations, including TD7C through TD7H, TD8C through TD8H, TD9H, 100C, 100E, 100G and 125C, 125E and 125G. If you are unsure which serial range your dozer falls in, call (800) 909-7060 before ordering.

Can I replace just the piston or rod in a Dresser dozer track adjuster instead of the whole assembly?

Yes, Broken Tractor carries individual adjuster components along with complete assemblies. Piston 622049C1 and adjuster rod 621448C3 fit TD7 and TD8 series dozers along with 100, 100C, 100E, 125C and 125E models. Pair them with the matching seal kit for your serial range, and confirm your model appears in the fitment list before ordering.

Which idler wear plate fits a Dresser TD8 compared to a TD7?

TD7 and TD8 dozers use different idler wear plates, though one wear plate fits both. Wear plate 621338C1 fits TD7C, TD7E, TD7G, TD7H, 100C, 100E, 100G and TD8H dozers. Wear plate 662526C1 fits TD8C, TD8E, TD8G, TD9H and 125C, 125E and 125G. Wear plate 622221C1 is listed for all TD7, TD8, TD9H, 100 and 125 C, E, G and H models, so compare part numbers against your old plates before ordering.
