Seal Fitment and Compatibility

Seals split into two worlds that rarely overlap. Cab and door seals keep weather, dust, and noise out of the operator station, and they match by profile and length. Hydraulic and shaft seals keep fluid in and contamination out, and they match by shaft diameter, bore, and cross-section. Common replacements include the door seals replacing OEM 7281063 and 7319009, the door seal sold by the foot replacing OEM 7011039, the hydrostatic drive motor seal kit replacing OEM 6689774, the quad ring seal replacing OEM 6646372, and the shaft seal replacing OEM 6513090.

Door seal sold by the foot is the practical choice when a cab needs a full perimeter rather than one damaged section, since ordering the exact run avoids splices in the corners where leaks start.

Types of Replacement Seals

Door and cab seals are extruded profiles, usually bulb or D-shaped, that compress against the frame. Shaft seals ride on a rotating shaft with a lip and often a garter spring. Quad rings replace O-rings where a four-lobed profile resists rolling in dynamic positions. Seal kits bundle every seal for one assembly, which is the right way to rebuild a hydrostatic drive motor because opening it for a single seal costs the same labour as doing all of them.

Wind noise and water at the floor point to door seals. Weeping at a shaft or cylinder points to the hydraulic side. Replacing a shaft seal without inspecting the shaft's wear groove is how a new seal ends up leaking within hours.
