How we match Main Winch Gearbox

Gearbox housings may look similar while internal ratios, input connections or output arrangements differ. Matching therefore starts with available markings and the complete winch configuration, not appearance alone. Do not remove or discard the old unit before recording its interfaces.

FAQ

Main Winch Gearbox questions

Can a gearbox be selected by its external housing?

No. Similar housings may use different internal or interface configurations. Markings and both connection sides are needed.

Should the hydraulic motor plate also be photographed?

Yes. The connected motor information helps verify the gearbox input-side configuration.
