Common questions

Can I replace a K46BT with a K46AC or a K57?

No. Model codes are not interchangeable even within the K46 family: control arms, brake sides and axle lengths differ. Order by the full part number, or send us the serial.

Repair kit or new unit?

A kit is worth it when the unit is low-hours and just worn internally (slips when hot). If it has run dry, ground metal, or the case is damaged, a new unit is cheaper in the end. We'll tell you straight.

Is the unit prefilled with oil?

Most K46 and T40 units ship prefilled with Tuff Tech fluid; the listing says so. Kits do not include oil; you'll want 187Q0899000 (3 L) for an internal-reservoir unit.
