Genuine factory seal kits for orbital hydraulic motors. A leaking motor is usually a shaft seal, not a worn motor - and a kit is a fraction of the price of a replacement. Every kit here is the manufacturer's own kit for that motor series, not a generic assortment.

What is in a kit

Shaft seal, housing and end cover O-rings, the port and case drain seals, and the dust or exclusion seal where the design uses one. Bolt torque figures and the seal pressure rating are on the listing - worth reading, because fitting a standard-duty seal to a motor that runs at high pressure just moves the problem.

Finding the right kit

Match the kit to the motor series, not the displacement: one kit covers the whole displacement range of a series. If you have the motor's part number, the series is the letters at the front of the code. If you have no code left to read, the mount pattern, shaft type and port size together will identify it - send us a photo and we will tell you which kit you need.

Before you fit it

If the shaft seal has failed and the motor has been run low on oil, check the shaft and bearing for play before you spend time on a reseal. If there is measurable movement at the shaft, the kit will buy you weeks rather than years. Fill the motor with clean oil and run it at moderate load for five to ten minutes after a reseal to bed everything in.
