It is used on machines and equipment using the Eaton Char-Lynn 103 series motor 103-1011-012. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.
The same part is also sold as Eaton 103-1011.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Wheel or drive loses power
A worn orbital motor leaks oil internally and slows down or stalls under load. If the pump delivers full flow and pressure, the motor is the next thing to check.
Oil leaking at the shaft
A failed shaft seal on an old motor usually means the bearings and gerotor are worn too. A complete new motor is often quicker than a rebuild.
Augers, sweepers and conveyors
Orbital motors drive augers, brooms, mixers, winches and conveyors. Keeping a spare of the same number avoids a long stop.
Matching the old unit
Match the full part number, flange, shaft and port type of the old motor. The number is on the label or stamped on the body.

Yes, it is a direct replacement for the Eaton 103-1011-012 with the same fitting.
Often 5,000 to 10,000 hours with clean fluid, much less with dirt or air in the system. It is usually changed on condition, not by hours.
Leaks from the seal or weep hole, noise or whining, overheating, or falling pressure or flow under load.
Most failures come from contamination, cavitation from a restricted inlet, or running low on fluid. Check the inlet and the fluid before fitting the new hydraulic motor.
Clean them right back to metal and fit the new gasket or O-ring dry, unless the engine manual calls for sealant.
No. It is an aftermarket hydraulic motor made to replace the Eaton 103-1011-012. It is not made by the original manufacturer; the number only shows what it replaces.
