Three ways to find the right motor
Replacing one that has failed? Use the interchange chart. Building something new? Pick by displacement. Not sure what you have? Text us a photo of the tag on 0440 137 103 and we will identify it for you.
1. Replacing a motor - find yours in the chart
Read the code off the old motor and pick your replacement straight from this chart. Both columns bolt into the same place - the premium line is made in Europe and carries the longer duty cycle, the value line does the same job for less money.
| If the tag on your old motor says | Premium replacement (M+S, Europe) | Value replacement (Zhenjiang) |

Cannot see your code, or it reads as a long product number like 101-1003-009? Text or ring us - we identify motors off the tag every day.
2. Building something new - pick by displacement
Displacement sets speed and torque for a given flow. More cc means more torque and slower rotation at the same litres per minute. Every motor below lets you choose your mount, shaft, seal and port position on the product page.
| Displacement | Typical jobs | Start here |
|---|---|---|
| 8 to 50 cc | Small fans, brushes, dispensers, seed and fertiliser augers | MM BMM |
| 36 to 100 cc | Augers, conveyors, sweeper brushes, small winches | MP HP BMP BMPH |
| 100 to 250 cc | Post drivers, feed mixers, bale unrollers, wheel drives | MR MLHR BMR |
| 250 to 500 cc | Heavy augers, large winches, track drives | MH MS BMSY |
| 500 to 800 cc | Drilling, forestry heads, mining attachments | MT MV BMT BMV |
3. Gerotor, Geroler or Disc Valve - what is the difference?
All three bolt up much the same way. What is inside decides how hard you can work them.
Gerotor - the standard workhorse
What is inside: A gear set slides against the stator. Simpler build, lower cost.
Suited to: Fans, augers, sweeper brushes and conveyors. Lighter duty, intermittent running.
Geroler - more torque, longer life
What is inside: Hardened rollers sit in the stator pockets, so the contact rolls rather than slides.
Suited to: More torque from the same frame size and much less internal wear. Winches, wheel and track drives, augers that work all day.
Disc Valve - the heavy end
What is inside: A flat rotating disc does the porting instead of a spool, so it seals better as pressure rises.
Suited to: High pressure, high torque, long duty cycles. Drilling, large drives, forestry and mining attachments.
Still not sure? Ring 1300 1 HOSES or text a photo of the motor and the machine to 0440 137 103. We would rather spend two minutes getting it right than have you send one back.
Orbital motors — gerotor, geroler and disc valve — are the workhorse low-speed high-torque motors on augers, slashers, sweepers, conveyors, winches and drives. Every series below is one tile: value-line and premium European ranges, smallest to largest, with the size on the tile. They interchange with Danfoss OMM, OMP, OMR and OMS, White, Eaton Char-Lynn, Parker and Bosch pattern motors — the interchange codes are on every listing. Match the code on your nameplate, or call 1300 146 737 with whatever is written on the tag.
