Question by: Chad B on Jul 30, 2025, 11:30 AM

got a trencher that needs a new drive motor and I keep seein this one pop up, is the 4000 series actually built for that kind of work or is it more of a light duty unit?

Trenching is one of the listed applications for this motor, so it's not a stretch at all. The 4000 Series is a cast iron Geroler unit rated at 485 Nm of torque and handles flow up to 95 litres per minute. That combination is squarely aimed at mobile equipment doing real work, not just light-duty stuff. The low-speed Geroler design also keeps pressure drop lower than comparable motors in its class, which helps when you're running equipment hard across a full shift.

Reckon this Char-Lynn motor would hold up okay on a wood splitter?

Answer by: Customer Support on Mar 5, 2026, 6:52 AM

Application-wise, it's plenty suitable for wood product equipment, so it should do the trick. Torque rating's at 485 Nm and it can handle up to 95 litres per minute flow rate.
