Question by: Shawn C on Mar 6, 2026, 8:57 AM
Motor says bi-rotational, does that mean I can just flip the port connections to reverse which way the shaft spins, or is there more to it than that?
Answer by: Customer Support on Mar 7, 2026, 4:15 PM
Bi-rotational means the motor is built to run in either direction without any internal modification. On a gear motor like this one, swapping which port receives pressure and which returns to tank is all it takes to reverse shaft rotation. The -8 SAE rear ports on this unit make that swap straightforward in most plumbed setups. No special valving is baked into the motor itself, so direction control comes down to however your circuit is configured.

Question by: Neal F on Jun 12, 2025, 8:25 PM
got a small power unit build, what size is this motor and how’s it mount up?
Answer by: Customer Support on Jun 14, 2025, 4:43 PM
For sizing, it is a 0.194 cu in per revolution gear motor. Mounting is SAE A 2-bolt, so it bolts to an SAE A 2-bolt flange pattern.
