Product Questions & Answers

What exactly is the shaft configuration on this unit? Trying to figure out if it'll mate up with what I already got on the pump.

Question by: Pete Y on Feb 14, 2026, 6:13 PM

Built around a 1-3/4 inch SAE B spline shaft, so it follows the standard SAE B bolt pattern and spline spec. If your existing setup is already matched to SAE B spline dimensions at that shaft size, you should have a direct fit without any adapter needed.

So, this thing's got a 1-3/4 SAE B-SPLN, right? What exactly does that mean for hookin' it up to other stuff?

Question by: Stan B on May 3, 2025, 8:16 PM

That spline specification refers to the shaft where you'd connect this Permco unit to the rest of your hydraulic system. It's a standardized size, so as long as your mating component also has a 1-3/4 SAE B-SPLN, it should fit right up.

i’ve got a Permco 257 gear pump and need the g/shaft set, is this the one with the 1-3/4 SAE B spline?

Match-up is based on the shaft style and size. This part is a Permco 257 G/SH set with a 1-3/4 SAE B spline, so it fits applications calling for that exact shaft configuration.
