Product Questions & Answers

running a 35VQ21A on a log splitter setup and need to confirm the shaft size before I order. what size and type are we talking here?
Question by: Peggy J on Dec 5, 2025, 4:56 PM
The shaft on this pump is a 1-1/4 inch straight keyed configuration. As long as your coupler or drive is set up for that size and style, you should be good to go. Worth double-checking your keyway dimensions on the driven side before you button everything up.

Will this pump bolt right up to a standard SAE C mount?
Question by: Floyd B on Apr 15, 2025, 10:47 AM
It does use a 2-bolt SAE C mounting flange, so it should fit any standard C mount.
