Product Questions & Answers (2)

Question by: Chad C on Feb 2, 2026, 12:34 PM
does this motor need a case drain line hooked up, or can it run without one?
Answer by: Customer Support on Feb 4, 2026, 8:36 AM
For most setups, no external case drain is required. The motor handles up to 2000 PSI of back pressure without one. If your system runs continuous back pressure above that threshold, you'd want to add an external case drain line and make sure it's plumbed so the motor case stays full of fluid at all times. Below that limit, you're fine running it as-is.
Question by: Tommy R on Jul 30, 2025, 9:44 PM
got a 2 bolt SAE A mount and need a 1-1/4 straight keyed shaft. is that what this motor comes with?
Answer by: Customer Support on Aug 1, 2025, 9:09 AM
It matches that setup. It has a 2 Bolt SAE A mounting flange and a 1-1/4 in straight keyed shaft.
