Udor pump series question

Yeah that’s what I thought, I just got a little confused by the way you worded it. I never done it before myself but I could’ve sworn I’ve read on here and million times that you can just bolt on whatever onto the motor. Thank you for the clarification though!

You can take a direct drive pump off a gx390 and bolt on a gear drive pump with 4 bolts and you’re good to go. As stated here…you can’t just throw a gear box on a direct drive pump

Don’t forget the gearbox in between!

Yeah, the gear drive is a lot bigger and may not fit on the cart.

Here’s a pic of my 5.6 General gear drive and my 4/4 General pumps when I made the swap. You can see the contrast and size difference. While it’s larger, the footprint itself isn’t much larger compared to belt drive

What size bolts did you use to mount the pump to the engine?
