Always a good call!
Timj wrote: Tue May 02, 2023 2:43 pm What is the shaft configuration and diameter of that Ultra motor? Is it threaded to the pulley?
I ask because I have ran into a few mentions that the Ultra motor used an 11/16" shaft diameter.
Yessir, 11/16" keyed straight shaft with a 7/16-20 threaded end and a nut to hold the pulley on.

Here's the relevant excerpt from the specs drawing I posted for it. (Click on the photo, it's big)

Thanks, this satisfies my suspicions. A couple of years ago someone posted on CCI that this motor

was a direct drop in replacement for all the AHRM hydraulic motors. I did a lot of digging into it but couldn't confirm the information. This motor may be a replacement for the Ultra motor but definitely not for the Webster or Barnes motors.

Yeah, Zwei is the biggest Parker Gear Motor distributor in the US, so it makes sense that they'd be the ones to sell you a Parker PGM511 style gear pump! :cheers:

Their customer service rep wanted to sell the motor but definitely didn't want to get the shaft specs.
I tracked the part number back to Parker but at the time their site said that motor was imported and to contact them for specs as they didn't have them online. No one replied to my request

My AHRM48 and AHSB48 both have the Webster motor which has a 3/4" x 2" keyed shaft.

@dhitching do you still have your ahrm60 deck apart?
If you do I'm curious about the drive pulley attachment to the motor and size of the hole in it.

The parts manuals do not list separate pulleys for the Ultra motor which you would expect with the different shaft size and configuration.

It's all stored away right now until I get some hydraulic hoses purchased. Once I get it out again I'll measure that for you.

It's worth noting that I'm not sure the Ultra motor is stock on the deck. The hose routing doesn't look like something that was designed in my opinion.

Thanks, no rush. I'm just trying to piece together some of the mystery of the hydraulic motors Ingersoll used. :highfive:
