20,000lb winch question

bigred350 · Sep 4, 2019

Hi there, I have a line on a very nice 20k front winch with levelwind off a m813. Want to put it on my m931, I know I have to get all the hydraulic components but my question is will the hydraulic motor bolt up to the older style shaft driven winch?

Yes. Member 162Tcat has a few motors

Yes, the winch assembly itself is exactly the same. Adapter parts and -numbers are described in TM 9-2320-272-24P-2, Fig. 470.

Some pics of those parts can be seen here, also.

Anyone have the pump specifications mentioned above. IE, psi, gpm, etc?
Thanks in advance.

The pump is rated at 27gpm and 3000psi max. However the control valve needs to be set to bypass at 1750psi +_ 150 to keep from overloading and breaking the winch.

Also pulls 62.5 hp, full load, at the pump rated max of 2700rpm.
I can’t remember the pto ratio but I’m thinking at the maximum 1800rpm engine speed while operating the winch, the pump probably runs at 2700?

Thanks jbulach for the hydraulic information.
