4020 Hydrualic Pump

[Tim14167]

I have a 1965 John Deere 4020PS and the front hydrualic pump has blown out. I have access to a hydrualic pump from a 4840, will this fit in? Thanks

Yes it should fit as JDparts.com shows the pump listed for a 4840 2WD is the same as a 4020. Is your hyd pump leaking or is housing cracked?

The threads that hold the plug (valve) in blew out. Years ago I had the same issue and I had the plug drilled and tapped oversized and made an bushing to adapt the valve into the oversized plug. This was done a couple of times over the years. Its time for a new pump.
