Hydraulic Pump Recommendations and Prices

1964 Massey 65 Diesel UNDM 704769 Utility

My lift is still "twitchy" after replacing the chocolate milk hydraulic fluid. I believe this to be sticky valves from reading here.
I think I should replace the pump while I'm into the machine.
All the tools I need are here and it would just be easier to just bite the bullet and do it now. In for a penny, in for a pound and all that.

Looking at flea bay hydraulic pumps 187473M1 (order 184473M93) and there is a wide range of prices from around $225 up to over $400.
Why is this?
Is there a difference in the quality of the pumps?
I don't want to do this again anytime soon so I want a good reliable pump.

I should probably replace the PTO seal as well while I'm in there?
Anything else?

I need some advise on the parts quality and some recommendations.
 
I have never worked on a 1964 Massey 65 Diesel UNDM 704769 Utility:

I own a MF FE 35 X 1963 and replaced the HYDRAULIC pump as per the picture:

I am totally satisfied after 32 HRS running time:

I can not condemn the operation of the pump in any manor:

Note......

I checked all fittings on the NEW PUMP and yes some of the PIPE PLUG fittings were LOOSE.

I bought the $225 one on eBay and so far it is proving out ok.. I think they are all after market and most likely foreign made. Didn't check but I think price of a new pump from the dealer would scare you, and it is probably a foreign made one too. IMO
 
Here are some pictures of my MF FE 35 X that had a Faulty pump (5000 hrs on pump,submerged in water for 20 yeras):

Installed new PUMP,piston and ring as I was in the area:

Drive coupling was bad,changed out:

Note # of New pump....same # as YOUR POST...:

I rebuilt mine with a factory rebuild kit from AGCO. I don't remember the cost, but I read so many mixed reviews on the foreign made pumps at the time I needed one that I just opted to rebuild.

Besides the fact that I could have nearly bought a whole new foreign made pump for the price of the kit, I did learn a LOT about how it all works and I could easily rebuild the pump in a a few hours while being meticulous.

I even put it back together wrong and blew out all the o-rings. Remember when I said I learned a lot? ;)

You'll be fine with the $200ish price range pump.
 
Thanks to everyone who replied and many thanks to John Deere D for the pictures. That makes it look a lot simpler than I had envisioned from reading the service manual. To all appearances it looks the same as my tractor.
The service manual has a whole lot of servicing and inspecting that doesn't directly involve pump replacement. It had me kinda confused where to leave off and where to start on strictly pump replacement.

The strong back for the lift cover is a great idea. I hope to never to do it enough to really need to fab one up. I may whip up a simple one with a piece of plate and a lift ring.

As I'm looking at this, it appears all I have to do is remove the lift cover and its all right there. Pay attention to how the lift linkage comes out and make sure it goes back the same. Add a new PTO seal 195506M1 and I'm good to go.
Sound about right?

Shaeff, I thought about trying a rebuild. I've rebuilt swash plate pumps for excavators before, a real pain. But they were thousands new, not a couple hundred. I may try it to have a spare pump, but considering the age of this thing I'm not confident in the condition of the base parts.
 
a & i products has 184472M93 sugg retail $ 405 + s & h with warranty. repair kit A-1810678M91 suggested retail $ 24 + s & h
 
I got a new pump on order from flea bay for $240 and free shipping with a 1 yr warranty, plus a PTO seal for $10.97.
Not too bad for a little peace of mind. Hope I don't need the warranty.

Aside I had to buy a right hand tie rod end as well. Turns out the tie I had was a cobble, had 1" tie rod end on it. When that's done, the front end will be back stock and right as it should be

It's almost there.
 
I have done both a 50 and a 65 with rebuilding the pumps that I had. Not to bad of a job. You say you don't want to do this again soon? Make sure you fix where the water got in from in the first place.. The top link rubber boot was non existant on both of mine and the shifter boots were cracked as well. I also replaced the bushings on the rock shaft and the o ring between them. Just some of the things you want to check while you are at it.

All the boots were new on mine except for the rear top link boot. I didn't even know one went there until ptfarmer mentioned it. I got one on order. I'm also replacing the PTO seal while I'm in there. Its not leaking now, but it looks pretty easy and who knows how old it is. The tractor will be housed in a shed when I get it finished and moved to Mom's so I'm not too worried about water getting in after that.

John Deere D those rear end guts look clean enough to eat out of.
I'm a big believer in cleaning stuff up as well. Grit and dirt/stuff has no place inside a piece of equipment. I'll even paint stuff before I put it back on. May look kinda funny compared to the rest of the tractor, but its a weather protection thing as well.
Pictures are always a big help from someone who has done this before. I appreciate that. Thank you.
