Question on MF 202 Power Steering

NCmau · Jan 18, 2013

There a leak from one of the banjo fittings in the power steering valve, Part# 1 751 875 M1. The thread that connect to the hose is somewhat stripped. According to the MF dealer, that part is no longer available. I emailed AGCO and they didn't even answer, so I assume they don"t have it. I can't believe that a common banjo fitting is non-existing. There must be a source somewhere. I did some googling but I didn"t come up with anything.

Can anybody point me the right direction?

If this part can not be found, is there a way that I can fix this thread? One solution I was thinking was to epoxy or braze an extension (male/female) to the fitting.
Maybe you guys have some words of wisdom.

Hi, can you post a photo?

Hi DavidP, thanks for the reply.
The fitting in question is the #1. Behind the bolt the fitting is 3/4" thick. I made an attempt to fix the problem by epoxing the extension adapter(#2) to the stripped fitting. The epoxy seems to be holding okay but it is leaking on the other end because the extension is a 45 deg. flare gas fitting and the mating hose is 37 deg. I had the brass extension on hand, so I figured I give a try.
So, I suppose the different flare degree and/or possibly the hose fitting are damaged.
I would much rather find a source for a new banjo fitting, but if I have no choice, I'll use a suggested practical solution that is better than mine.

I googled hydraulic banjo fittings and came up with tube-gear.com which looks like it has similar looking fittings although I am not sure if they would be exactly right for your needs.
Too bad they were all broken off of my 202 because I removed all the old factory stuff when I put together a fully hydrostatic power steering system for it. I will have a look to make sure but I am pretty sure they were all snapped off at the valve body.

Yes Inno, I googled that site and plus many others. I didn't realized there are that many shapes
of banjos, some even look like commodes.
If I am not mistaking, the JIC-06 (nominal 3/8") has a male thread of 3/8"-18, which is the
same for 3/8 pipe. Even though the pipe has a taper, I'm still not sure if I can use it for the JIC
fitting as well.
It would be great If you do have a usable banjo fitting. I'll be more than glad to take care the
expenses. I love my 202. It did have lots of issues, but little by little I took care most of them.
Can you give little info on your fully hydrostatic power steering? It is interesting as much as
expensive. Please email or post it. Thanks.

With all the parts my 202 needed to make the power steering work again I figured it would cost me well over $1500, many of the parts would either be used or have to me machined and fighting with the original fittings as you are doing didn't seem like a good option.
This was a few years ago now but I think I spent somewhere around $500-600 for everything. One thing that reduced my cost a great deal was a great deal I found on E-Bay for a used Char-Lynn power steering valve. For $135 I got the valve, steering shaft, steering wheel and 4 6' lengths of hydraulic hose.
Here is a link to a video I made explaining some of it.

Just re-watched the video, the answer to the above question is in there, all the fittings look to have been broken off.

Inno · Jan 22, 2013

But wait...I had a look through the box of parts this evening and here's what I found...

NCmau · Jan 23, 2013

Inno, It looks like exactly what I need. The one I need the most is
3/4" thick and the other one (7/8") I can use it too.
Shoot me an email and let me know how much you want and I'll be
happy to oblige.
Thanks.

Well gosh........they're rare antique parts......discontinued and all..........

I have no use for them and you are a regular here who contributes to the community. I'll send them to you for the cost of shipping which shouldn't be too much.

You are a great guy Inno. Give me an address and I'll send you the
money. My address:

I had all 4 of those fitting leaking on my 135. I could not find them at all. The problem i had was they were over tightened and the sealing face was destroyed.

3 of them that had good threads i chucked them up in a 4 jaw chuck in the lathe and re machined the 45" sealing face and they sealed like new. There was enough thread to still tighten up no problem.

1 of them had stripped threads. I took the original fitting, Chucked it up in the lathe, faced it off flush, Drilled and taped for Npt. Then got a NPT to SAE 45* fitting and installed it with loctite. Now the NTP threads were protruding into the hole where it attaches. I set it up in the lathe and bored the inside to be a perfect match to the existing bore. Worked great and no leaks.

I might can dig up pictures if you need them.
