Dual Remote Leak........Please Help

[dukeyjoe]

Posted this in the hydraulic section and have gotten lots of views, but no responses, so giving it a try here. Didn't mention brand over there, cause this problem has nothing to do with brand. I'm not even sure that this is a Mahindra factory dual remote set up. I would, really, like to see a pic of any dual remotes on the 5035, if any of you are so inclined. Anyways, I need to get some grass cut will the weather is good and am dead in the water till I get this fixed. Any help would be, greatly, appreciated! Below is a copy and paste of the thread that I started in the hydraulic section. Thanks in advance!

Well, we got some decent weather the last couple of days, so I set up the flail mower and was getting ready to go do some mowing, when I noticed some hydraulic fluid on the ground. After cleaning the oil off the tractor, I was able to isolate it. It was coming from the male threaded fitting off a square 90 on the front of an aluminum looking block, where the dealer put a second remote on. I could grab the hose and move the hose angle, with my hand, from 8 o'clock to 11 o'clock - at which time I ran out of threads. It leaked even worse at the 11 o'clock position. There is a bolt that threads into the end of that 90 and I don't understand what that is for. Could it have something to do with adjusting the tightness? I am over an hour away from the closest dealer and I bought this tractor from a finance company that repossessed it. The tractor has 8.5 hours on it. Any help from y'all would be, greatly, appreciated. I think my wife is going to go postal, cause she wants to use "her tractor".









Sorry, the pics are sideways.

I'm not exactly sure by your description where your tractor is leaking but I'll give it a try. If the bolt going through the square fitting is leaking then just tighten it up until it quits. The bolt is called a banjo bolt. If you look closely you can see a copper washer on both sides of the bolt. The copper washers are what seals the connection. If you over tighten a banjo fitting they distort and will not seal. Either replace the fitting (square block) or take a file and file both ends where the copper washer goes flat again. Also replacing the copper washers is a good idea. Any automotive supply store should have them.

If the fitting on the end of the hydraulic hose is leaking tighten it up. If that does not cure the leak then you need to remove the fitting and either replace the banjo fitting (square block) or the end of the hose. Any hydraulic supply place should be able to either cut the fitting off and replace it or make you a new hose if yours isn't long enough.

If the square banjo fitting is leaking and you can't find a replacement then you might be able to get a banjo fitting crimped onto the hydraulic hose and eliminate the square block.

Thanks for your reply. It appears to be leaking where that square 90 marries up to the stainless steel block. I can move it about a 1/4 turn by hand. Are you saying that tightening that bolt head on the end will suck the 90 elbow down tighter to the stainless steel block?

Edit : I, wrongly, assumed that 90 degree elbow threaded into the stainless steel block. Now it makes sense! I'm off to the tool store to buy some bigger wrenches It's bigger than a 26 mm and smaller than a 1 1/4, but the 1 1/4 did move it when it caught the points of the bolt head, so it is loose.

Yes I believe that is what he saying. You should not be able to move that by hand.

 

[dukeyjoe]

Roger that and thanks for the reply.

While tightening the bolt, use another wrench to hold the fitting lined up with where the hose sets in natural position. If the fitting rotates with the bolt tension, it will pull on the hose then over time the tension of the hose can work the banjo bolt loose again. Probably why it started leaking in the first place.

X1 for SSdoxie. Good idea. You just want to tighten the fitting till it quits leaking. Banjo bolts are notorious for leaking if overtightened.

Thanks for all responses and advice. When the wife gets back with the bigger wrenches, I'll tighten that banjo bolt up and let y'all know how it turns out.
SS, where abouts on the Cumberland are you? I'm right across Hwy 24 on Sand Mountain.

Well, no 30mm boxed end and 1 1/16 and 1 1/8 too small, but I did manage to tighten the Banjo bolt on the forward end with a 30mm open end and it stopped leaking. At first, it was froze to the 90 degree elbow. I had to break it loose from that using a 1 1/4 on the elbow, then was able to tighten it. I did notice another leak coming off the most forward line connection going into the side of the aluminum block. I tightened it down a little and it didn't leak. Then I went and mowed an acre and checked it. It is leaking again pretty good after the oil got hot, so I will tighten it again and keep checking it till I get it stopped.

How do the copper washers look. If they are distorted they will need to be replaced like pmsmechanic stated above. If they look fine tighten them a little more. If it continues I would take it back to the dealer.
