Hi Guys. Been working on the D7 off and on and come to realise it's time to pull the steering clutch controll and reseal it. It's been leaking a very small amount of oil threw last winter but has now growen to a annoying oil leak. There's a steady drip now.

Just wanted to check and see if it was posible to reomve without pulling off the fuel tank or if it's just not worth the hassle of fighting with and just remove the 4 bolts and one fuel line and be done with it?

Also how complicated is that little valve?? Looking at the parts diagram it doesn't look all that bad but if I open it up are there going to be springs flying out at me in every which direction??

Thanks in advace for the advice and tips.

Ryan

It, should come out okay. Just need to get the bolts up 1/2" to get valve loose and slide it out with them in it. Take it apart slowly so you keep track of where everything went. A piece of plywood with 2x4's around the outside would be a good work bench to keep from loseing parts. You will not be able to get the tubes going down inside out to reseal with tank on I don't think. Clean all around valve before you start to keep dirt out.

Don't think you can get into much trouble...there isn't much in there.😊
Service manual does recommend removing the fuel tank, operator's seat and steering clutch control rods.

Shaft removal is a little dodgy.
1. loosen the bolt clamping the lever to the shaft.
2. remove pin from shaft.
3. drive shaft to the left to force the plug out of the housing.
4. drive the shaft back to the right until the lever can be removed.
5. remove the key that held the lever to the shaft
6. drive the shaft out through the left side of the housing
Repeat for second shaft.

It's probably the shaft seal that is leaking and more than likely it is grooved and pitted requiring "speedy sleeve" repair

Om, that's what I'm a little concerned about that the shaft may have some damage on it. Hopefully nothing that can't be fixed with a sleve and some lock tite There's also some side to side play on it for some reason. It's not holding it in tight like the left side hydraulic controll is. It's the front shaft of the control that's giving me grief. Seems to me it's the right side control.

Thanks for the info Bob, I kinda though it'd sneak outa there just eyeballing it but I didn't know what all was underneath it that might come up with it.

I just had the compartment all washed out so that I could check things out. I think I musted of pushed something loose because it seemed to get worse now afterwards. Got a few other little leaks here and there to fix up and then she should be good as far as leaks anyways. Then it's onto other things. Never ending battle it seems.lol.. As long as it's things I can see from the outside though I don't mind it to bad.lol..

Thanks guys. Might be a little bit before I get to this job. Just about to start harvest here. Just trying to get my ducks in a row so if I get a rainy stretch I can put it in the shop to work on. It doesn't work everyday so I've got lots of time to fix it. Got some jobs that I could be doing with it, but it's not a priority right now unfortunatley. Can't wait to go play some more with it though. Always the fun part of having these toys.lol..

I'm having a pressure problem on an old d7e for the steering clutches. I have about 180psi at the pump. Can anyone help me please?
Thanks,
Tim.
