1896 remote problems

Thad · Aug 2, 2012

I have a 1896 that a guy brought me with one set of remotes weak. The other set is fine. I noticed several orings and such in the parts breakdown. I havent messed with to many of the remotes and dont want to take it apart unless i have to. So anyone had a problem like this before and what fixed it? Or have any good advice on what i need to do. Thanks Thad

Hi Thad, there was a posting on a similar problem a week or two ago, search for 2090/2390 hydraulics in search and check out the replies to IHmanky's post I think you should get a good idea of what you need from it.

hey Thad you might look at the back side facing the trans there is a flat screw driver slot remove this and see if there is a small o-ring gone, this should be a nylon on the 96 series o-ring on the 90 series but it might have been changed,i have more trouble here than anything,i guess the other remotes test ok?

I pulled them off and indeed one screw has a tan colored oring that is cut. The older post refers to that same area. Thanks for the tips guys. Thad

The tan color would signify that the o-ring material is probably not nitrile (Buna), neoprene or Viton they are usually black. The only tan rings I have seen were epychlorhydrin (probably not spelled right). My guess there is something in the TCH that could adversely effect nitrile, but Viton should work in that fluid. 'Bout the only thing Viton doesn't like is water, especially hot water and some amine based corrosion inhibitors but you usually don't see these in commercial hydraulic fluids. Also, Viton will take temps to about 300-350F.

There are also Orings under the screw plugs that must have the bottom spool caps removed to access them, might as well do them all while the valve is on the bench. Best to get OEM Case rings instead of generic IMHO.
