NH TN65 Broke Remote

My 2001 NH TN65 hydraulic remote stopped working. I was using the remote to connect a top link for a box blade. I would appreciate any insight into the workings of NH remotes before I tackle this problem.

Bob unhook both hoses then re connect them. Most likely just do not have the hose completely connected. If that does not solve the problem. Answer these two questions, does the three point lift come up when lever moved? When you move or hold the remote valve lever for a second or so do you hear the engine load? Please post you findings.

Tnx. for the reply! yes the lift works normally lifts the box blade and hold at any increment. The engine loads greatly when the remote lever is operated.

O K the fact that the engine loads is good. Now we just have to find the problem. I still suspect on of the quick couplers. Very easy for the coupling to not be pushed all the way in. Do you have another hydraulic operated implement or cylinder you could try on the remote?

I think jm is headed in the right direction. It sounds like a remote connection problem to me too.

Now I remember! The problem may be me. I did replace both hoses on the cylinder and maybe the connectors were not exactly correct. I will check out the connector ends tomorrow. Thanks a bunch for the diagnosis. I must be getting old and forgetful I'm only 78. 🙂

Bob at 73 and 35+ years messing with those things , bad connection has been the culprit many times.. You are not the first one won,t be the last.. Please let us know what it was.

First off, Wow! I can't believe I'm on page 14 of the Tractor Talk Forum, this forum is certainly busy and well staffed. I purchased new connecters for my TN65 remote hoses at the local farm co-op and had trouble getting them to operate, then I purchased some supposedly gen. NH hose connectors. I then measured both the local's they had a tip protrusion of 2/32" and the genuine NH's had a tip protrusion of 4/32" and were of different diameters. I will admit I am not a fan of hydraulic remote connectors. It does mostly work if everything is perfect. I still had problems with the NH remote female jacks leaking and the O rings to replace are very difficult to find, the best I can tell they are 13/16" ID and close to 3/16" dia. IF the O rings are a bit "fat" the connectors will not latch up and without the rings they leak terribly. The double valves in the connectors are difficult at best in that they have to fully open when connected to permit free oil flow. It seems to almost defy Pascal's Law of Hydraulics if everything is not perfect so the oil molecules can flow unimpeded. At Any Rate, the Forum was right be "Suspicious of Connectors". Finally my class 2 toplink works ok. Thanks again, great forum, [email protected]
