Tachometer problems in cold weather

[DJRussell]

Hello all.

I have a GC 2610, approximately 450 hours. Have owned it since Spring 2013. Tachometer worked flawlessly in the spring and summer months. First cold day this fall, it acted up and the rpm's indicated over 3000, even when barely above an idle. Shut it down, and it worked fine. That was with the temperature about 45 F. Today the rpm's indicate over 3000, actually the needle was buried, and made a whirring sound.

Has anybody out there had this problem, and how did you solve it?

If I have to, I would be willing to disconnect the Tachomter for the winter, to save it for the summer when I really need to monitor the rpm.

Problem is, I don't really know how to disconnect the tach.

Any help would be appreciated.

Regards

Jim

Apologies to all. I have now searched the forum and saw a thread by rjmack, describing exactly the same symptoms. I will simply cover the vent holes in the hood, and if no joy, then disconnect the cable for the winter. I don't want to destroy the tach. Don't really need it for pushing snow, but sure need it for mowing and backhoe work.

Regards

Yes mine was doing the same thing last year. I covered the vents on the hood above the thach and it has not done it since .Many on here have mentioned the same problem .

I tried covering the holes, doesn't really do much. the problem still exists and I am wondering how long it will be before the spinning end of the disconnected cable wears a hole through something important in the dash.

massey ferguson obviously doesn't give a hoot about their name anymore. if there are any lawyers in the crowd, I would be happy to sign up for class action.

you obviously don't own one of these.

No I don't.

Long time ago when vehicles had speedometer cables they used to act up as described. Oil did work for them.

Graphite would be much better than oil on a spedo or tach cable.

There is a design defect here, and lubrication has been tried.

this is the problem.

Massey Ferguson Tachometer problem - YouTube

you can see in the video that I have the vent cage stuffed with plastic grocery bags to try minimize the cold air across the tach. I just thought today of taking the radiator screen out and putting a piece of cardboard or plastic in there and try that.

This problem does not occur in warm weather, but it was barely below freezing when I took this video, when it gets cold you can hardly bring the rpm's up at all.

Still glad mine doesn't have a tach. :thumbsup:

Finally switched computers and watched the video.

Sound just like the old speedometer cables and acts about the same but with much less swinging.

Suggestion if possible: run tube back from front of engine and use a 12 volt computer fan to blow on the tack????
