YANMAR 2002D TACH CABLE LEAKING

[winston1]

My 2002D tachometer cable leaks where attached on housing in front of engine. One fellow said the housing would have to be changed to stop this. Any other advice out there? Also wondering what John Deere would be closest match to this Yanmar? Thanks, Winston

It' really hard to tell from here whether the housing is bad or just needs tightening or thread sealant. If you need one, why not a Yanmar parts dealer.

You may need to replace the O-ring, it's an odd size. I should have a housing if you need that.

If it's that odd of a size you would be amazed what straight cuts to shorten it and a drop of super glue will do for you until you get the correct one. Most likely very little or alot of cases won't leak at all.

The parts drawing does not show an o-ring on the tach cable. I tried putting one on it with no success. Winston

winston , have you considered the gasket in a tube? you could also try Hoye for that housing. russ

I have tried a silicone gasket sealant after cleaning everything. May not be the best sealant for the job. If you know of one that might be better I might give it a try. I haven't tried to locate a housing yet. Figure it will be pricy and I'm hoping for a cheap cure. I've been called cheap before.

There is no O-ring on the tach cable, the O-ring is between the tach gear housing and the front cover housing. There are 2 nuts that the tach gear housing on.

It is leaking where the tach cable screws in. It is tight. I cleaned all the area good and put silicone gasket sealant all around it. Still leaks. Not leaking around the housing. Thanks, Winston

Spring for a $ 10.00 tach cable, if it still leaks replace the housing.

I suspect there is a seal of some type inside the gear housing. The cable housing is probably not intended to prevent leaks. Take a look.

Just wanting everybody to know I have a new tach drive housing, o-ring, and tach cable ordered. Will not remove the old one till new one arrives. Might want to do a little work before then. I will inspect the old housing closely and report back any findings of interest. Thanks for all the input, Winston

Recieved my new parts from Hoye this morning and got them installed. No leaks now! The little tach drive housing has brass bushings in it that the 2 shafts run in. I suppose thru about 26 years of running the clearance had gotton great enough for oil to come up thru the housing. Thanks for all the advice on this project. Winston
