Oil comming out of Tach Cable input

Noticed oil on my pipe, dripping, then noticed the sscrew on the tach cable where it feeds into the motor was loose, is there a o-ring or is it just loose? Help please.

 

Here ya go: http://xjbikes.com/Forums/viewtopic/t=19538.html it's in "XJ FAQ Suggestions" along with the rest of the how-tos. Everything you need to know.

There is an oil seal inside the drive body, and a PROPRIETARY, D-section "o-ring" on the outside. XJ4Ever and Yamaha have the correct parts; don't trust eBay. An O-RING o-ring won't work, you need the stupid D-section ring.

 

Once tightened, it doesnt seem to leek anymore in neutral. Wonder if it was just from it being loose?

 

Nope. It's because all that stuff is 30 years old. It used to get hot, then it sat for a long time and dried out. Now it's not so flexible any more.

Both of mine started leaking within a few hundred miles of putting the bikes back in service.

The repair isn't in the books, which is why I did the piece. Save it, you're going to need it sooner than later.

 

ok thanks alot.

 

Be careful. If it's puking oil bad enough and you keep the ferrule tight, you can end up with a tachometer full of oil.

 

Yeah, ive never messed with that before, i did tighten that sleeve down though. Guess she's out of service till' i get that fixed!

 

It's not THAT drastic; just don't put it off. No need to pull the bike off the road for that.

 

its incredible I stumbled upon this tonight! ive had my nose buried in my manual trying to figure out what in the world that is that oil is leaking from. the PO stripped this bike to a bobber status. needles to say, the tach was probably the first thing to go lol. the tach bolt is located directly under the timing chain tensioner correct?

 

Umm, no. The mechanical tach drive was located on the right front of the head on the earlier aircooled bikes. The cam chain tensioner is on the rear of the cylinder block.

Your bike never had a mechanical tach. It was electronic.

More likely than not, if you have a leak in that area (not uncommon) it's the cam chain tensioner body-to-cylinder block gasket.

Are you referring to the head of a vertically-oriented bolt on the engine casing just below the back of the cylinders? (The head would be "laying flat.") THAT bolt is the lower mounting point for the rear cam chain guide; DO NOT remove it.

 

ahh, I was hoping I had stumbled on a gold mine here. I will post a picture tomorrow. it looks to me like you have to remove that bolt in order to get the chain tensioner housing off. due to the fact that there is a cut out for the bolt in the tensioner body. is that factory or a bandaid from the PO?

 

you will have to forgive my ignorance regarding motorcycles, locations, and vernacular for the time being. I work on semis, so bikes are a HUGE departure from the norm.

 

Don't fret the gold mine, we can get you squared away. A pic would be a good start.

Might want to start a new thread since we know it has nothing to do with the tach drive housing your bike never had.
