Tach Drive

[Guest]

So... replaced tach seals and cable, as well as fork seals, etc...

During the 6 miles to fuel and then work, the tach stopped working. I went home at lunch, pulled off the cable, it's good. However... the tach drive shaft that mates to the cable is broken off the gear.

I buttoned it up tight so as to not replicate the leak I was "fixing," and obviously need to get a new tach drive gear. I suppose i'll replace the seals also, but... is ther a commonly known cause of reinstalling this gear that may have caused this? Something I should watch out for when I reassemble?

Thanks!

You must have put it in a bind somehow to snap it off like that. Was it difficult to install? "Normally" it slides right in, I think it rotates slightly as it goes in.
Was the cable difficult to slip on? That was a significant bind in order to snap it off that quickly.

Went right in real easy; just like you said... Slips in, rotates slightly. Cable goes on, no real bind, made sure the slot in the cable lines up with the tab on the shaft.
things that make you go hmmm

Hi babes.
Hmmmm.
Yes, be carefull though as the worm drive on the tacho drive meshes in with slots on the exhaust cam shaft so make sure the tacho drive is complete and that nothing has sheared off into the cylinder head...

That is a good point, Seana23. RickW, I would go ahead and pull the valve cover (I know, I know) and check out the camshaft. The last thing you want to do is damage that bumpstick. Or use a damaged one.
