Twincam Jackshaft wanted

[JonB]

Hi

On examining my Twink's jackshaft, I found one of the teeth missing on the gear that drives the fuel pump. Hurm. I think it is still usable, but I'd rather not. So, has anyone got a spare jackshaft lying around?

Thanks

I presume you mean the gear that drives the oil pump and distributor. The fuel pump actuating lever is moved by a lobe.

And just make sure that if you are offered a jackshaft Jon, that it is the correct one for a twin cam, with the right oil porting. When I went to look out a j/s for my current engine build, the first 2 I picked out were wrong, incorrect porting slots. Trouble is, I have had them so long, I cannot remember who I got them from, to wrap them round their heads, in a friendly kind of way.

Yeah oil pump, what was I thinking? Cheers!

@Les : that’s worrying.. I’ll stay sharp. Like I was when I bought the car

So, I thought this shaft was basically a camshaft off a standard 105E engine. That not entirely true?
