I have a New Starter ready to install. I have also fitted a new Starter Jackshaft Kit. Unfortunately the long Jackshaft Bolt which screws into the threaded end of the Jackshaft does not fit.The NEW Bolt appears to be a slightly larger dia.
I am thinking that the new Starter is for a different year of Evo hence the Bolt not fitting. Once again any advice much appreciated. Bungo

 

I think there are three different bolt threads used on different years...you might want one of these...how many teeth do you have on the gear..should be 9 if it is stock and the correct kit

Some of the 89-93 kits come with 2 bolts

Hi, (Pic.2) NEW Starter/Shaft ....1.1/16". Long. (with slot for Circlip.)
(Pic.3) OLD Starter Shaft .....1.1/8". Long
Both 18 teeth.

 

Older starters 89-93 had 1/4-20 threads in the shaft where the bolt screws in...newer starters had 10-36 threads...the adapter bolts allow you to use a newer starter with the older jackshaft setup...here is another one.

Yes,Pininon Gear has 9 Teeth. Can you tell by looking at my pics whethrt my Starter is for a later (than 91 model)
If I do have to fit an Adapter Bolt will I then have to fit a Retaining Ring on the Shaft.?

 

Thanks Tom & others. Sourced adapter bolt. Bungo
