ital engine rebuild

Post by **spotdoc** » Wed May 17, 2006 9:01 pm

can anyone help me?
I'm trying to fit a modified 1098 flywheel (from ESM) to an Ital 1275 engine.
The flywheel has a spigot which won't go into the "hole" at the end of the crank. There is a bush and a roller bearing that prevents it from locating.
Is there something I'm missing?

thanks for any advice,

Makes no sense to me - main problem usually is that 1275 fwheel has 6 bolt fixing + dowels, and 1098 has only 4. And only 2 of the 4 will line up with the 1275 crank ! So you need to drill 4 more holes - very accurately !! The bush + bearing thing must be an ESM mod - so ask them !

Roller bearing bush is there as a modern replacement for the bronze-ey bush in the Minor crank. Sadly, it is the wrong size. Pull that sucker out and slide the minor one in. To get it out of the minor crank just slop some grease into the hole and then whack the end of a rod in there with a hammer as a plunger to hydraulic the bush out.
(I last did that about a decade ago, but I think I've got it right)

In the back of my mind there was (possibly on the Maestro crank) one of the drive spigots offset from the normal position plus the Meastro crank doesn't have any sort of gearbox input shaft bearing in it.

Are you instead talking about a Sierra 5-speed modified flywheel and spigot bush adaptor?
Can you post a picture?
