Any diesel gurus on here?

[d_x20 at hotmail.com (Bryan Rankin)]

I'm putting a diesel crankshaft into my 3a block.  It's already been fitted 
and etc, but now I need to get a crank gear that will fit onto there.  The 
diameter at the end of the crank, where the gear is bolted on is 31.50mm, 
but the inner diameter of my crank gear is only 22mm.

Does a diesel engine have the same crank gear as I need for my timing or 
will I have to get this crank machined down?


Thanks
