These are some photos of the crank I made.
[ Edited on 28-12-2005 by dangerous ]
It had Porsche rod journals and Type 4 mains.
I initially fitted to a water boxer case but it was a tight squeeze as far as the cam was concerned...
So I made this billet cam and had it hard faced.
It had a 1" base circle and was 16mm between the lobes.
The WBX lifter bores are very tall, so thre was lots of support for the lifter.
After destroying 10 rear main bearings that I had made out of Aluminium-bronze (with as much as 10 thou
clearance to stop the gauling), I purchased a Pauter case and then proceeded to chainsaw it in half with a pair of
broken Carrillo conrods.
So after regrouping, I got a set of Chev Carrillos and narrowed them to Porsche width. The crank was ground
down .006" to a .020 Chev large journal size and I was all set.
As you can see, the Chev rods have the bolts installed from the cap side.
This would normally interfere with the cam, but the Pauter case has a cam position that is 6mm
lower, so the clearancing was no probs.
It actually enabled me to check the rod bearings through the lid without other dissassembly.
OH! SORRY ABOUT THE CRAP PHOTOS!
Hey Dave
these pics and info you're posting up is really interesting

How long have you been playing with vw's
cheers

thats sweet as, how did you machine the rod journals?
Got into volksies as a 13year old kid in 1982.
Rod journals on this crank were milled into a square and then made round in the crank grinder.
My latest crank was done in the lathe using a special jig that held the crank at the correct stroke and I plunge
cut with a special parting tool til the journal was round.
It was then finished in the crank grinder.
In the process of trying to dial in my chassis car I went for a squirt down the return road and I backed off in gear.
This action sheared the wedge mate and the back of the crank was trashed.
This flange conversion worked very well and I have since done it at work for a customer....of course the bearings availability is an issue but we have
that under control now too.
The pauter case uses a propper bearing for the thrust, and in a Volksy case, separate split thrusts can be fitted from a Toyota.
