type 9 bolt pattern
hi been trying to measure the bolt pattern between the bell housing and the gearbox this evening, allow i have fairly certainly decided the distance
between the bolt holes, i cant work out the center on the input shaft relative to the holes.
i need to know this for so i can make a adaptor between the t9 and the 924 bell i have bought. its simpler on the bell, the input shaft hole is in the
middle of the bolts.
so i need a drawing or some info on the bolt pattern of a type 9
thanks stephen

might work, could try importing it into autocad and measure it using that using one known size
i bought the box without a bell which i think may be making it more difficult for me
did you use the photocopy to get a plate cut on the profiler when you made your custom bell owelly?
it could make a good article in ppc making bells and adaptors ete

Come to think of it, I may have that end on CAD.

perfect! i found that the dimensions seemed all be in imperial, how ever if well enough measured in metric will be good enough, as will locate
concentrically on gearbox spigot

i think this is from owelly's original pattern for the alfa to type 9

Yup. Those are my scribblings! I can't guarantee they are perfect but I've made three bellhousings, and a handfull of spacers and
they've all fit!!

Would you have a sketch of the Alfa side?
I'm trying to match up a T9 and Alfa Spider 2000 engine for my Marcos.
I've used punches to map out the Alfa side fairly closely but a proper drawing would be better.
How thick did you make your adapter and what did you do about the overlapping hole at the bottom?
My T9 has a cover over the layshaft retained by three bolts.
That cover comes up under one of the Alfa bell attachment bolt locations.
Does that cover mean this is a V6 box?
It was sold to me as coming from a Merkur.
At these fuel prices I want it leaded, five-star, and my windscreen cleaned!

The Alfa engine I used was the V6. I didn't make adaptor plates as such, but scratch built bellhousings. I may have a couple of bellhousing
photocopies tucked away somewhere but I doubt they'll be any good to you!
