12V generator with single port cylinder tin problem

[HenrikL]

I have read lots of posts on 12V conversions, but this was an issue I 've not seen before. The generator interferes with the cylinder tin and does not seat in the fan housing.

What is the best solution for this? Grind off some material from the generator?

Are you using a 12 volt fan shroud? I have the original early single port tin (no fresh air hose hole) and didn't have any issues.

I had a 12 volt generator on a single port 1500 S engine and it fit fine. I've since swapped to an alternator so I can't be of any use with photos.

Did you align everything in the front? Make sure the pulley and belt are correct, then check again. It looks like the generator is not in quite the right position.

Mine dropped right into place after the fan shroud and pulley cover were swapped to th 12 volt version so it's a bit odd that yours doesn't fit.

I found a couple of photos of my 12 volt generator on early single port tin...

Zero modifications to the tin.

Thanks for the pictures. I will have a good look at my engine next time I'm in the garage.

I have to agree with everyone above, in that something is off with your tin. Here's a pic of my 64 T-34 engine with a 12 volt conversion (gen and big alloy shround). If you look closely, I'm even using the early style belt cover (bolt on).

Winter is finally over here in Sweden and time to start working on the Type 3 again.

Those of you who have done this conversion, do you use the 6V (96 mm) or the 12V (100 mm) generator pulley?

Back to work on this task. It seems as if I have to move my 12V generator 15 mm forward before the fan belt lines up. No way that is possible with my current cylinder tin.

I compared with a 1963 tin in the pichure below. Note that the 1963 tin has a much larger room for the generator.

I don't want to butcher my original tin. I think the way forward is to fins another tin and check if that one works better. If not it is time for some welding.

There seems to be different versions of the single port cylinder tin. Compare the tin in the picture below (taken from classifieds) with my 1964 tin a few posts up. The room for generator is much larger than my tin.

I wonder if the factory changed the cylinder tin when the new exhaust was introduced in 1964?
