Hello
A friend of mine has a 1936 Morris 8 4 seat tourer with a 3 speed box and has just bought a four speed box from a series E. I seem to recall that this was a commonish conversion years ago, but I cannot find anything on the internet about it. Rather than trying to "reinvent the wheel" I wondered if anyone on the forum had any experience or advice and tips.
He wants me to help him, but as he is older than his car, I may be doing most of the work! Smile
Thanks

Hi

Yep its still a popular conversion, if your mate is in the Morris Register, there is an email forum, where this topic is often raised and advice give.

Basically there are 2 challenges; firstly the rear gearbox mounting is different, I recall that Austin 1100/1300 subframe mountings provide a suitable fix. Secondly the input shaft is shorter on the 3 speed box; on the 3 speed box the shaft is supported by a bearing in the flywheel, on the 4 speed its a plain bush in the end of the crank, its a simple job of removing the bearing in the flywheel and tapping an oilite bush into the crank.

Hope this helps

Dave

Thanks, that is indeed very helpful. I have looked at the Morris register forum and can find no details of this swap at all in the members area?
Perhaps I am doing something wrong? - The morris 8 section only has 80 posts.
Once again many thanks

Actually - after more looking - found the past copies of newsletter section - full instructions, and with diagrams - what a really good club website!
I wish all car websites were as good.

Hi there is a email distribution group/forum (8MVS) this is where most of the discussion takes place, the forum hasn't been widley acepted yet. There is a link on the main site to join the email group.

Cheers
