green diamond Posted November 11, 2023 Share Posted November 11, 2023 Its a long time since ive had one to bits and parts were a bit more available then but now struggling with synchro rings, 1st have one part number, 2nd have another part number 3rd/4th/5th & reverse are the same, can anyone remember if they are all the same size and just the material is different which is how I seem to remember it? ive plenty of 2nd gear ones but no 1st and only a few 3/4/5&rev Quote Link to comment Share on other sites More sharing options...
611 Posted November 11, 2023 Share Posted November 11, 2023 Hey This might help. https://www.theopelproject.com/workshop-manual-sections/ scroll down and you will seer the 5 speed box section. There is a link to a BMW site that might help as they used the same box but with a different housing. Andy 1 Quote Link to comment Share on other sites More sharing options...

I used it for reference when i rebuilt mine many years ago. Luckily all my gears were ok and it was only bearings and a few other bit i needed to replace but handy to see how it all fits before you pull it apart 🙂 Quote Link to comment Share on other sites More sharing options...
