Thanks for taking the time to make these they are very detailed and clear and have been of great help in understanding how this car is put together (or rather taken apart) 👍.

Good luck Ryan, might be a valve not seating correctly or something simple. The R50 is lovely to work on. I'm far fonder of the Gen 1 than the later models. Thank you for watching them and hope they help.

Thanks a lot for the video. It's the only one showing a r50 Midlands teardown I could find. After trying to get to the bottom of a bearing noise coming from the clutch or transmission of mine, I'm considering a rebuild of the transmission to replace the bearings that most commonly cause issues. They seem to be the 2 just below the 5th gear clip (though in fact it might be the clip themselves) and the bearining just behind the clutch release bearing. Do you know how hard/risky it is to replace those bearings? Especially can you replace them without special equipment? (especially without a hydraulic press). Thanks!

Hello sir is it posible to use a 5 speed getrag in place of a midland five speed? On 2002 r50

@CoatsandGaiters Жыл бұрын

I believe it is as a lot of people do a conversion to the Getrag, I think you have to change other items though as well. It's not quite as simple as just changing the gearbox itself.

I'm glad I managed to find a video that can get me started. Mine makes bad bearing-like noises when the transmission is under load (giving it gas in 1,2, or 3 will cause this) and I'm thinking it's the input shaft bearing. 1-2 synchro also seems like it's worn out as well, and reverse makes a clanking racket. I'm in the US and I've found no one so far that actually rebuilds transmissions unless it's an "American" car. Even the MINI dealerships just tell me they would replace it with a new one, which amounts to $5200 out the door. It's pretty disappointing really. Do you know if the Getrag 5 speed from the post-2004 is a direct fit? Perhaps I can source one of those in good shape.

@CoatsandGaiters Жыл бұрын

Thank you for your comment. My black mini on my channel had the Getrag and I removed that to do a clutch rattle. They are a direct fit and a much better gearbox as the first one or Midlands Gearbox was weak and did explode when pushed hard. I think gear linkages etc might be different. In the UK most enthusiasts change the gearboxes to the Getrag so it can be done fairly easily I believe. Here is Part 4: kzfaq.info/get/bejne/qa-ImrN1rNXYk4U.html&feature=shares

@MaxDad7 Жыл бұрын

@@CoatsandGaiters Thanks! I’ll definitely do some more research. I know the shift linkages/cables were changes to have metal ends instead of the plastic ones like mine do. I know a lot of enthusiasts changed them to metal as most broke if shifted too hard. Idk if mine were changed or not. If the Getrag 5 speed winds up being a drop in then I may go that route for the better reliability.
