K1100 16V Turbo build...now transmission build.

lovely neat job on the support pegs matt.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

I've got to say, I'm seriously impressed with this project. I'd love to have the engineering skills to even contemplate something like this, never mind achieve what you have

Thanks for the comments. :)

Ive been busy trying to get some work done on this, slowly but surely things are starting to fit together. :)

I reamed out the centre bearing location and shrank a bearing retainer in place, this will give something for the bearing to locate on, and hopefully make it easier to remove the bearing without destroying the casing.









bearing for selector drum now fitted.



Selector drum nose support bearing and housing.





The next part to make was the centre web plate. This plate will retain the mainshaft bearing, provided a location for the reverse idler gear and selector mechanism, and a place to fix the input shaft thrust bearing to.





All getting a bit tight for space this end!

Wow

Wow squared.

Matt, can I see the finished product before you install it ,please ?

Let me know when you are ready.

Amazing work! Ready for MITP?

Ow yeah Matty, new pics! It look the recent bad weather helped you to make progress and not be laying on the beach
Great to see the centreweb plate being one part with the original pressure plate for the mainshaft bearing. Will your idler gear for reverse have constant mesh with the input shaft?

I hope to get my shafts in July. In the meantime I also had to keep my wife happy, so I spent some time rebuilding a kitchen, no big steps here.

gogo!, regards, Bart

Top quality workmanship
Take a bow that man.

-MINI CLUBMAN 1380 TURBO-

Thanks for all the comments, is looking increasing more like it'll work day by day, I just hope it copes with the power.

Dave - yeah you're welcome to come and have a look any time

Carl - haha I wish! Castle coombe is my aim but we'll see. It was coombe 2011 the last time I drove it so need to pull my finger out.

Streetscreamer - yep idler gear is going to be in constant mesh with input shaft and be 2 gears on one shaft kind of similar to the standard mini reverse gear.

Blimey. That almost looks like it'll work.

Fantastic job Matty.

In the 13's at last!.. Just

I'm not too sure on the gearset, i got it second hand, that seems fine to be honest.

The bearings and layshaft on the other other hand...the last one was in for 300 miles and its now only worthy for the bin the one before that didn't last long either once I turned the boost up. Lol

Holy shit .

how are you getting along with the 2nd box for me matt?

Haha it coming along nicely. :)

Just looked at your bulkhead inside the car. Are you running a rollcage/dash bar? Is there any need to stiffen that part of the shell back up if not? And if you have how have you done it? I want to tidy up my bulkhead and my lower dash rail is mashed up and I'm fitting a curley carbon dash so I want it out.

I've used slightly thicker steel in the bulkhead panel, and where the horizontal and vertical panels meet there is an L section piece that is about 2mm thick.

I'm not running any kind of crossmember on the roll cage at the moment. I've read many places that the top rail is structural, but if it is I'm confident that my replacement strength is enough.

I would of kept the top rail if I could, but that would mean that the join between the new bulkhead panel and scuttle wouldn't of been as strong.

Thanks bud, I'm keeping the top rail anyway anyway so that's not a problem. I'll look into mine when I start cutting all the crap out.
I'll have a 6 point bolt in cage on mine anyhow. Awesome looking build too as always :)
Bet you're looking forward to testing out the gearbox now it's so close to completion!

Yeah it'll be a nervous moment testing it! Lol but looking forward to it.

Ive nearly got the selector arm in now, will upload some pics.

Does anyone know how I tell the difference between A and A+ gearsets? I need to order a new 1st motion bearing but I'm not sure what type it is. I also need to order a layshaft needle roller bearing, but I'm not sure what gearsets that was from now either. Lol all I know is that the id of the layshaft is 25mm?

Righty bearings all sorted now.:)

Some pics of my weeks work.



Selector indexing wheel now fitted, and carrier made up than runs through the centre web and through the needle roller.



Boss welded onto the side of he box, for the selector arm to run through. This will eventually have a needle roller and obviously an oil seal too!

Good progress, good pics Matt!

Interesting to see your solution for the selector arm. It looks it is not mounted straight up but under an angle, just to have enough space for the swing?
Still planning to control the selector by electronic way?

It is also my plan to have some welding in the corner of the box where your selector arm runs through, but just for mounting a position sensor.

cheers, Bart

Matty,
Great stuff. Thanks for sharing this with us all. So, did you think it was going to be this much work LOL? And would you have started it otherwise?

BTW 99.9% of the A+ gears are all single groove. I recall the two-groove A+ gears are the Metro HLE close-ratio gears.

Bart - yep you're correct, if it was mounted directly below the drum their could shift down but not up, by moving it round 10-15mm it's got enough room for shifting
up and down now...I hope! :)

As for shifter, I'm not going down the electronic route anymore, but I'm in progress of making the shifter "solution" to test out the shifter mech in the box.

Dave - haha I thought it would be a challenging project, but I didn't realise that everything would effect everything else...you move one part in the casing and everything else has to move with it, lots more spacing issues than I had originally thought too! But if it all works, it'll be worth the effort.

This is brilliant, hats off to you Matty. I bet it's so frustrating refitting then removing the gearset everytime. It looks brilliant thou man, it'll all be worth it I'm sure!
