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

New engine mount, how's it's looking at the moment. I'm looking at adding a crank trigger bracket and possibly incorporate a cam sensor bracket onto it too.

Thats a beutiful engine mount!

Nice work!

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Nice engine mount, how did you make that? Did you make it in 3, then weld it up?

Team www.sheepspeed.com Racing

Yeah, made it in 3 parts then just welded them together. The edges of the plates were positioned so the weld was a fillet instead of external corner if that makes sense? It made it easy to blend them as I wanted it to look like its not lots of parts welded together and more factory looking.

This thing is a work of art!

In the 13's at last!.. Just

The bearing retainer is sintered steel giving the impression of being cast. To a degree I suppose it is cast, but then to a degree it is also forged

Team www.sheepspeed.com Racing

Yep looks exactly the same, although I made yours out of lead for a nice bit of ballast.

That engine mount bracket is great mate, similar to my titanium one

I seriously doubt it!

Happy to read the steel welding went fine, Matt. I will continue with that too. Here is the draft of my plate now (size is related to the available material)


For the reverse gears I will not use the bike gears but original mini gears.
Even the shift fork will be made out of old mini bits:


About the grinding I will have a try first to DIY, I have some old bits left for trail.

regards, Bart

Which mini gear are you using that needs the splines grinding out then?

Thanks for the comments on the bracket. Unfortunately I don't think most of it will be visible when the engine is fitted and all the gubbings in place.

Paul - I've been toying with drilling some progressively small holes down the centre of it to save a bit more weight. It all seemed a bit flimsy until I welded it together. I reckon I could of used thinner material in hind sight. I'm going to drill one holes at the bottom at least, to let water drain out of it.

I dont see a problem with progressively sized holes aslong as theyre deburred and finished nicely like the rest of it

I seriously doubt it!

Matt,

The grinding will be for enlarging the hole in a gear which will be shrunk on the back of the lowest one of the drop gear. For imagination see the pic below. The dropgears will be straight cut by the way. The helical one is just for the pic.

Ah I see, I thought it was for reverse gear.

No need to shrink it on through, as 2 gears do fit on a single shaft. Besides I wouldn't rely on just a shrink fit for any gearbox gear, it is likely to come loose. Have a measure up of a gear and and the boss, with a bit of trimming you can get 2 to fit.

I'll post a pic of mine when I get it back, it's just at the gear cutters at the moment as a sample gear.

Oh yeah, you'll also have to elongate the splines on the 1st motion shaft, as you will have to remove the under cut from the inner gear.

It will not be shrink fit only, there is some room for a TIG weld too.
I don't exactly understand yuor second remark about the undercut, but the housing of the gearbox is trimmed to create space for the extra gear.

The two standard 1st motion gears have an undercut/counterbore at the end of the boss to clear the splines on the it's motion shaft where the cutter has ran out to the inner bearing diameter. If you remove the boss from the gear, then it doesn't butt up to the bearing, unless you relieve the splines. If that makes sense?

As my workshop has all been packed up due to moving, I've been cracking on with this during my breaks at work.

This is the piston assembly all made for the reverse gear, it's taken a fair amount of thinking about as space inside the box is becoming non existant in the pinion side.

I have also machine up the reverse gear support which also has the cylinder this all fits into. Will get a pick when I've finished machining off the excess material. My engine mount is now all dowled in place too.

I've just got the linkage to make now, to join the air cylinder to the reverse gear selector and amazingly that is every component finished. So it'll just be a case of finishing tidying up the casing, and setting up the shifter cylinder.

oh thank god for that.... assembled for new year ?

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

Probably not, I'm moving house next week so I've got weeks of the usual DIY and sorting the new workshop out.

I'm hoping to have the engine and box fully built up at by the end of feb, after some testing on the box. I need to bench test the shifter mechanism on the box first to make sure it shifts correctly. Oh and make the shifter for the car. Lol

Well after two weeks of no Internet I can update my progress!

My bearing support/air cylinder is all complete. I have a video of it working but unfortunately I can't seem to transfer the file onto my iPad. It's an mp4 format if anyone knows?







I'm in the process of cleaning up the gearbox casing now ready for the new bearings to be fitted, and hopefully the final build. I've made a boring jig for the transfer housing, so over Xmas I'll bore the transfer housing for the support bearing. I've also had a call to say my new input gear is winging its way to me, so thats the final piece of the jigsaw I've been waiting for...fingers crossed it fits ok!

I've decided to press on and get the car back together now, and once everything is tested I can get on with lightening all of the parts of my list.

It sure is, my new input gear arrived today too.

Dan - I don't suppose you have an old 3rd motion bearing knocking around do you, that I could borrow?

I will have a look for you tomorrow mate, is it for mocking up purposes or does it need to be in good condition?
