As the space was so tight under the ac compressor I had to drop the engine to get the water pipe from the header tank to the center tunnel connected, the the stainless pipe cleared but the space was too small for the silicon hose to pass!! That was Saturday job.
As the engine was out I took the plunge to take a few more steps backward??

Since I built up this engine and gearbox I have always had an oil weep from underneath on the selector bellcrank hinge post, when it was just a bush race engine used once every 5 to 6 weeks it did not worry me, if driven on the road I need to fix it, so Sunday job was engine out of subframe and the unit on the bench to split from the gearbox, now you lot get to see up its nether regions in all its glory, rods machined to equal length, (anything up to 4 thou variation) Lightened and balanced end for end then polished, all other go roundy and up and down bits were also polished and lightened, you can just see the distributor drive shaft.
No wonder it took me 9 months to build

Lightened flywheel + comp clutch, next weekend if all goes to plan i will remove the main and lay shaft from the gear box to get to the leaking O ring on the selector pivot post and anybody curious will get to see inside with its central oil pickup and selector shaft through the front of the casing

Sunday 7th June removed main and lay shaft from the GTM gearbox to allow access of the oil weeping selector fulcrum pivot in the base of the gear box, the pinion nut was tight and had big problems finding something to hold to gain enough leverage to loosen it, but after the 9.30 tea break sussed it out and got it loose, the modification to pass the selector shaft through the front of the casing actually looks quite simple, but when I did it, I had a lot of worries especially as if it all went ‘tits up” the chance to find a replacement gearbox here in Nigeria would be very close to zero.

The selector shaft is a direct copy of the standard selector on its left side, it is extended to be long enough to pass through a bronze sealed bushing in the front of the casing, the shaft had to have a cutaway where the revers gear passes over the top, this was made with no sharp edges to reduce the possibility of cracking in use, the revers selector had to be modified to give clearance as it would normally pass where the new shaft is, it all works and having done one it looks quite easy.

Interesting on the selector mod, I was always led to believe that you had to loose reverse for this mod, You have shown it can be done!

Hi Neil,
I did hear of twinny mini that had the revers deleted on the on the rear engine after I had done this and with a Twinny it would be OK. Done once it is quite simple, but looking at an empty gear case thinking shall I or shant I??? the machining was done late 1980's, the twiny did not get finished till almost 10 years later as I was collecting bits and had 3 engines and 2 body shells, only one complete and still being used as a bush racer,
Regards
John

LSD plate clutch mini diff, very nasty in a front drive Mini on a tarmac road, a whole new meaning to torque steer, OK off road.
Not sure how it will make a GTM behave, if too unfriendly I will have to get a Xpin diff to replace it.
In the mid 1980's when we fitted a Jack Knight Mini LSD in a Jedi, we only did one event before removing, since fitted Quaife and still using them.

Having cured the oil weep from the selector fulcrum in the base of the gearbox, put everything back into the GTM's nether regions, leaving my A frame crane and hoist where I last used it, it was not a nice surprise to find the A frame toppled over with the horizontal beam laying just in front of the car, we had a big storm mid week and when it rains here the temperature drops causing the wind to rush in, I never thought strong enough to blow over the A frame, but lesson learned, hook it up to something heavy to hold it down, if GTM's were just a tad longer, I could have had a chain block as a bonnet mascot, I did get a scrape across the passenger (R-H) door and spent Sunday clearing up the mess rather than doing something productive.
No step forward 2 steps back.

I’m interested in how you get on with an Lsd in there....?

I know someone else who tried it, and he said it turned the car into his worst nightmare to drive. :(

I think he did less than 10 miles in it before he removed it. :shock:

It is a plate diff so not as friendly as the viscous coupling or ramp types, so will just have to try and see, If I had a Xpin now would be the time to fit
