Just bought a job lot of rebuilt gearboxes , rebuilt motor and a ute load of new and rebuilt parts , the gearbox on the rebuilt 1100 is a 22G1128 and has hardie spicer joints . I'm a bit rusty on IDing remote change boxes but to my way of thinking it's a basic remote change 4 synchro box ? ALso has a temp sender (I think it is anyway) on the front of the gearbox housing .

yeah, 4 speed syncro with "REVERSE LIGHT" switch --->(Not Temp sender)

could be a MK2 "S" box tho, check the leygear number???

You should put your heart & soul into everything you do.

Ahh OK , thank's Matt , I'll be stripping it down again before using it (I don't care if it's supposed to be rebuilt , I'm checking to be sure) and will check then , just seemed a bit odd for someone to have put hardy spicers on it but then again it's not difficult if you have them or the diff sitting about to use them .

I thought it was really odd to have a oil temp sender on the gearbox but couldn't think what else it could be , see what happens when you only play with rod change or 850 boxes .....

Could also be an 1100s gearbox as well.
My wife's has that on her 1100s with original loom wires leading to it.

By what I've been told, that serial number simply means it is a 4 synchro box, not necessarily a Cooper S box. It is inside that counts. You will need to identify the gears.

If cluster gear is stamped 22G1040, it's a Mk2 S.
Having Hardy Spicer joints indicates it might be one, but the gears are the clincher.

Ok , thank's guy's , I'll be sealing this motor up for a few months till I need it so will get back to you then about the numbers on the gears . I've got my fingers crossed though .

Stripped , checked and rebuilt the cheap motor with the unknown gearbox today , 20 though over 1100 never been started since the rebuild , std bearings , spotless crank .....

WOOHOO ....


The twins came with the motor , air cleaner I had sitting around and extractors are from my van .



Not sure but I remember someone saying factory cooper s cam's had two rings cast onto the blanks , anyone know if that's right or not ?

That part number rings a bell with me. GT maybe? Agreed on the "insode that counts" bit.

I believe you are right re: cam with rings on it.

GT box exactly same as Mk2 S box, with 22G1040 cluster gear in.

re the cam,
3/8 lobes with 2 rings (spider drive) is a Mini or Morris 1100 automatic.
3/8 lobes with 2 rings (pin drive) is 1100 Sprite Mk2.

1/2 lobes- Early S with 5/45-51/21 timing had no markings
1/2 lobes- Later S with 10/50-51/21 timing had 1 ring.

My source- Vizard, p262.

And here's me thinking you just rattled them off your head - must be getting old eh Kev if you have to doublecheck your answers!

No he's know the page number off the top of his head also

That would be it then , any ideas if it's slightly better than the equivalent 1100 mini cam or similar ?

I'm definitely liking this job lot of bits .
