ive just stripped an engine ive had sat at the back of the shed, gearbox seems to be pacemaker?

loose tree
1st 50 11
2nd 40 13
3rd 39 17
4th 35 19

what should the gears measure so i can tell if i have a weak one or not?
many thanks,

Is the main shaft drilled, or solid likethe GP...??

its drilled

Very likely an early one which used the LI type clutch bell with the center shaft....nearly all the later ones had the GP type clutch bell fitted with an LI button on top, so were not drilled...I cant find the webster manual, or I would give you the measurements of the gears cus they are in there...

in the back of Stickys iirc
I'll have a look if you haven't got a copy

later type not bored 3rd gear across 5 teeth 33mm early and 33.8 on later

thanks 4 your help jim's , byron i have stickys book il go have a look,
thanks

just measured 3rd, this throwsa spanner in the works 33.8, but tree is bored.

what does this mean, and which is the weak link , the tree or gear?

The very early Late LI special's gear boxes used the earlier type clutch... this was later changed to the center less bell as or similar to GP...So you have a very early Late type LI 150 special... ...

Or you've bought a very cheap vernier gauge and its fooled you.... ..

well lets hope it's not the latter, i shall double check with another set but they werent cheapest verniers!
so this box is good for a high powered motor then?
