Other ( non boosted Renault ) R8 5 speed gearbox (again)

[cbx6_79]

Hi again!
Had a topic earlier about a 353-13 gearbox for my R8G. Have now replaced primary shaft bearing on that box. It is back in the car again, and seems to work good. While I fixed my 353-13 box, I had another 5 speeed in the car, but it seemed as that gearbox also needed some bearing attention. That box went out again last summer, and waited for my inspiration to come back , to be opened up. Got it open last week and replaced input shaft bearings for that one too. I then noticed it had a slightly different gearing ratio for 1. and 2. gear, compared to the stock 353 box.
Ratios are as follows: ________ Stock
1. - 43x14= 3,07 _____________ 3,61
2.. - 39x23= 2,25 _____________ 2,36
3. - 39x23= 1,69 _____________ 1,69
4. - 35x27= 1,29 _____________ 1,29
5. - 32x31= 1,03 _____________ 1,03
Are theese gear ratios familiar to some of you gearbox expert? Know back in the days you could get other gear sets, but this one may be put together from different sources of other Renault gearboxes. Just curious to know And it also have a 9x34 final drive, so it might be nice for road use

Odd one there. Std ratios are as you have listed, but you've got a Monte carlo 1st and later production second. They are all cut as one piece, so cannot be meddled with.
The teeth look kinda truncated, like they have been cut down, they haven't, they've been made like that. Something in my mind says Monte Carlo Normal ratios, there was also a court set. I'll need to have a look in the archives and get back to you. Better detail pics of the gear teeth would help.

Thanks Steve for your description. I have heard earlier about this spesific gearbox, that it had the "Monte Carlo" gearing, but I did not exactly know what that meant. When I had the gearbox in the car, the ratios seemed to suit the car very well, spesially with the 13 inch wheels that I have. 1. gear is a bit taller than stock, and the rest of the gears came in very tight. I felt the 9x34 also to be a better option for street use than the stock 8x33. Unfortunately I did not take many more pics before I closed up the gearbox.
