    Hi Paul.Selling??? You have sold your 17 to Max, so box for sale? I'm officially interested.
    I'm guessing the ratio types with num 34. More info from other AF members will be interesting

    Hi, Renault gearboxes had suffix numbers like that depending on the application. I don't know specifically what the -34 signifies, but my information says 365-33, -34, & -35 were all variants from the R17TS & R17 Gordini.
    They all have the same gear ratios:
    365-33, -34, -35
    1st gear 11/38 3.46:1
    2nd gear 17/38 2.24:1
    3rd gear 23/37 1.61:1
    4th gear 28/34 1.21:1
    5th gear 31/29 0.94:1
    Final drive 9/34 3.78:1
    Overall ratio in 5th 3.55

    365-02 to -07 had slightly taller 1st & 2nd, and were used in R17TS13/47
    3.61:118/42
    2.33:1

    365-00 had a taller 5th, and therefore taller overall ratio in top. It was used in the Lotus Europa Special and the R12 Homologation special.(no don't know anything about that, but that is what I copied from a source some time back)
    31/27 0.87:1
    3.29

    It might be a good idea to stamp the model ID onto the casing.

    Thanks everyone for the info. I was just a bit curious on the -34

    It will most likely be going up on ebay in a few weeks time for those interested in buying it.
    That'll let all the Renault, Alpine and Lotus people bid it up to help fund whatever I do next :-)

    I've got one. Comes with a free gearbox but you should see the price of the tag :-)

    Better get a LSD for the 365 box as well

    A snip at $1400, 365 box must be worth $3-4000 on the world-wide market

    Not a good idea to stress an already weak g'box. If anything I would upgrade the final drive/crownwheel pair.

    Problem with the 365 boxes was their diff center was too strong... with the 4 spider gears in the center the weak links were the crownwheel and pinion set, and the gearset.
    How do you upgrade the crownwheel and pinion?

    Nah, the four satellites are not the problem. The pinion/crownwheel are too weak.

    You get a pair machined from scratch by a reputable shop. If the price for a 365 g'box is indeed around the 4k $ mark, it is cheaper and better to just get a pair machined and make your own g'box by mixing and matching gears.

    Have to look into that... you’d get a primary shaft and secondary gears to suit made too?

    The only good part of the 365, IMHO, is the ratios. If I had a broken one I would try putting the gears into a 395, as they have a much stronger CW&P. Only thing is you loose out on diff ratio. But most want a working gearbox so why not just fit a 395 straight off ....??

    When we stripped the 365 to build the big 5 steed 330, and people found out we had a CW&P my phone rang for a year.

    The 395 has a run of the mill crownwheel/pinion no different to what you find in a 352. I doubt it is meant to deal with power of a tuned 807.

    Angru, the gears of the 365 is what everybody is after. I don't think they need modifying but I see your point. Strengthening the diff moves the weak spot elsewhere however I think it is easier to have these made to replace a broken one than the crownwheel/pinion. That said, they are just ordinary gears, inherently stronger than a hypoid, which is a compromise with a different purpose. Try a NG5 or an UN1 if you want a box impossible to kill.

    Yeah. That’s my point. If you can easily get a primary shaft and set of gears for the secondary shaft made to suitable ratios then the ng box would be a great candidate to build a close ratio box. If you talk about mixing and matching gears to get the ratios you want you need to have a primary shaft that will suit and as that’s a solid shaft with all gears fixed.

    Schlitie,
    The 365 can't even handle a mild 807, why do you think even sreeet driven cars have broken the CW&P, whereas the 395 has had the 2.0 and 2.2 Douvrin motor work through them and all still in good condition. Now find me a Proper R12/17 365 CW&P. there is only one place in Europe who make the after market sets and they are Prina in Italy, and they won't make you 5 or 10, they want an order of 50 min. and then you will wait a while, while they slot it into there current production Schedule. The R8 Gordini set is E1400.00 for a batch of 100. Contact GBS and see if they have in stock.

    Oh and "Driven" the 365 and 385 are not the same sets, one is a box in front and the other is a box behind the flywheel.

    My point is that the primary shaft is already available in a number of ratios, but you have to find it/the version you need/want. They used all sorts in various vehicles. Or jus get one of each you can lay hands on.

    The NG is a good g'box, but secondary shaft has a different kind of spline, you can't use pinions out of the '3' series g'boxes with it.

    Ray

    The 395 never pushed 120/160HP through a set of low gears. R18 had a mere 60HP or some such and the ratios are taller than the 365 so it doesn't build the mechanical advantage to multiply the torque to the same level. But if you're in the market I have a matched 395 set (c'wheel/pinion) brand new in the box right here.

    You don't need to go that far. If you have a cool $10k burning a hole in your pocket, Albinsgear in Vic will make you a one off right now (can make a custom ratio too). That's what they quoted me. For a 10 set run, they reckon you can have each set for under 2k AUD and they said it would be much stronger than the original. Have a look on their site, they do some serious hypoid stuff, most of it exported too, including for Dakar racers.

    GBS don't have the final drive and/or the crownwheel.
