Un1-13 flipping crown wheel

[barry howard]

Hi - Sorry if this has been covered before, i have tried to search this topic but no answers have come back.

I have a UN1-013 which has had the Derek Bell upgrade, im looking for advice on how to flip the crown wheel over to the other side so i can use it for rear engine.

I have split the box but the when i lay the crown wheel on the other side it doesnt marry up with the pinion as the teeth are set at 45 degs :huh:

Many thanks in advance

Mid engine or rear engine?

I cant comment on the renault trans but not all of the transaxles can flip diffs. Renault do a reversed model of the un1 in the Alpine gta . It might pay to look one of those out. (page four) http://www.rs200replica.co.uk/assets/applets/UN1.pdf

The pinion shafts and crownwheels must be available because renault make a version the way you want it.

Appreciate the info

There is away to do it i read about it while ago but can find that doc, so thought id speak to the GT40 lads as thought the un1 was rear engine mounted in these and i was in hope there would be man who knew how i can

They are run as is on the gt40 so no one here needs to flip a diff. this may be of some help.

aaahhh that may explain a lot, surley the un1 is in back wards so youd you have 5 fast reverse and one slow forward im curious how have you got them mounted is mid engine then ?

Barry, when the UN1 is in a front wheel drive car is sits behind the engine, with the bell housing towards the front of the car, as it does in the GT40s. So the orientation of the gearbox wrt the engine remains the same, engine forward, gearbox behind.
