Identifying Transfer Boxes

(1/2) > >>

graham2306:
I have got a transfer box laying on my garage floor that I thought was out of a Discovery.  Mate of mine had a look at it today and said the gear lever linkage is definitely different to his Discovery box and the handbrake mechanism looks identical to my Defender one.  So short of opening it up and counting the teeth on the cogs anyone know how to identify what it is?  Don't want to put it in and find its the same as the one I took out.

Cheers

Graham

This is gona sound crude but it works. Get a input shaft to go in the box which would be where the gear box goes in. You either use a rear shaft of a 5 speed or a front shaft from a series box. Put the transfer box in diff lock,mark the temperary input shaft against the casin and mark the outputs on the casin.Repeat it on both transfer boxes doing a 360 on the input. The output thats turned the least is a higher ratio. ROCKET SCIENCE!!!!!!!!!!!!!!!!!!!!!!

dose it not have the ratio stamped on it?  normally by the cover for the pto out put, i think. disco is 1.44 defender is 1.2

I'll have a look, thanks

The ratios are on a sticker at the back of the casin. A defender is 1.411 ,200 disco is 1.222 and the late 300 are 1.211 which is the highest one.
