Thread: Series Gearbox

Thanks for all the replies.
Guess its a bit like my Fergy at home and the 100HP JD a work.
Or my LH brake on my Greeves or RH on my Honda.
you have to drive to suit whats fitted.
Also my youth as a Linesman in Cornwall, Mid 70's driving S3 LWB Land Rovers, being told by older co workers, to
'Double D Clutch, all the time, when I was driving. S3 had syncro.

But not too early, so you get the later bigger diameter intermediate shaft.

Do you have info on when these bigger diameter intermediate shafts were introduced in the transfer boxes with 2.88:1 low range? from build time or gearbox serial number? I now have an Australian assembled 1961 LWB, Last registered maybe 20 years ago, still has 1961 issue Victorian plates on it and an old rego sticker indicates 13th June expiry.

However, I have an LT230 transfer box with 1.222 high lying around. its 3.32 in low should be better than the older Series low range. I reckon constant 4WD should put less stress on drive components with my type of usage than having driveline "wind up" when on hard ground and would get rid of need to regularly engage and disengage free wheeling hubs. Am interested in trying it behind a Series 2 or 2A gearbox if not too many problems making them fit. Has anyone ever done this?
