Has anybody converted their transfer gearing to 3.9? is it an easy job or a specialist job? Cheers.

It`s easy, you don`t have to take the gearbox out of car either. Take of propshaft, and open the rear part of transfer box, then you will see ho it`s mounted

Dave Hewy

iTrader: (3)

I did and he said he would have a look at what he has. Not checked the socket but i have the workshop manual on my computer so ill check and let you know. Might need pulley drawers to pull the spider off too.

I might be being daft, but why do you need to touch the output shaft to change the drop gears?

otherwise you cant remove the casing

kjc300

iTrader: (1)

I think you can - I did it the other day!!!

THE RADMAN

iTrader: (2)

yes you can,im getting confused,i removed mine to do the oil seal but it doesnt need to come off for the casing to be removed lol

kjc300

iTrader: (1)

I nearly went out to try it again lol (spare box in the shed!!)

what are the benifits of 3.9 gearing?

Have you got the shorter chain and smaller wheel then Dave?

when Steve Scott did mine on the first gearbox many years back, he had to grind down a small section inside the casing to enable it all to comfortably fit.

current box, being Barra - he just kept my 3.9 step off's and casing when assembling the new internals into the box.

dont forget, you need to change the rear diff at the same time or you will be driving the front to rear wheels at different ratio's.

kjc300

iTrader: (1)

NO you dont, just undo the bolts around the casing and one near the middle - you dont need to touch the output shaft at all.

Yes Kelv, Pete Doughty did the 3.9 conversion with new chain and smaller gear (its paul ripleys old box) i was thinking of going back to standard ratios when i put it in the car but now i've changed my mind and am going to source a 3.9 7" rear diff instead.
