Hi all - i posted last week about nasty transmission noises when coming to a stanstill - well!!! Didnt use her all week and on a short trip on saturday the noise soon retuned with a vengeance - i dipped the clutch and braked and we juddered to a halt. After a bit of jiggling with the high low selector i managed a few jerky feet forward accompanied by the sounds of shredding metal!! Her indoors was summoned with the toolkit - jacking up a front wheel and turning it slowly repeated the horrendous noises from the transfer box area, raising and spinning a back wheel seemed ok. To get home i removed the fron prop and was towed home very slowly.
It sounds like i have shredded the centre diff/transfer box. My questions are
Can the transfer box be removed with the gearbox in situ? - my haynes is a bit vague in this area.
This is an early 90 - what transfer boxes will fit directly and what sort of price should i expect to pay?
Would it be easier to fir a gearbox/transfer box complete? - again what ones will fit? - disco etc
thanks steve

Hi steve,

you need an LT77 1:4 ratio for your 90... Where abouts are you?? The transfer box can be taken off the back of the gearbox with it all in situ. (I've done it ;) )
second hand for a decentish one, expect to pay about 100 - 150 on fleabay.. :) giz a shoult if you need any advice on how to do it..

cheers
Dave
 
thanks Dave - im in Newark notts. there is an ex auto transfer box on ebay but 1.22 ratio - would this fit and do you think it would make gearing too high - i think im currently udergeared as running on 15" wheels
thanks steve
 
Sounds similar to my transfer box woes. 1.22 sounds a bit high for a Defender, depends what you use it for.

Be prepared, if it's ground to a halt like that & may have been on the way out for a while the splines on the gearbox output shaft may be damaged too.
 
I run a rangey 1:2 ratio in my 110 CSW but that's a200tdi. I dont know what your motor is but dont pit a 1:2 in anything less than a 200tdi.

As Markus said if the bearings have broken up in the transferbox, you'll probably have some mainshaft wear from the gearbox. I had a bit on mine but the input gear of the replacement transferbox was really good and almost new so it took most of the slop out of the mainshaft :)

I've got a 1:4 box but it's probably no better than the one you've already got :(
 
the upgrade to a 2ootdi was already planned before the box let loose as the existng 2.5 n/a is like me - on its last legs! so the 1.22 works ok with the tdi? steve
 
Looking at the Ashcroft site the low range of a stock 1.222 transfer box (basically a stock disco tdi one) is the same as the low range on a stock 1.410 (a stock defender one) - i.e. 3.321:1 - so it shouldn't affect low range use at all.

Provided you've got the grunt to turn the thing (Tdi would be fine, TD should be ok) it would make a Defender a much better road prospect than standard and allow for a nicer cruising speed on the motorway.

Cheers,
 
yeah it works fine on a 200tdi..It'd be even better in a 200tdi 90 (mines a 110 so a bit more weoght to shift around. My transfer case came off an 86 rangerover.. it take a wee bit getting up to 70 but once you're there it fine. even some left for overtaking :)
