Ashcroft Transmissions sent me the following when I asked them about replacing my 200TDI Gearbox and Transfer box ( I have an LT77 and a military 1.667 ration Transfer box)

"you have a few options with the mainbox and the transfer case,
mainbox :

you can either stick with the LT 77 which we are able to supply at £ 550,
rebuilt, outright or we have in stock the short bellhousing R 380 made to
replace the LT77 at £ 825, new crated, outright, these are the latest suffix
L type, you also have option of fitting an oil cooler to the R 380 which
would be beneficial in hot environments,

transfer case :

if you have the 1.667 now I think it would be safer to fit the 1.410 which
is 15% higher in high range, the disco 1.222 ratio will be 30% higher and
this may be a little too much in a loaded 110,"

Does anybody have an knowledge or advice regarding the short bellhousing R380?
Assuming it's better than a LT77?

The R380 is a much better box to drive with than the LT77 (easy way to tell them apart, oif you don't know, is that on the R380 reverse is "behind" 5th, ie to the right and back, whereas on the LT77 it's left and forward, next to 1st gear)

The "short bellhousing" bit just relates to the fact that the R380 is longer than the LT77, so needs a shorter bellhousing to keep the gearbox in the same place as the LT77 was, therefore enabling you to keep the same propshafts and floor panels.

in a production 300Tdi (where the R380 was used) the engine is mounted quite far forward, so the gearbox is more or less in the same position as the LT77 was (although not quite, as the props are different length) and a different transmission tunnel is used.

the oil cooler is a handy thing to have, although i'd use a military cooler as opposed to the civvy "euro" cooler. the military one is a proper little radiator, like the old series military FFR's used on the engines, whereras the euro cooler is just a loop of pipe mounted under the radiator.

I'd go for the 1.4 transfer box too. your 200Tdi will pull that gearing easily (especially as it would then be as the factory 200Tdi's were... 1.4:1 transfer box was standard) it'll make your truck much quieter as well as the engine won't be screaming its nuts off to keep road speeds up. you could always tweek the pump a little to get some more power out of it as well.

did you get my email the other week Darrin? re: the GPS lead.

cheers

jamie

Cheers for that - is it worth the extra money then?

Ashcroft say they can't supply the oil cooler. Is it a standard landy part?

(sorry - will reply off line about the lead - DeiselJim posted me a gps lead to Spain when mine went caput so two thumbs up to him and the friendly ways of the hubb!!! ;-)

I'd say its worth the extra money, just for the ease of driving, and as they still make the R380 but not the LT77, in years to come it'll only be harder to get parts for the LT.

Yeah, the oil cooler parts are standard LR bits, i've got a parts list somewhere on my PC, i'll dig them out.

No worries, I'll get Dunsfold onto it when ready to rock.

Does anybody else have any comments?

Here ya go:


this is the adaptor bit (# 18) that you need on the side of the gearbox, it replaces a little external pipe bypass thing.




the Td5 "euro" coiled pipe




the V8/military "proper" cooler and bracket




part numbers





Here is another R380 cooler, listed as the non v8 ones (so i assume 4 cylinder diesel civilian Tdi's), slightly different shape, like the ZF auto cooler really.





part #'s


If you needed the full wolf parts list, any LR dealer should have them, they're not "secret" so no reason for not giving you them, but i think most of the bits are listed above.

Jims right on the ball - go for the R380 - much better box than the LT77 - good to see you get the latest suffix L - the gearbox oil cooler isnt essential - but if your working the vehicle hard then worth considering.

with the gearing - go with the 1.410 as ashcroft and Jim mention - its a nice mod - the vehicle will cruise better and you might get a fuel consumption improvement too (depending on which way the winds blowing!)

later
