Discovery bellhousing to 2wd LT77 gearbox?

[flutey00]

The title says it all really. Perhaps rashly, I've bought a V8 discovery LT77 bellhousing off ebay to mate to a RWD LT77 gearbox. I did this because it was thirty quid as opposed to the hundred plus for a RWD bellhousing. My logic being the Disco has a V8 at one end and an LT77 at the other so it should be OK. Any comments?

Thanks Vinny

Hi Vinny, welcome to the forum,
sorry to be the bearer of bad news, but there is a reason for the differance in price of the two bell housings, the discovery one is deeper (front to back) and if you put it on a 2wd box the input shaft won't reach the engine/clutch, also if you swap the input shaft for a disco one you then bave the gearleaver much further back in the car.

As a matter of interest, why is this? I noticed when looking at fitting a ZF 4HP22 auto to a RWD from a Range Rover that the bell housing was much deeper than needed - the torque converter is spaced off the drive plate to match. I assumed this was to match the length of the manual box between engine and transfer box - but didn't realise the same applied to the manual.

hi
the bell housing is longer in the discovery and rangerover the engine has to be far enough in front of the bulkhead to enable you to get the plugs out while at the same time the back of the gearbox has to mate with the transfer box that has to be as near the middle of the car as possable, if you want to do this without using a short prop shaft between the easiest way is to space the gear box from the engine. In the 101FC the reverse is the case, again the transfer box position is pretty much fixed but in this case they wanted the engine as far back as possable so the driver had some foot room, so in this case they used a very short bell bousing (and only fitted the 4 speed box which is much shorter, net result the 101 engine is about 10 inches further back than in a disco.

Interesting - thanks. Presumably the 101FC was never available with the ZF 4HP22 auto? The Sherpa RWD with the V8 and ZF auto seems to use the Range Rover long bell housing.
I ask because I was considering fitting a 4HP22 to my SD1 - but the long bell housing fouls the bulkhead.

Hi Dave
No the 101 FC only ever had the 4 speed manual, there never was felt the need to give the army a luxury version of this vehicle . trim level is a bit basic aswell .

I wouldn't call 101 trim basic. Non existant is more accurate!
