western Posted August 15, 2006 Share Posted August 15, 2006 (edited) This might help ----- Bell housings Gearbox serial number need for this [the 1st 3 digits at least] LT77 --- all upto chassis number LA939975 50A -- FRC9865 ------- now corrected 56A as above 60A -- FRC6154 61A as above V8/R380 FTC3922 300Tdi/R380 FTC3921 200Tdi/R380 use FTC4018 a 'stumpy' 11cm overall length bellhousing, apparently not the 14cm LT77 variant that I originally thought. all the above are for Defender these for Discovery upto chassis number LA081991 V8/LT77S---------------- FRC6154 200Tdi/LT77S ----------- FTC1270 300Tdi/R380 ------------ FTC3921 V8 carb./R380 ---------- FTC3922 --- superseded by UNB100190 V8 efi/R380 ------------- FTC3922 --- as above. these for Range Rover from chassis number starting CA to HA610293 VM diesl/LT77 ----- FRC8570 V8/LT77 ------------ FTC6154 these for Range Rover from chassis number JA610294 200Tdi/LT77 -------- FTC1270 V8/LT77 ------------- FTC6154 VM diesel/LT77 ----- FTC8570 300Tdi/R380 -------- FTC3921 V8/R380 ------------ FTC3922 ---- note supersession as per Discovery list above.

HoSS Posted August 15, 2006 Author Share Posted August 15, 2006 Is that a typo' or correct? - " FRC9685 & FRC9865 " Quote Link to comment Share on other sites More sharing options...

HoSS Posted August 15, 2006 Author Share Posted August 15, 2006 So... If the R380 & LT77 both use the FRC9865 then that end must be the same. Therefore i should be able to bolt a R380 direct to my current LT77 bellhousing....no? Quote Link to comment Share on other sites More sharing options...
western Posted August 15, 2006 Share Posted August 15, 2006 (edited) Well my R380 bolted straight to mine [200Tdi with FTC4018 ] OK & a LR main dealer did the orignal R380 fit, they didn't have any problem,IIRC the R380 to V8 has a different mainshaft, where's Dave Ashcroft when you need him Edited July 6, 2011 by western Quote Link to comment Share on other sites More sharing options...

Mr Ashcoft told be i'd need a new bellhousing, i was just seeking a second opinoin as it seemed strange as i thought the r380 was the same fitting pattern as the LT77 I'm not actually any wiser at the mo. Anyone know for certain? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 16, 2006 Share Posted August 16, 2006 YES I have experienced this... The R380 is slightly longer (~25mm) than the LT77, so with the V8 for reasons unknown they made the bellhousing ~25mm shorter. You can physically bolt one to the other, but the input shaft will end up 25mm too long or too short and that's a major PITFA. I ended up buying a bellhousing from Mr Ashcroft as it was just easier and quicker than trying to find a correct one elsewhere - seems most of the LR "experts" don't realise the difference either and several tried to sell me LT77 versions Oh and in case this should end up in the tech archive - the tail housings that contain the gearshift are completely different internally between Defender and Disco/RR so you can't swap the shift mechanism over - ask me (and Marco Cosic) how we know Oh, just found a nice piccy of my R380 - this is the correct bellhousing and a Defender shift mechanism (comes forward from the tail housing): This is the RR/Disco shifter tail housing (viewed from above looking in): This is the Defender tail housing (viewed from above looking in): Quote Link to comment Share on other sites More sharing options...
HoSS Posted August 16, 2006 Author Share Posted August 16, 2006 Thanks FF. I knew i should believe Ashcrofts, I just don't like taking anything for granted without first knowing why! Quote Link to comment Share on other sites More sharing options...

nickm Posted October 6, 2006 Share Posted October 6, 2006 anyone know if a rangerover 3.5 v8 4speed auto box would bolt onto a disco 200tdi engine if it doesnt can i just swap the bellhousings over and would the output shaft be the same length and diameter cheers Quote Link to comment Share on other sites More sharing options...
western Posted October 7, 2006 Share Posted October 7, 2006 EPC tells me the RRC 4 speed auto torque convertor housing is RTC6594 on V8 vehicles which is the same on Discovery 1 4 speed auto & V8 vehicles, but the housing on a 200Tdi Discovery 1 auto is STC1581, the parts drawing doesn't give enough picture detail to determine the differences, probably have to have one of each housing side by side to tell, hope that helps.

callum Posted October 7, 2006 Share Posted October 7, 2006 i'm slightly confused still clarified on a v8 the parts are not interchangeable. but for 4 pot... FRC9865 fits on end of lt77 and also fits on the end of r380. does this overcome the 25mm length problem in this application regarding the input shaft? also, regarding this stumpy bellhousing, surely the input shaft would be way too long, given the difference in bellhousing length between r380 and 4 pot lt77, were you to attach frc9865 to an r380. am i getting horribly mixed up?

Some R380 have a short mainshaft for different applications, like my own R380 which has the 'stumpy' bell housing & bolted to my Defender spec 200Tdi. the 300Tdi engines sit further forward in the engine bay & have a longer mainshaft & longer bell housing.

western Posted October 7, 2006 Share Posted October 7, 2006 not sure how rare the short shaft boxes are, but I'm sure Dave Ashcroft would know. Quote Link to comment Share on other sites More sharing options...
Luwts Posted June 4, 2008 Share Posted June 4, 2008 anyone knows if an sd1 V8 lt77 can be adapted to fit in landrover 90? would the engine foul the bulkhead or no? Luwts Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted June 4, 2008 Share Posted June 4, 2008 anyone knows if an sd1 V8 lt77 can be adapted to fit in landrover 90? would the engine foul the bulkhead or no?Luwts I asked this question a couple of years ago - apparently you cannot mate the box to the LT230 in any way.

Guest noggy Posted June 5, 2008 Share Posted June 5, 2008 right, so will a 1988 3.5v8 with a 3 speed auto, connect to a (defender)LT230 instead of the borg viscous coupling? Quote Link to comment Share on other sites More sharing options...
DaveSIIA Posted June 6, 2008 Share Posted June 6, 2008 right, so will a 1988 3.5v8 with a 3 speed auto, connect to a (defender)LT230 instead of the borg viscous coupling? Yes. BTW: You will need a different front propshaft. Quote Link to comment Share on other sites More sharing options...
Guest noggy Posted June 6, 2008 Share Posted June 6, 2008 sorted thankyou. so the stud pattern from a defender lt230 is the same as a disco lt230? Quote Link to comment Share on other sites More sharing options...

western Posted April 28, 2009 Share Posted April 28, 2009 original list amended change done in italics seems my thoughts on a short shaft R380 to my 200Tdi were incorrect, the bell housing part number has been amended. Quote Link to comment Share on other sites More sharing options...
