kkk2 Posted August 10, 2008 Share Posted August 10, 2008 I have a lt77 and 1.2 xfer box fitted behind a 6 cylinder 4.2 MWM tdi. 422ft/lb @1500prm 204hp@3500rpm also running straight through 3" exhaust. It came from M&D Engineering(Anglia). It drives brilliantly and has good fuel economy, however on medium to long runs the gearbox is getting really hot, much hotter than the same type box in a 200tdi. I know it is possible to add a cooler to the R380 but is there any way to cool the lt77?. As the engine is 6 cyl. there is no room to move it forward enough to fit a R380 behind it without major alterations. Any help/suggestions?

I'm 99% sure the same kit for the R380 fits into the LT77 as well. it's just that adaptor thing that bolts onto the LH side of the casing.

I also run an oil cooler on my R380 not that it seems to make any difference to the heat in the seatbox area. mike Quote Link to comment Share on other sites More sharing options...
Bush65 Posted August 10, 2008 Share Posted August 10, 2008 I have a thermatic housing (for oil cooler) from an LT77 on an R380. I believe there may be a difference in the threads of the ports, but that should not worry you. Quote Link to comment Share on other sites More sharing options...

I believe there may be a difference in the threads of the ports, but that should not worry you. Have you any photographs of the housing please? thanks, I have looked at a spare lt77 on the groung and on the lhs there are only the filler plug and a large plug at the bottom of the box, I understood the oil was pumped from the gearbox pump through the cooler?

Guest diesel_jim Posted August 10, 2008 Share Posted August 10, 2008 Righto, run all done! Here's the "oil cooler adaptor":, there are different part numbers for different boxes. i thought they were the same, maybe Ashcrofts can shed some light on it, but microcat shows: FTC2104 for V8 R380 FTC2687 for BMW 2.8i R380 FTC1404 for LT77 There is also an "oil temparatue warning light" adaptor, which just turns on a light (you whould have though thet'd combine it int the oil cooler one as well FTC2104 for LT77 ( mine looks like it'll fit the R380 as well) ...pictures on next page: Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted August 10, 2008 Share Posted August 10, 2008 FTC2104 for LT77 ( mine looks like it'll fit the R380 as well) And the cooler adaptor fitted to the gearbox: Quote Link to comment Share on other sites More sharing options...
kkk2 Posted August 10, 2008 Author Share Posted August 10, 2008 Diesel Jim thanks for the photos, beside main dealer who would have the bits ? how big a cooler does the system have and where does it mount? thanks again Right went out and had a look, there is no place to mount this part on my Lt77, anyone know at what suffix this option was available on lt77's?

Guest diesel_jim Posted August 10, 2008 Share Posted August 10, 2008 Diesel Jim thanks for the photos, beside main dealer who would have the bits ? how big a cooler does the system have and where does it mount? thanks again There's several different types of radiator available, some look like the "bog brush" long and thin, some are a square type (the military wolf's used these) very similar to the engine oil cooler. the factory "euro" spec Td5 box cooler is nothing more that a bent piece of 1/2" pipe! it goes from the gearbox up to the front cossmember, loops along it and comes back. Fot the cooler adaptors, try giving Dave @ Ashcrofts a shout, he sourced my last one for me, he may have more in stock (second hand but perfectly good) Quote Link to comment Share on other sites More sharing options...
mmgemini Posted August 10, 2008 Share Posted August 10, 2008 My gearbox oil cooler, That should really read oil radiator is a normal type. It's mounted behind the front grill below the grill opening. I cit the front away like the first TD5's were at the bottom. It's also mounted on the front panel at the bottom. The biggest problem I had was finding the hose adaptors from the Land Rover Wolf pipes to the flexi pipes to the oil radiator. I used the Wolf steel pipes but I wouldn't pay the price for the Wolf flexi hoses. I might have the part No's of the pipes and clips somewhere. mike Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted August 10, 2008 Share Posted August 10, 2008 .I might have the part No's of the pipes and clips somewhere. mike Here ya go: re: the wolf pipes. DLR (Dunsfold) have a load at the mo, they keep advertising them on ebay. £15 each. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted August 10, 2008 Share Posted August 10, 2008 None of those pipes are anything like I've got fitted Jim ?? Although mine are Wolf ones for the 380. How does LESR2749 sound Jim ? I didn't go for the Wolf oil radiator because of the size of the thing. mike Quote Link to comment Share on other sites More sharing options...

mmgemini Posted August 11, 2008 Share Posted August 11, 2008 I've still got a double row bog brush here Jim. There's plenty room at the bottom of the front panel if you do what I did. The holed steel not only covers the bit I cut out but makes the cooler mount as well. mike Quote Link to comment Share on other sites More sharing options...
