moore101 Posted April 7, 2010 Share Posted April 7, 2010 if all goes well with MOT friday and trial at weekend my lightweight will be getting a new engine and gearbox next week. its getting treated to a nice running 3.5v8 on efi and an lt77 and 230 box out of a defender (so short bellhousing) now ive got the clutch pressure plate off the diesel out of a rangerover and it seems like the fixing holes may have the same spacing as my series pressure plate? would i be correct in thinking the diesel pressure plate will have stronger springing? if not (or if the mounting holes are spaced differently) would my 2a pressure plate work with a series 3 style release mechanism that the lt77 has. is there a heavy duty version of a diesel clutch (9.5"?) as a v8 size clutch wont fit in my adaptor plate. (and before anyone says; the reason im using the adaptor plate and short bellhousing is because i dont want to modify bits to move my engine forwards, and i dont want to end up with a really short rear prop or gearlevers in the wrong place) also im slightly confused on spigot bush size. i have a measurement of 24.85mm for the inside of a v8 crank which is as near as 31/32" does this sound right? and i have a measurement of 22.22mm for the diameter of the lt77 short bellhousing input shaft of 22.22mm which is near enough 7/8". do these diameters sound about right? and if so is there a spigot bush that size? how big is a v8 input shaft on an lt95? cheers, alex Quote Link to comment Share on other sites More sharing options...
Aragorn Posted April 7, 2010 Share Posted April 7, 2010 normal V8 spigot bushes are 3/4" internal diameter. There isnt an off the shelf bush, you'll need to have a V8 one machined out to 7/8", and the wall thickness of the bush ends up very thin making it tricky to fit.

moore101 Posted April 8, 2010 Author Share Posted April 8, 2010 right then, will a 130 clutch cover fit? (is it more heavy duty?) part number URB100760 from paddocks does it have the same fixing hole spacing as series? and then can i use a FTC1994 plate with the short bellhousing gearbox i have? spigot bush im probably going to get an adaptor made up to hold a diesel spigot bush in front of the crankshaft which will end up shorter than standard, but the input shaft on the lt77 i have doesnt seem to want to wander away from centre as much as the input shaft of the series box i have anyway. trying to make a list of parts to order so that i can do the swap in as little time as possible.
