--- Quote from: "V8MoneyPit" ---Is the SD1 auto different to the Range Rover auto then?

Mine was from an 87 ish Rangy auto and there was no spigot bush at all in it. The manual bronze bush just pressed in to the crank.

Yes they used a different gearbox which had the same size spigot as a series manual box. Hence the problem, folk would drop an SD1 V8 in to a series three and not bother to change the spigot bush as it was the same size. Trouble is Rover fitted a steel bush. As there is no rotation between the crankshaft and the spigot of a torque converter it was fine. With a manual box everytime you put your foot on the clutch there is rotational differences between the spigot on the mainshaft and the crankshaft. If you are lucky it seizes and breaks the spigot off. Now that may sound bad enough, but at least you can still separate  the engine from the gearbox. Some however don't break but the heat welds the two together. Now try separating the engine and gearbox!!!!!

It is very easy to remove the spigot bush bye the way. Just fill it with grease, find a piece of rod (old bolt) the same size as the spigot, thack it into the grease, hydraulic action forces the bush out. Or you get covered in grease if you used too small a bolt :-)

Well, you learn something new every day here :lol:

I'm assuming the lack of bush in mine is because the torque converter supported the shaft so it doesn't need one.

Edit: Cancel that!!! Just figured it out. The spigot on the front of the shaft must be larger on the RR gearbox.
