Dear All, I am a newcomer to Listers but have always rather fancied an old diesel. So rashly or otherwise I bought a seized LR2 nearby. It’s already starting to suck money out of me, but the voyage of discovery has brightened up my days no end. I have a few engines at home, landrover 4 and 6 cyls, Jaguar 6s and Rolls Royce B60s and a B80, but no twins diesels!
The engine is nearly stripped. It was seized both in the barrels, and the ali flywheel housing had corroded so much that its was also stopping the crank from spinning. I’ve stripped to the point where the only thing left to remove is the crank. So two questions at this stage:
1. To remove the crank (to completely clean the case) I can see that the centre main bearing housing must move actually with the crank, but what then? Does one split it between its current position and the end bearing housing or does it have to pass through the latter before being split  and removed? What sort of fit should it be - it seems tight, but I don’t want to bend the crank at the big ends in levering it forward.

2. I’ve seen some relatively cheap + 20thou pistons. Should I get the barrels bored to suit?
Looking forward to chatting to you all as appropriate and thanks in anticipation.
Regards
Andrew
