I recently bought an 89 744 with a bad crankshaft. I knew there was trouble, and paid accordingly, but as an example of how tough Volvo engines are, I have run an independent Volvo service shop for 16 years, and worked in dealerships for 6 years before that, and I did not know that the mid 88 and newer crank has bigger main journals. Never had one apart until they were 14 years old. And this one has 5 pristine mains, three pristine rods and one completly roasted rod bearing. And then my machine shop didn't check bearing availability until they turned the rods .030, and .030 bearings are not available, so I can't even spray weld the journal, which I don't like to do anyway. So, I have a couple of 55mm cranks, but cannot find a 63mm from any of my regular suppliers. New is $700cdn+. I bought a 155,000km used engine and installed it but now have a perfectly good 325,000km engine to freshen up. And, since I bought a set of pistons and gaskets to use in it, a used crank would be a nice find. Or a source for .030 mains which Volvo does not make, which probably means .020 is the limit. Or maybe a sale for the head to cut my losses. So after all that, does anybody out there have a 63mm crank or know a wrecker who does?
