Back on page 217 of this thread I showed what I'd done to a crank and rod on one of mine after an oil line fractured. As Worty said 'BUGGA' Well, got the crank reground at T&L Engineering and got it home Friday morning. One grind on all three journals. (No question of 'just' doing the affected one - there was some scuffing on the others and there's no way one should just do one big end even if the other was perfect I was very firmly told (ref Q earlier in thread).
Wasn't as straightforward as I'd hoped though. The left hand Thunder rod had taken a hammering - woe - and was 4 thou out of round. So had to be rectified, which meant the other one had to be made to match. It turned out that that had also taken a hit, but much less of one - so 'well worth it' and supports my long-standing belief that rods need checking all ways to Sunday in the event of a serious bottom-end issue. The centre main bearing has thrust washers as per typical car design to locate the crank - and they had picked up bearing material that was embedded and had to be replaced. The oil ways in the crank were blocked with solidified molten muck. A minor weld to a lug that takes a stud to hold the chaincases was also seen to - result of a breaking rear chain some years back.
Not a freebie by a long chalk, but worth every single cent.
Interesting to learn that the difference in weight between the new shells and the old was up near 20 gr - but not sure what weight of steel was removed in the grind to compensate. But the side-to-side balance is the same or near enough, so didn't spend an extra wedge on having the thing balanced dynamically again. In any event, the pistons etc will be replaced at some point as they're on 25K miles, or about 'half-way' probably, so balancing again with what's there wouldn't have made sense even if I'd supplied the pistons, rings, pins and circlips over.
A long day in the shed yesterday got me to 'nearly back together' and hope to be running again in a day or two.
