This is what was left of the big end bearing and damage it had caused to crank pin. The photo of the crank pin shows where the locating dowel goes and how the end of the crank pin is split, another dowel goes in the end to open the split and lock the whole lot to the crank web. This proved to be a bit of a challenge to remove as only a small diameter drift could be used which had a tendency to bend.
Due to workload and my saying the job was not urgent it took a while before I was able to collect the engine but it was well worth the wait. A crack in the water jacket also had to be repaired, luckily it was only the outer and had not damaged the bore. Photos of the parts at Cox & Turner awaiting reassembly.
