Well a rather annoying twist in the tale. Installed the crank the other day after completing all pre assembly prep. Everything seemed ok bar a slight bit of clearancing needed on the girdle plate. Took everything off and found a whopper of a scratch on one of my main bearings. Annoyed doesn’t come close!
I know the block and crank were crystal clean so I can only assume that my old pot of assembly lube had become contaminated with a bit of grit or who knows what. What are the odds?!?
So, yet again, a thorough clean of block and crank before sealing away on clean bags while I await new bearings to arrive….. and a NEW bottle of assembly lube by @torcousa via @nimbusmotorsport
