Adamant's engine doing 220rpm after fitting new little end bearings. It is significantly quieter than in Adventures of Adamant 4 where it was running at only 180rpm. Most of the noise that can be heard now is coming from the condenser cold water and vacuum pumps, also the clicking of the lubricator ratches is now easy to distinguish. www.tunneltug.co.uk
Wow, really, what a difference. The hard knocking sound is completely gone and the engine runs smooth and soft. Well done.
