You may recall a few articles ago I wrote about the lost art of lubrication and gave some examples of what could go wrong with a lack of lubrication. More recently I have been involved with a situation where it wasn’t the level of the gearbox oil that was the problem, but the oil itself. What this led to was becoming acquainted with people far more knowledgeable on the subject than me and it became a fascinating learning curve. As they say, everyday is a school day.
