Rear Main Bearings

[David Stepney]

To be fair, there is still a bit of rumble at tickover. It is noticeable now that I have got the carb sorted and have a decent 'andante' tickover rather than the 'allegro con brio' one that I did have. My engine is the sort with a roller/ball bearing front bearing combination, so I presume that the rumble is the front roller. Anyway, it goes as soon as the revs are picked up, and, given that it is a 'cooking' engine with, according to the handbook 12 bhp at 2600rpm I am inclined to wait until the engine needs a complete overhaul before doing something about it.

Whilst thinking of funny noises, I had no idea that a worn fan bush could make such a noise until I replaced mine! The "tin tray down stone steps" noise that I thought was part of the nature of the beast has gone completely.
