228b rattle

#1

Post by hiddenhider »

So my 228b has a rattle when running. Now somewhere way back in the back of my mind I remember something about the eccentric block sometimes making a rattle; it runs fine and has a good gurgle at a quarter turn.

I guess I should pull it down and see what’s going on; any ideas on what to look for?
Thanks, John

I'd try moving the cleaning lever a little and see if the noise changed. A rattle might be the pricker rod vibrating. Some have suggested rotating the generator some, but if it is running ok, then taking it apart might introduce new issues.

I think you're referring to the classic, iconic 220/228B noise. Some have described it as "slurping", but to me, it sounds more like a hot engine cooling down after a long climb or an old steam regulator warming up.
It's priceless until someone puts a price on it.

It ran fine two days ago with no noise at all, ticks just enough that the uninitiated would think there was something wrong with the audio. 🤣
