Why is my generator "clunking"?

My 8kw Onan Diesel generator has been working fine, when I push the pre-heat switch it goes "tickety-tickety" and after about 15 seconds fires right up.
This week while running it, it started to emit more of a "clunking" sound, very rythmic and regular (and pretty loud). I shut it down, today checked the oil level (clean and full) and when I pushed the Preheat button again to try staring, this time it gave off the "clunking" sound instead of the quiet purr of the normal "tickety-tickety".

Any ideas on what might be the problem? I didn't leave the preheat button pushed long enough to try to start it for fear the clunking was ruining something.

Thanks in advance for any ideas / input

Difficult or impossible to diagnose "clunk" virtually. However.....

Have you checked the mounting attachments? Maybe it is simply moving around when started and hitting something?
