Title: balance damper PNs 13401 and 13401a - ever replace?
Post by: Lucky on July 17, 2019, 13:08:05 PM
Has any replaced your balance dampers, left and right, in the 800? if so, what conditions lead you to do so, and what results?

I've got strong vibrations from 3400-3900 -- which is right in prime cruising speeds

If you are talking about the rubber collars that the through bolts go thru to attach the engine to the frame, then the torque is something like 18 or 24 foot pound - very light tension. Have you tightened them, recently ? Refer to the maintenance section for correct figures. loosen them off , run for a minute or two to settle, then tension to the correct value.  :)

Thanks Paul,
Good info, but these are internal parts --

BUT, i'll check those settings on the mounts, as well

The "Balancer RH" part number 13041-1112 and it's left-handed counterpart 13041A-1112 are large steel balance tuning weight/fly-wheels. If these need replacing your engine is seriously knackered.

I think that you are talking about the "damper" a star shaped rubber component inside the engine, part number 92075-1748. I doubt that anybody has ever stripped an engine to replace these.

The much more likely cause of your problem is the engine mounting rubbers. Try replacing these. It looks like an easy job and the parts don't cost much.
