Copper Washers on Cylinder head cover and side covers

<< < (2/2)

Bryanj:
Never noticed copper colouring on any of those, perhaps the zinc plating had not worn off as most of the ones i did were 1st time strip.

Erny:
Reopening this topic - are mentioned washers fine to be reused (after check and eventual flattening /grinding) or needs to be replaced by new ones? HSM does not specify this.

Tomb:
Any copper washers can be re-used if not damaged, copper work hardens so will need heating to cherry red colour and leaving to cool to anneal, they are then soft and should not need flattening/filing as they will do that when tightened down against. Of course this may remove the plating.

I make copper head gasket for my 4 cylinder bikes which I re-use in the same way.

Bryanj:
Back inthe day they were rarely replaced unless leaking

Erny:
Great, thanks
