Not heard of that as a problem on Ducs, and as its only ali wouldnt it torque out.
Still need Help
Kev

Did you make sure the small dowel was still in place ? Did you smear any liquid gasket on the o-rings before assembly? And clean off any old stuff?

Is the compression still good?

[Screwy]

Probably of no help as I have never had the head of a belt 900 Duke but it sounds very like the bevel duke in construction , Is it possible one of the O rings has moved , been displaced on re-assembly and has been nipped between the head and barrel ? This happened on my old Darmah and caused a leak very much like the one you describe .

[Red-leader]

Zimbo it all came away clean with no sealant of any kind present, so it just needed a little clean up with brake cleaner and put it back together clean. Is there supposed to be anything on the faces or the O rings ?

Scewy it looks like its coming apart again to make sure, but I dont think the rings would move during assembley as they were a good fit in the recesses.

Anyone done this and had complete success, Am I just un lucky

Kev - i take it you did use the green 'silicon' rings? not replace them with black rubber ones? dumb question i know - the green ones withstand higher pressure than the black ones

having just replaced the vertical head on my SS you havent instilled me much confidence but havent had a problem haveing the heads off three times now- i hold the rings in with a smear of grease when placing the head onto the barrell
