Does anyone know the size of the hex in the top of the GS500 damper tube? A feller I know has one that's spinning with the 6mm socket head bolt, he's loosened it with a rattle gun but it won't come out completely.
I seem to remember when I did my seals that the damper tube had a hex in the top, and it should be easy to make a tool out of a bolt head to fit in the hex to stop the rod spinning. Size across flats anyone?
In the past in this situation I've used a length of wooden dowel to push down onto the damper tube to stop it turning, but a 'proper' hex tool would be a more elegant solution eh?
(Or more pragmatic, just carve a tapering hex on the bottom of a length of dowel).
Size?
Ahhh.... it was mentioned in Baltimores video on Youtube, wasn't it? I remember it was something like "slightly smaller than 3/4"", but maybe Sledge said it was 18mm?
Sorry Jools, just woke up and I'm working from memory.
Well big boy, 18mm is slightly smaller than 3/4" so that sounds like it, ta mate.
(I'd better check the vid too.)
Well ya gotta laugh eh? On the youtube clip EXACTLY where he mentions the hex size, the sound drops out!!!
I think earlier he mentions 5/8th... Hasn't the penny dropped? Haven't these fellers heard that Japanese = Metric?
Just to finalise this question. The size is: 23.7mm or 15/16". A bolt this size fits into the top of the damper tube and stops it spinning whilst undoing the lower slider socket head screws.
I put together a rod made from an old Norton wheel spindle with a 15/16" AF head, and a length of steel tubing. I drilled and pinned these together. The rod needs to be at least 450mm long.
