MarkCR750:
Is it easier to wait until the wheel is built and then change the bearing Mike ?, I don't know if the 550 is the same as the 750 but on the 750 the retaining ring is centre dotted to lock it in position, I took a fine drill and drilled out the centre dots , I'm not sure if there's another way but someone will say if there is .

Thanks Mark, i wanted to strip it down so i can have the parts blasted and powder coated so it needed to be done before the wheel is assembled. I've now got it stripped down and the bearings removed, ended up holding in a vice between 2 pieces of aluminium to protect it. I made a tool to remove the retainer ring.

Valentinik:
My primary and cam chains came from DS today so tonight I put the crank into the top half of the crankcase. Hopefully during the weekend I can fit the bottom case and get it sealed up.



Valentinik:
I have some  loctite si5980 sealant, will this be suitable for sealing the cases together?

If not, I need to buy some hondabond to seal the cases, is there a specific type/strength which is the correct one to use?

Trigger:
Me thinks that SI5980 is just silicone sealant, you want something that does not dry.
Hondabond or Hylomar is cheaper, it needs to be a thin layer or it will squeeze out in to your engine. I always put it on the case and scrap it with a plastic card, leaving just a tacky surface.
