Hi grumpy, Pauly80 and Kempe, well at long last it seems we have got an great archive for removing the rear roller and ring gear of the SB 430 and 590 Diplomat.
I think Pauly's old man needs a mention also, as he helped immensely with the pulley removal. grin
It would be great if we can have some detailed pics of the new replacement steel ring gear....grumpy is right in his assumption, it is purpose built to fix the original prob with the cheap nylon gear...I honestly don't know what Scott Bonnar were thinking when they designed that piece of #*%$ .....oops! I guess I'm not being very "Diplomatic" lol
cheers2
