OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers SB Drive Assembly

It's a model 33 serial# 10819 17". I've disassembled the whole machine and newer pic's are attached.

Looking from the inside, it would appear the assembly is on a keyway so I don't think it will unscrew. But from the back it looks like it's screwed on???

After loosening the locknut and jamming the magneto from turning, I gave them clutch a good firm twist (probably harder than I should have) but it wouldn't budge.

Thanks for the forum and your help.




Cheers
Ian
