OutdoorKing Repair Forum Forums General Discussion Forum Power Equipment...Mishaps and Funny Stuff Scott Bonnar 45

Hi everyone, First time to this forum and hoping I might be able to get some guidance. I recently purchased a Scott Bonnar 45 with the intent learn about lawn mowers and be able to work on it myself. I brought this machine knowing it had a clutch bolt missing ( at least thats what the seller told me). The machine itself looks in good knick, but the red clutch part move when started. As you can see in the picture there is a black hole visible and was wondering if anyone might know what this is and what the missing part is that I need? I think it is Engine Shaft Clamp Pin, but am a novice.

Thanks
Thomas

Hi thomas18,

The pin is no longer available but you can buy the engine side and it depends on the engine shaft size as to which one you purchase.

Thanks. Does the missing part appear to be the engine shaft clamp pin shown in the Model 45 parts diagram?

Also, how can I determine the shaft size? Is the mower ok to operate without this, or will I cause further damage? What is the engine side?
