OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers SB45 Rear sprocket stuck !

hi all,
Working on my second SB45 rebuild, and having troubles removing the lower roller sprocket.

I had removed easily on my last build, but not having much success. I have a 75mm gear puller, and doesn't want to budge (and noticed its started bending the sprocket. Any other way to remove without buying a larger puller?

thanks

Sounds a tad odd but you might have to apply a bit of heat to it.

Cheers,

Yup. Try heat, quality penetrating lube - CRC 5-56 is my favourite - then heat again.
