I recently purchased an Atco Groundsman 34 (circa 1975, I think) to strip, refurbish and rebuild as a bit of a springtime project. The strip down has been progressing well, until I reached the point of removing the sprocket from the cutter drive control. Can anyone tell me how I go about removing the collar (unsure of the correct term) to allow me to remove the 2 sprockets behind it, circled in pictures below.
Also, when testing the mower before commencing the strip down, the force of the clutch engaging would cause the collar to jump from its disengaged position to engaged, is this a known issue and is there a way to stop it from happening?
Thanks for any assistance in advance.
