Have a 21st anniversary greenfield 8hp/28cut that I wish to get back on the road/grass. The rear drive sprockets have worn out and I am looking at replacing them. I am looking at putting the shaft in the lathe to cut the sprocket off and purchase a new one from a bearing shop. My main issue lies with the tapered axle ends where the alloy wheels are keyed on to the shaft. The alloy in the rims has chewed out which has allowed the key to move and has significantly flogged the shaft.
I am interested in recommendations on how to repair or overcome the damage.
At this stage I am looking at welding a new key onto the shaft and carefully grinding it back. The alloy wheels being flogged out I was thinking of drilling,tapping and putting a grub screw on the opposite side to the key to try and hold it in place.
Your thoughts?
