Craftsman high wheel trimmer mow ball replacement

Britcheflee · May 7, 2009

I have an older craftsman high wheel trimmer - 917-773422 - the mow ball needs to be replaced as the old one sheered off its mount (the plastic part only) I have the new one ready to replace but having a devil of a job doing so. There is a bolt at the bottom with what looks like a hex nut - but this is very shallow and nothing seems to grip in it - am I doing the right thing by trying to remove that bottom nut? Can I cut away the old plastic without damaging anything?
Hope this is enough information to get an answer - I have a feeling there might be a bearing in there which is seized up as the plastic part does not rotate much - it is soaking up some PB Blaster at the moment.

As I recall the bolt that you speak of is an Allen head capscrew, left hand thread if I recall correctly. You may cut away the plastic and popssibly get a vice grips on it, or a small chisel and work it out carefully. When all else fails that piece is available as a complete unit from Sears as well as MTD. Good Luck

Thanks, the allen head seems very shallow and I cannot get an allen key to seat well in it - I will try carefully cutting the plastic away with my dremmel tool.

thanks,

The Allen can be very shallow if the ball was worn down badly as the Allen head will start wearing.

Ah ha! That makes sense. I could not work out why they would make a retaining nut with such a shallow depth for the allen key to go in.
