Problem removing Lawnboy Muffler
Lawnboy 21, Model: 8237
I'm trying to remove the muffler to clean it, exhaust ports (and possibly eventually remove motor from the deck).
I was able to remove the nut, blade and other misc hardware with no problems but the small triangular part that retains the muffler is blocked by a round piece on the shaft.
It's not a nut or washer, Actually, it looks like it's part of the shaft ..but it must come off. I've tried tapping it, soaking it with P.B.Blaster, turning it with vice-grips and so far, it doesn't budge. I don't know if it's threaded, should slide off or even know what it is, for that matter.
Referring to https://lookup3.toro.com/Ill/1x/5/5712/80340005.gif it's not shown here but would be between parts numbered 56 and 58
On mine, part no 56 is basically a flat steel square with holes drilled. What is it supposed to be? Could it be that it had a round collar welded to it and mine came apart and stayed on the shaft?
Thanks for any input.
