Blade plate removal?

[barney98]

Does the square iron plate that holds the blade in place, is it removable? And if so, is it threaded?

Are you talking about the blade adapter at the bottom of the shaft that you bolt the blade to? It's been a few years since I've had a Lawn-Boy, but that adapter isn't threaded or welded on. Sometimes they are just stuck on pretty good from a bit of rusting over the years. Some PB Blaster or other good penetrating oil should help loosen it. If that doesn't work, then you may have to use a little heat as a convincer. Just not too much. You want to heat the adapter, not the crankshaft...

One more thing. Once you do get the adapter off, a little anti-seize compound will be your best friend for future removals. Just brush a light coating on the end of the crank before reinstalling the blade...

Yes, the plate that the blade sits in t keep from moving.
Thanks for the reply; I just needed to find out if it was threaded on or not. Used some Liquid Wrench and a gear puller but the plate started to bend so I stopped.

I have a self-propel with the pulley on the shaft that came loose, and I've had to remove a lot just to get to where the set screw can be reinstalled

You may end up having to get a new one once you get the old one off. Not sure why, but seems like Lawn-Boy has that issue more than other brands. But once again, use a little anti-seize on it before remounting. This will also five you a chance to clean the muffler and exhaust ports if your Lawn-Boy is one of the older 2 strokes...

After removing the blade, hit the edge of the plate with a hammer to spin the plate on the crank to break it loose. If it is really stuck , heat up the collar on the plate and hit one of the plate edges. It should break free then. When reinstalling the blade, torque mounting nut to 45 lb ft.

Thanks for the replies, but I worked around it without having to remove the plate.
My next question, the set screw on the pulley...I was looking for a divot for it to either set into or thread into, but there wasn't one. So I just snugged it up against the shaft. Has anyone else seen this??

I would add one thing: hit the blade adapter in the direction of rotation.

This design (making the adapter difficult to remove without damage) is one of the few areas where Lawn-Boy blew it. :confused2:

if the set screw did not need a threaded hole to go into they would have made it that way.As long as it holds everything is allright right?When it lets go not so good.
