Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I'm replacing a worn worm gear on a 1988 Lawnboy snowthrower Model 55382 ST824. I tore the gear case apart but had a hard time removing the bearings on each side of the worm gear. I finally had to grease the auger shaft and pound on one of the bearings until it slid off. During this process, I nicked up and damaged the bearing. I also had to pound off the worm gear.

Is there a better way to do this? Do the bearings come apart before they are removed? I'm not too worried, at this point, about the removal but definitely concerned if I have to "pound on" the new worm gear and bearing when I put them back on.

Any comments or suggestions would be greatly appreciated.

Thanks,

Mark

Borat,

Thanks for the reply.

The ends of the shaft where I had to hammer the bearing over had some rust. I assumed this was causing most of my problems. I just wanted to verify that this was the only way to get the bearing off. (ie by sliding it up or down the shaft). I wasn't sure if there was some way to loosen the bearing before you slid it off the shaft.

I think I'll try removing the rust before I apply the new bearing. If that doesn't work, I'll try freezing the shaft and warming the bearing.

Thanks again,

Mark

The rust is what's probably causing the resistance. 

On a shaft like that, I use the "shoe shine" method to ge the rust off.  I cut pieces of sand paper a couple inches wide and pull back and forth across the shaft.  Rotate shaft and continue.
