Troy bilt snow blower

Good Evening.

I wish I had a model and serial number but it has been scratched off completely. Not on purpose I'm guessing but none-the-less.

This machine is a friends and I want to take the auger assembly out. I've removed the bucket assembly and auger pulley easy enough but below the pulley, there is what appears to be a collar. I have no idea what purpose it serves but I think it needs to come off in order to pass the shaft through the housing.

There is a set screw that I have removed but there is a second indentation on the collar that I'm not sure about...no set screw in this hole.

I'm not sure if i should get a puller on it and start going to town or if the whole assembly is supposed to go through.

Also, the pulley key seems to but stuck in there pretty good and I'm wondering if I should just start pounding that out as well. I've included a pic if anyone is familiar with this set up. I've taken a few machines apart in my day but have never seen this setup.

Thanks
Lefty

Key will need to be removed before anything is done. Catch a corner with a punch and walk it out. It's only wedged in there not much else holding it in. As for the collar, soak it with PB blaster or any good rust penetrating oil and then use a puller to remove it. You may need some heat on the collar to expand it some to break the bond and then remove it while it's hot. The bearing below should be replaced since your at it. Best of luck.

yeah if you put heat on it your going to have to replace the bearing........ try removing the set screw and hit it with PB too....... I'm surprised you got the pulley off without a lot of heart ache! Usually this stuff gets pretty rusted on. There is a technique with heat and using paraffin wax that might help. I'd try soaking it and tapping it with a hammer/chisel a few times. Maybe drill a few more small holes to get more penetrant in there.....




I am deathly allergic to shovels!

Thanks guys. Yes, it is very close to the bearing. And I can't ruin it because like I said previously, I have no legible model or serial number for the machine and have no idea how to get parts. Just curious, what purpose does that collar serve? Is it retaining the bearing?

Thanks

This looks like a Bolens design that Troy-bilt used. Does yours look somewhat like this:

Public Surplus: Auction #1108403 -> maybe you can start with the model number listed there.

I feel your pain. I went through this a while back while trying to get a working snowblower out 2 Bolens 824 snowblowers. I had to cut off the auger pulley as well as that collar, but only because I had those same parts from the other machine.

I'd think that you could just pick up a suitable collar at the hardware store once you determine the correct bore size, no?

I was surprised that the pulley came off so easily as well. I just gently nudge it with a bar close to the center and it came right off.

Here are some picks of the machine, including the scratched up id tag.

I was right, it has Bolens lineage. Looks like it's a 42010 from your picture with the mangled model number. You can get the owner's manual here:

Thanks DB. That looks like it might be it. Is the part in question a spacer, collar? Honestly, it doesn't look like it does much except bust my balls. I can't figure out why it is even there.
