Champion blower help

Recommended Posts

Howdy,

I recently picked up a champion blower and was wondering if anyone had some information on the model and how to tear it down. I took it apart today to do a little cleaning but I couldn't get the fan off and the slotted screws inside the cover were frozen solid (letting some penetrating oil work on them tonight). Please correct me if I'm wrong but it looks like someone peened the shaft over the fan (won't move with set screw taken out). Any info would be appreciated, thanks in advance.

I just finished one of these lil guys, if you hit the nuts with a torch till just the nut is cherry red then quickly unscrew them they come off pretty easy. Also there should be a square set screw holding the fan to the shaft.

 

I also don't recommend taking the gears out but you can take the two screws out of the "lid" and just keep hitting it with WD40 and turning the fan back and forth

Thanks for the video Mars, looks like you've got it running good. Looking at where the shaft goes through the fan on yours and mine (first picture I posted) it looks like someone beat on mine with a hammer. Any thoughts on what I should do about it? I'm thinking file off the peened edges and replace that set screw with new hardware if it doesn't hold. Judging by how mine sounds I need to take a look at the bearings. Any tips?

I'd need to hear it to be sure about the bearings but yes I'd use an angle grinder with a flap disk to get the peened edges down. 

Hold up on removing metal yet that might be part of the fan.. let me check

You can see the set screw in the second pic .  And you can tell what is the fan and what is the shaft hopefully

The more I lookat it your blower is slightly different but that fan shouldn't need to be ground at all. It just needs lots of wd40

Again don't grind it at all

Another correction lol I thought you meant the nuts holding the blower guard on when I said to heat them cherry red. (Been dealing with flooding all daysoy brain is a wee bit tired)

So bottom line is you just need lots of wd40 for all your current issues.

Looks like I have some work to do on that shaft, I'll probably fiddle with it tomorrow afternoon or on sunday. I'll follow up on this thread and let you know how it goes. Thanks again Mars.

 

P.S. After seeing yours I may have to paint mine after I'm done with repairs, looks good.

This is just a follow up to this post in case someone came here looking for information on how to resolve this same issue.

The only way I was able to get this fan off was to go to auto zone and rent a gear puller:

 - You will need to get the five (5) ton gear puller and swap it to using two jaws instead of three, the two ton puller is too small. (you may have to play with the adjustments in order to get the jaws to fit around the bushing)

- The center screw will be too large to sit directly on the fan shaft so get a 1/2" to 3/8" socket wrench drive adapter and put an allen wrench attachment on it that fits the full width of the fan shaft. The center screw of the gear puller should sit in the 1/2" drive adapter perfectly.

- The jaws of the gear puller will want to slip off the back of the fan bushing when you start applying pressure so I used a bar clamp to keep them on.

Please note that this is a last resort, I recommend just sticking with wd40 if at all possible.
