Anyone here have pictures of those impeller upgrade kits?? I was checking mine out after the last storm, and looks like I have over half a inch of clearance between the impeller, and the housing. Im thinking of adding some form of rubber belting to take up the slack a little. At least on a few of the impeller blades. Also... so do you realy need to do all the blades? or you think just half of them would be fine? I just hate to overtax the little 5hp engine on mine.

I've been using the impeller kit (Clarence's impeller kit) on a 5hp Craftsman since the the beginning of this winter season. It doesn't seem to "overtax" the motor from what I can tell. The snowblower is thirteen years old now. I took the impeller out when I put the kit on, which made it easier to install, but that was all done in the autumn.

She is ugly and needs some new paint, but shows no mercy for anything in front of her. The HM 80 threw a rod so I upgraded to 11HP GX340 clone.

If you do half the blades ,usually people think at 180 degrees,.... well that would introduce a two times vibration per revolution which would be like a coupling misalignment as far as impacting the bearings.

I'm perplexed at trying to calculate the weight imbalance of the impeller kit when it weighs 4 to 6 ounces estimated per set but I agree I would strongly suggest putting one at every impeller blades to prevent clogs in wet snow. Though I would not be overly worried since every bladeful would potentially be of different weight namely one with a chunk of ice and the other none, uneven packed snow along the side bank, so I think too much weight (pun intended) is given to that aspect. Again JMHO.

Can you elaborate? You're not suggesting that if you were installing the kit on only two of the (four) blades, they should not be on opposite blades?

That is one sweet upgrade to your impeller ...what did you use for the rubber source.

That was an actual Clarence kit. I did another one using the baler belt from Tractor Supply as it was a lot cheaper and the rubber looks the same.

Shyrp, with that Honda Clone, what size shaft is on it? I ask because I just did a Predator upgrade using the new 8hp 301cc preadator and it has a 1" output shaft...very hard to find pulley's at 1" bore especially for the smaller drive pulley.
did you have similar trouble?

It was 1". I had a 2-1/4" I think for the wheels. I believe Tractor Supply has some smaller ones on their display at our local store here. Also give this guy a look. Someone had mentioned buying some from him and I bookmarked it.

Wow, thanks for the link Shyrp! he has a 2.7" with 1" bore...that is better than the 3.35" I ordered yesterday - that was the smallest I could find.

Before and after pics of one of the blades on IH Cub Cadet 328. I did all 4 blades last week, but haven't had the chance to try it out on a good snow. We had a good snow yesterday morning, but I had to work. Snow turned to rain then only had slush to shovel when I got home. All 4 blades had a similar gap, ~1/2". Used 4" wide baler belt from Tractor Supply. I might do the same mod on my primary snowblower on a garden tractor.
