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

In theory it should work.  I don't undrstand how it realy works. Snow blower housings are NOT perfictly round. Only the low spot  (spot with the closest distance with housing )will get wiped. All impeller blades will be worn to this low spot during the brake in period.  So in reality it is never a clean swipe , Only the low spot gets wiped clean. The other areas will still have a gap. How big a gap will depend on the out of roundness of your housing. This area the impeller scrapes clean also scraps off your paint . Your housing will then rust away.   Then what.   Buy another  housing or

BLOWER !!   I believe Hondas pump so good because there housings are rounder and there impeller clearances are tighter from the design of the unit.

I just put a kit on an old Ariens and I can't wait to try it out.

The housing seems pretty even all the way around, but it is not broke in all the way yet.

There was a low spot where the chute opening was welded to the cylinder, but I ground that down first.
It is welded on the outside, so grinding a bit off the inside didn't seem to matter at all.

As for scraping the paint off,  this is a 33 year old snowblower, so it didn't have any paint on it anymore anyway.

Now there is something I didn't do; use a magenetic mount and dial indicator to measure the impeller housing runout. Or for that matter the tolerance on impeller blade length. However, a bit hard to do without removing the belts so it can be rotated by hand. Are the Simplicity impeller housings round?

Don't be silly they are triangular, a Simplicity exclusive. LOL

3 isn't as good as 4, but it is still better than 1.

Posting a question here is a bit like asking a question in a third grade class for the slow kids.

Round, in contrast with 'out-of-round'. That Is one of the tolerances on impeller/housing clearance.

Yeah, does a third grader know how to read between the lines?

Here is the definition as best as I can define it. It's a tough one like the meaning of "Maldita" in Bisayan

Drongo: A person who couldn't get a clue during the clue mating season in a field full of horny clues if he smeared his body with clue musk and did the clue mating dance.

The problem is that they don't have Barry White.
