Ye Olde Ariens Snowblower

Once again my old late-70s Ariens has cheated death. The other day it ate up a big chunk of tree branch, which jammed the blades, which threw off a belt, which caused an already damaged pulley wheel to get yanked out of place, which made everything get real angry and violent, so I shut ‘er down. And when I opened it up for some emergency driveway maintenance, I either lost two bolt clips that hold the front half to the rear half, or they were never there to begin with. Either way, when I put everything back together again, the whole machine felt loose and squishy and was shuddering when I tried to engage the blades, so I shut it down for the day and shoveled. BOO!!!

Opening it up this morning and taking a proper look, I saw that the pulley hub on the main sheave wheel was all messed up. Cracked right in half. It didn’t look fresh, and I’m betting it’s been that way for at least a decade (the ol’ gal’s always been a bit loud and clangy).

Now, it’s completely possible this is an obtainable part, but I am not only cheap, I’m impatient. I wanted the machine functioning today, so I squeezed the hub pieces back together with my vise and strapped on a random hose clamp from my old ’66 Mustang. Since this is sort of a half-assed solution, I didn’t try to tighten the hub down with the allen bolts (they’re frozen un-tightened anyway). There’s a keyway/groove in the hub that’s keeping it pretty well in place. I declare it to be “good enough.” I also used some Mustang fender bolts and bolt clips to secure the front of the snow blower to the rear and it feels really different. Much tighter & more solid-feeling machine. I sort of hadn’t realized how loose and saggy it had been before.

Anyway, it started right up, I engaged the blade, and everything’s coming up roses again (and by roses I mean brown icy slush shooting into the air). The hose clamp seems to be doing the trick and didn’t cause any imbalance (or too be more precise, it didn’t make any of the existing imbalance any worse. Ho-ho). We’ll see how long it holds together. If this sort of repair work keeps up, I’ll have to consider putting a running pony emblem on the blower housing.

I intend to pull this machine apart this summer and give it some much-needed maintenance and attention (for instance, this video makes me want to take a good look at the friction wheel). Despite past inconveniences and exciting adventures, it’s a nigh-indestructible machine with a lot of power. It outclasses most modern snowblowers I’ve seen and I want to keep it forever. Maybe I’ll even spend a few dollars on it if I have to. Heh.

  1. Dear Tom,

    You sound like you have a lot of experience with snowblowers. I need your advice.

    I have a relatively new Ariens snowblower. It doesn’t have a problem – I do.

    The auger turns and the wheels spin but I have to force the machine through the snow, even if its just 4″ high. Takes me hours and I’m drenched in sweat.

    Either the wheels spin or going is very slow.

    If I press down on the handlebars the auger lifts up and there’s no improvement anyway. And no improvement if I lift up on the handle bars to put more pressure on the wheels.

    What am I doing wrong???


  2. I have a 1980 Ariens 524. Bought is new. What a great machine for our Michigan winters. I just re-powered it. The original Tecumseh 5hp expired from lack of oil, my fault on that. Ordered a new 7hp overhead valve Tecumseh Snow King online. Bought the electric start model.

    The new engine bolted right on, using a sleeve to adapt the engine to the original pulley. Bought that with the engine. Easy job. This new engine is incredible. Starts first pull every time, just pull slow and easy. Tried the electric start and that works fine too, but don’t see the need. Quieter and smoother than the old 5hp flathead. The extra 2hp makes a difference too. Had 10” fall last week, heavy and damp snow, ran right thru it a speed 4 (top is 5) didn’t bog or slow down like the old motor would do in heavy snow.

    Again, a realy great machine. Nothing like it in the neighborhood.
