Question Ariens ST524 :: 5HP :: Improve Throwing Distance?

Snowblower: Ariens ST524 snowblower (model: 924046, 24", 5HP, serial: 001247)

I purchased the blower used. I've used it a couple times last year and found it would throw snow about 3 feet tops, perhaps less. I changed the drive belt and it still did the same thing so i figured the 5HP engine is the issue.

Is it possible to upgrade this engine so that i can get better throwing distance? Or perhaps their is some form of maintenance i should look into first?

All ears.

Thanks

If the impeller is running at proper speed, the impeller clearance is the next thing to look at. many have too much clearance to begin with and it does not take too much wear and it is unacceptable... IMHO

Throwing ability

In addition to what's already been noted, check the shear bolts along with the auger and impeller bushings. I've seen both cause issues throwing but I have to agree on the others to check out first. Other thing would be the amount of snow being blown. If you have little to no snow, that also won't blow well with a 2 stage blower. You probably want at least a couple of inches to effectively blow. Dustings work best with a single stage, real snow works best with a 2 stage.

The engine most likely isnt the primary cause of short throwing distance..
(although it can be, if its out of tune or otherwise "weak" for some reason..)
but when this machine was new, it threw snow fine..and it still can again! without replacing the engine..replacing the engine is the *last* thing I would do..
(you could replace the engine and *not* have it fix the problem! if the engine is not the primary cause..which it probably isnt..)

Engine condition and belt condition/setup is the first thing to check..
even if those are all good, many (most) older snowblowers (of all brands, not just Ariens) are well-known for not being able to throw "wet" slushy snow very far..if its "dry" and fluffy snow, no problem! but the wet snow can be a problem..its because of the gap between the impeller and the chute wall..that problem is also easily solved! check out these threads for more info:

Wow, Impeller Kits! I never knew about such a thing.

I will give that a try first and see how things go come winter time. I think i have some rubber floor mats i can cut up to use and my box of anchor screws are around.

I did replace the Auger Belt last year (didnt get to try it since we didnt have snow).

Much appreciated guys!!!

Shear Bolts
Auger + Impeller Bushings

I will locate the manuals and figure out where these are. I will get back to you.

Perhaps it is normal for a 5HP engine but to me the auger appears to spin quite slowly. Again i did replace the auger belt and it feels quite tight / secure. The throttle is set to Fast.

How does one determine the correct spinning speed of the Auger and Impeller?

The engine should be spinning at 3600 RPM, the auger and impeller are at fixed rates other than the engine.

So if the engine is spinning at its proper "full" rate, then the augers and impeller should also be spinning at the rate they are intended to spin.
Engine speed directly controls auger/impeller speed.

I bought one of these earlier this year:

another vid from the same guy:

How to use - TREYSIT Sirometer - Drehzahlmesser

I dont remember where I got mine..
I thought it was Amazon.com, but I dont see them listed there now.
found a few other places:

Tachometer (Treysit Sirometer) 19200 Order now for same day shipping. 365 day return policy. RepairClinic.com

19200 Tachometer

handy device, and works well!

sorry if you misunderstood me. i wasn't implying that you put a new motor on your rig buy look at the vid gustoguy posted because he also has an auger kit on his rig
