Ariens 8526 Tecumsech LH318SA R.I.P.

It happen 3 minutes after start,
I check the oil, and regular check up before start, no problem.
Day before Ariens was working for 2 hours,
without any problem.
What should i do, look for replacement engine or look for use snowblower.

Wow, that is a bad one. It got the block, the sump and the cylinder walls. Not sure I have seen that much damage before. Harbor Freight has the 212cc Predators for $99. Those are around 6.5 - 7 HP and work well for 24" blowers, the next size up they have is the 301cc engine rated at 8 HP and that is more like $240.

You could also look around and try to source a different engine from somewhere else. You could check craigslist and look for a deal on a broken blower. Sometimes you can find a blower with a blown front auger gearcase for cheap.

Please direct all snow blower questions to the forums and not to me with PMs.

Agree completely. Easily fixed for under $200 with either option there..... probably $50 for a broken one with a good block/engine




I am deathly allergic to shovels!

Ouch, sorry, that's nasty.

One consideration would be timing. You could probably buy another machine off Craigslist in a day or two if you wanted.

Doing a new HF engine swap may take more time and homework. If there's a big storm coming in a few days, that could be a problem. If you buy a new HF engine, or similar, you might need to make something to get a shroud around the belts, for instance. You might need different length belts, depending on the location of the crankshaft.

Now, looking at the model number (implies perhaps an L-head 318cc), if this is basically the common Tecumseh L-head 318cc 8hp engine (formerly called HMSK80), those are plentiful. You could buy a used cheap-brand blower with one of those engines, as a source. You'd want to make sure to buy a donor machine with the single-output version of the engine, not the style that had two output shafts. This would likely be an easier swap than a HF engine, as the donor engine is already set up for snow operation, etc.

If it's a recent machine, in nice shape, it's probably cheaper to replace the engine, vs buying another good machine. If you wanted to go that route, and wanted to use a HF engine, perhaps you could buy something used & cheap, to help get you through the winter, while you do the swap? Then sell the "new" machine once you get yours going again.

marki, If you still have the Platinum 28 from your previous post on 3-14-2015, you've got time to swap this 8526 to a new motor.

https://www.snowblowerforum.com/forum...mendation.html

I'd seriously look at this motor
Small Engine Surplus.com LH358XA-159493 Tecumseh 10 HP
You would have the carb heat box, fuel tank/mount and line, mitten handle for recoil you could swap directly from the 8.5 Tec.. Even if the bolt pattern was different for the 10hp, the Ariens tractor body will have holes already drilled. Grind the old studs off, some bolts and nuts. Trim the taper off the crank, buy a 1" drive sheave, 7/8" auger sheave, set the gov down to 3600rpm.

Did your machine require an alternator? For lights or heated grips. If so the Predator 6.5 might not be the best choice.

NR racing torture tested a Predator 212cc and it was able to hit 5500rpms in stock form were it would go into valve float since the stock valve springs could not close the valves fast enough. The flywheel however is unsafe and will not handle much more than 4000 rpms and a billet forged aluminum flywheel rated to 8500rpms can be had for $100. A Tecumseh Snow king engine would totally grenade at 4000 rpm let alone 5500 that the Predator 212cc engine withstood.

Charging coils are available from a couple sources, just need to search.
