Re-Power: LCT 414 or B&S 14.5 GT

I am the proud owner of an Ariens 924120 - 1024 Sno-Thro from 2000.

However, the only reason I got it is because my neighbor blew the 10hp Tecumseh engine that was on it. He asked me if I would like it for parts.

Heck Yes!

Now I have to decide if I should re-power with a new Briggs and Stratton 14.5 GT (just like the unit I put on my Bolens), or use the LCT 414cc engine that I have. The B&S translates roughly to a 10HP unit (like the HP that the Tecumseh put out) while the LCT roughly translates to 12HP.

I am sure that the B&S would have plenty of power while the LCT could be overkill. However, the LCT is just calling out to be used, and this Ariens is a really nice machine!

Another thing, I already bought the adapter plate to mount a B&S where there was a Tecumseh originally mounted. I don't know yet how the mounting holes on the LCT would line up.

you can also put the30 sho 2.75 top pulley on it if your 414cc has a 1 inch shaft
2.50 is stock non sho
lct rates the safe max rpm 3850 plus minus 50

I am wondering if there are any deals on the B & S engines, like the one that OPE Engines had last year - $220 for the 1450 series snow engine. ???

I'd go with the LCT if it is just sitting there.

Have you been able to put the Bolens/Briggs machine through the paces this season?

Regards, Ted

If you already have the LCT, that makes the most sense if it fits. I have not seen the B&S so I don't know how wide it is on the front of the engine, but the LCT is fairly wide as is the Subaru (so it appears). I've got a 291 LCT on the shelf and there are a couple of gotchas for me to use it in my case. The width is one item I'll have to deal with. Another is the lack of a throttle as that's something I want to see if I can rig up.

A member reported Subaru has exited the small engine business and he is already finding it difficult to obtain parts. There will be no rush by aftermarket manufacturers to produce parts as the numbers are not there like the Tecumseh when they went out. If true about the exit it will be nothing more than a boat anchor in a few years and would stay away from it.

The absence of a throttle control on a larger machine would be a cost cutting measure only.

Good to know on the Subaru engines.
On the throttle thing, I think you're right. Then again it could be some govt thing, you never know. If there's enough demand, someone will come up with one in time (I hope).

My Ariens has the 414 cc LCT engine with 20 ft lbs of torque. It is a great engine. Fires on first pull of starter and immediately shut off the choke and engine runs smoothly. Has enormous power compared to my previous machine's 11 hp Tecumseh. The engine does not sound noisy to me and the controls for choke, primer, throttle and fuel supply are easy to use. The gas tank is small at about 3 liters.

Congrats on the new machine! Especially if it was free!!

I believe that's the model # of mine, a 1024 Pro, 24" bucket. Does that sound right for yours?

If so, one thing I've considered from looking at mine (relative to other engine options) is that the chute rotation controls attach to the cylinder head, bolting to the holes for the OHV valve cover.

You'd need to make sure that the engine would still permit mounting the chute bracket somehow.

It's already pretty powerful as is, with the 318cc OHV Tecumseh. Given the narrow bucket, I think you wouldn't make full use of a ~420cc engine unless you also used a larger pulley, to speed up the impeller & augers.

That way you throw further, and would also process & toss more snow per second, allowing a faster ground speed without the snow overflowing around the side of the bucket.

I've considered trying to make this change on mine. But with that much extra power on tap, I think it would almost be a waste NOT to speed up the impeller. Otherwise you'd somewhat rarely be able to fully load the engine. It was already a fairly high power-to-bucket-width ratio from the factory.

iam pretty sure either member shaw or elaw350 has already done the swap with the 414 420 on a 24
id rather have the oh318 tec engine then the brigs it has more torque should be almost a bolt on
easy to up the engine rpm and over drive it as well
i can load my 28 inch bucket just fine with the 414 even taking 1/2 buckets
more power so nice for eod
