Engine swap please

Hello

ive been trying to fix my Tecumseh 6hp (h60) for a while and just cant figure out what the problem is. im tired of this. it now runs like crap and i think the crank is bent. so maybe it's time to swap the engine,

I see many people use the Harbor Freight predator engine. is that any good ? sounds like cheap made in china ?

i also found someone who installed a Honda gx200 to replace an h50. would that fit on my ariens ? Im a big Honda fan. id rather pay more for quality than buy the least expensive for ...


Any other good engines that fit on this ? ive done engine swaps in cars, so i figure i can do one on a snowblower


I presently have a 1972 Ariens 6hp (h60)

Model 910995 serial 004754
sno-thro attachment is 910995 serial 083666
there are some pictures in my profile

thanks
Guess ill be using my shovel for the snowstorm today

you'll love the harbor freight engine. All the snow engines are made in China now so wouldn't hurt trying the harbor model. I've done 4 of them on machines and have been very happy.

Current machines-
1978 Bolens 8/24 (Loncin 420cc engine upgrade)
1986 toro powershift 6/24 ( 212cc Predator upgrade)
1988 Simplicity 860 (Predator 301cc upgrade)
1995 Honda HS 621

Many members on this forum will attest to the 212cc Predator being a viable solution; however there are others who will argue its use.
I believe that it's an easy and worthy option. You can get them cheap if you find them on sale and use a coupon, plus they bolt right up to the mounting pattern. The larger Predator engines have a larger bolting pattern though.

But as with any product, shop around before settling on the first option. Check ebay and craigslist for used motors, just check that they are in working order. Or check craigslist for anther blower for a low price...may be somewhat rare during this time of year, but they are out there. You may find a non-working blower for $50 because a wire isnt connected...easy fix and now you have a better blower.

I have done two HF Predator engine swaps on my machines and I'm happy with them. Start first pull every time

I have never done a Predator swap and know only what I have read here.

Depending on the diameter of the output shaft on your engine, you may have to buy a bushing to adapt your pulley(s) to the Predator engine and new longer or shorter belts MAY be required. There is a wealth of information on this forum of people who have done the swap successfully, you just have to search for all the threads for the correct information. Relocation of the chute rotation handle is also a possibility that has been covered here. Good luck, it has been done with great success.

Experience is something you don't get until just after you need it.

Many have done the harbor freight Predator swap with good results. I hear you on not wanting to support China though. I have repowered a few blowers with Honda engines and they have run excellent. Most of the Hondas I bought used off craigslist and they were easy to bolt on and ran awesome. I wouldn't hesitate to go for that option. In fact, I'd rather find a used Honda than buy a new Predator, just because I'd like to avoid supporting China.

Will the Hondas last any longer than a Predator? Who knows, but it makes me feel a little better.

i would prefer a honda (or any other japanese small motor such as subaru,toyota,nissan, if they make small engines).
i have a honda mower and that thing runs great. a small pull on the cord and it purrs. never done anything other than change oil every year and spark plug when its fried.
but i am open minded to any other swaps that are reasonably priced.
any other swaps that have been done ? im sure there are many !

whats the max power i can safely put on my snowblower ? i heard many people swap the 6 hp for the 8 hp. is that safe for the auger and other parts ?
i found a honda gx240 (7.9hp and 13.5 lb-ft). is that too much ?
basically i just have to find an engine that i can fit the shaft on my snowblower shaft ?

As they say, you can never have to much horse power. Most small engines operate around 3600 RPM and the extra power will lessen the RPM drop when going through heavy snow or end of drive way piles left by the plows.

One of the forum members (Geno) put a twin cylinder Honda 20 hp? motor on his snow blower and we all waiting to see his monster at work.
