Question Need to replace 8 HP Sears engine

Hi, I just toasted my engine model # 143.796092. Its a decent machine that i got for free, so im thinking about replaceing the engine. Im doubting sears sells engines (although i do see all the parts available). Anybody got any suggestions as to where i should be looking or a drop in? Thanks.

Craftsman uses tecumseh engines. Your engine is a Tecumseh engine model HM80-155366N. Thats a reference for the experts of this forum, so they can help you out with a new model. How did you toast it?

Thanks, I just put a new carb on it, ran fine without snow, but i was clearing some heavy stuff today and it locked up after about 20 minutes of work. It did start to smoke a bit and i could hear some kocking, but I was sick of messing around with it and figured the snow gods would see me through. Ooops! Guess that'll teach me to pray.

sounds like you locked the engine up..... or already had damage, did you make sure the oil was fresh and full? sears does sell engines, more expensive then a small engine shop or online source, you can use any engine on it, as long as it'll fit and work on it. sears doesn't use just tecumseh, they use hondas, briggs, kohlers, even seen a robin once.

My Tecumseh look-up indicates that there is no exact replacement engine available but there is a shortblock, part# 756318A. I'm sure, however, that you can find a suitable Tecumseh replacement engine to use through a dealer. Just bring your engines' crankshaft dimensions (diameter and length) and whether or not it has a headlight or heated grips and they'll most likely set you up with what you need. The new engine may be either a 9 or 11 horse but the specifications should otherwise be the same. We sell many 11 horse engines at my shop as replacements for the older eights.

I believe 8 HP were discontinued and replaced with 11 HP. They do make a 9 now as well. The 11 or the 9 are bolt ups where the 8 or 10 used to be so either will fit nice. Some of the older 8's had a larger diameter crank on the PTO side so you best check that out first. If it is larger you can buy an adapter sleeve so your pulleys will fit.

What about a 13HP replacement? I have seen a local small engine guy using the 13 HP clones for a couple of years to replace the 8HP engines on log splitters, and claims they are excellent. Where can I get the adapter sleave mentioned to use a 1" shaft motor in place of a 3/4". Any idea where to obtain generic 1" shaft pulleys in varying sizes?

Grainger is a good source for pulleys. The 13 horse may not work on this application as there may not be enough room for the extra bulk of this engine versus the eight.

I live in Canada. I buy adapter sleeves from a bearing supply company (NSK)(Raeside equipment) . 6 bucks each.
