Engine Swap

Hi everybody,

I have a 1987 Toro 521 with the HS50 Tecumseh engine that I'd like to replace with a newer one or one barely used. My question is what Tecumseh engine that isn't the identical model to my old one would fit my snowblower?

The engine I currently have is #HS50 67259F and it's 5 horsepower.

I have seen used 5.5 horsepower Tecumsehs that have the LH designation.

***Would an LH fit?

They all look like they have the same mounting holes as my old engine but wonder if there would be any other problems?

***If an LH wouldn't fit, would an HSSK 50 fit fine?

I know I'd have to have a 3/4 shaft and 3/8 shaft screw on the newer replacement engine to fit the original pulley (which I don't want to replace) on the blower.

Thanks for the help,

Rich

Any Tecumseh 5-6-7 hp engine will be a direct Bolt On Replacement, as long as it has the same size Crankshaft Diameter. Easy Peasy.

Also you have to make sure it's not a double shaft engine, If so the replacement will need to be also. Tecumseh came with single and double shaft.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.
New 2017 Ariens Deluxe completely rebuilt after losing a fight with a forklift.

521 is a single shaft application. Any 5-6-7 Tecumseh with the same size crank will work, even a double shaft, You just don't use the PTO, and cut off the secondary shaft if it is in the way of the belt cover.

Good to know, thanks. I'm glad it sounds like almost any used Tecumseh should bolt on without any issues. I do not want a Predator which I feel has just the cool name going for it and I grew up USA/German or Japanese products only. I want something with real steel in it but unfortunately those days are about extinct so I'm going used and in good shape.

Are you sure Jack, Not positive but I thought the one My girl has was a double shaft, I may have been thinking of another blower but I thought it was hers. I'm going to have to check on that one.

The honda clones (predator to name one) are arguably better engines then tecumsehs. Its nice to know that tecumseh was made in america though.

Definitely a simple swap from one tecumseh to another small frame tecumseh.
