What your looking for, for ease of installation, is the crankshaft diameter, the height of the crankshaft and the base bolt pattern.

You can find this information on any engine spec sheet, usually in pdf format.

Many brands out there .... Predator, PowerMore, B&S, DuroMax, Xtremepower, etc ......

 

Thanks! I have the mech dwg for the Tecumseh HMSK100, that spec the bolt pattern, shaft spec, and height to horizontal shaft. Trouble is, I am having a hard time finding an engine out there that matches the HMSK100 specs. I looked at a couple of Predators and no dice. Does anyone have make/model recommendations. I cannot be the only one out there with this issue.

Thanks in advance!

 

You sure something like this won't bolt right on.......

unfortunately all modern replacement engines in that size range use a different crankshaft height and a larger engine base plate. there is a very simple fix you just have too get belts and two belt cover riser brackets for an ariens 924071 st1136
02450751 rh riser
02450151 lh riser
07206600 traction belt
07208600 auger belt

i used these parts when i did the repower on my 924044 st1032 and after drilling the new holes everything worked out perfectly. unfortunately this is what you will have to do unless you dont mind installing a used engine. depending on where you are located i do happen to have a few used tecumseh engines but honestly i would do a valve job before putting any into service

 

I thought I recall someone fabricated an engine mounting plate for this exact reason and had them for sale.

 

Exhaust valve lash adjustment

 

This should be the plate to fit your needs.

shaw to rescue as always

side note i have a couple 10 hp tec motors

 

OP should list his location. Might be a Forum member Local with an engine.

 

@Shaw,

Yeah, I knew I saw that somewhere, thanks for posting it ... maybe that could be added to a sticky to a new section called "Tools, Tips, and Tricks" ....

 

If it was me, i would just locate a good used 10hp Tecumseh, they are out their in abundance. They can be found fairly easily being sold on craigslist, Ebay, etc. You can find them by themselves or on machines cheap! I just picked up a perfect running used 8hp Tecumseh with the electric starter at the small engine show I went to over the weekend for $50 bucks. I bought it, so I could swap a 10hp I have on a Craftsman I'm going to sell onto my ariens ST824 that is mine for the little boost in power. Also IMO, nothing beats those flathead Tecumseh Snowking engines anyway. 10hp, 358cc. A lot of the engines now ate are underrated in comparison. If it was me, I would find another good 10hp Tecumseh for a bargain. The Ariens usually uses a 1" diameter shaft, so just make sure you get one thst has the 1" shaft. Otherwise you'll need to get a shaft adapter. Besides that the Predator 212 is a great replacement. You will need a 3/4 to 1" shaft adapter. Their only rated as 212cc, but, they run at 4000-4100 rpm no problem, so their about just as powerful. For the price for a brand new engine, those are also a great option.

 

Anyone use one of those plates? Any idea if it would work with a lct414?

 

I was wondering the same thing. I know Husqvarna has an engine mounting plate that bolts to the frame for their machines when they switched from Tecumseh to LCT. The plate above might be easier.

 

Can't speak about the plate, but I can say that model snowblower + that model engine are a match made in heaven - I put that same engine on my ST1032. The LCT 414 (and probably other similar engines) has a balance shaft in it so among other improvements, it has way less vibration than the original engine... and the engine has all the torque you could ever want.

 

Where are you from, Johnny?

 

I'm just north of Boston in Rowley, MA.

 

Im in MA and always see Tecumseh engines for sale on CL, either separate or on machines. I have the HSK70 and love it, if anything happened to it I would try to rebuild it, within reason. But then again I find working on small engines fun. I recently picked up a pair of craftsman pressure washers with Briggs cr950 engines that were "parts only" for $25 each at Lowes, got them both running perfectly and sold one for $140 and keeping the other. It looks like the engine will fit my 1971 Sno Thro also. I was also looking around online for Tecumseh replacement engines and Briggs came up alot as being a good swap.

 

Stick a 420 Predator on the big blower, you'll be glad you did. I know I am happy with my 420cc engine swap.
