Troy-Bilt 8/24 re-power

I picked up a an older Troy-Bilt 8hp 24Ē model 42010. Previous owner said it has very low hours and it shows. Very clean machine for its age. I posted a pic in another thread and thanks to this forum, you guys noticed it actually had an older 7hp Tecumseh engine.

The engine had trouble starting but got i got it going eventually. It runs a bit rough and noticed it was leaking oil. Since the machine is in great shape and built like a tank, i want to re-power it.

I was looking for an 8hp engine but got a great deal on a Predator 420cc. I know this is a lot of power for a 24Ē blower but itís pretty much in the same category as my Ariens SHO 24Ē 369cc which is a beast. That machine is used at my commercial property.

Comparing the specs of the current Tecumseh engine thats on there now the the shaft height on the Tec is 4.1Ē (if iím correct) from the mounting plate to the shaft vs. 5.26Ē on the Predator. What size belts will i need?? I tried to look up the current belt size so i would have some idea but had no luck. Any ideas? Thanks!

i could be wrong but i feel like a 420cc 13hp on a machine that size is overkill. i would maybe shop around for a 250-300cc.

as far as belts go you almost need to swap the new engine on so get an idea what size you need.

Even the 301cc would barely bog down with a full bucket of snow.

420cc is way to big for its current gearing. I say use the 420 but bump the auger drive pulley by an inch minimum and install an impeller seal kit. It’ll be a monster.

What is the OD on the auger pulley portion of that pulley? You could probably go up to 3.25" or 3.5" comfortably.

(On my GX390-equpped 9240404, I'm running a stock Ariens 924 series dual pulley which is 2.75" for the auger belt and 2.5" for the drive belt. I'm planning to go up to 3.25" for the auger belt)

Once you have the engine installed, you'd probably need to use a piece of string to determine the needed belt size.

Troy-Bilt 8/24 re-power

Thanks for the info guys. This is my first re-power so iím sure iíll have more questions. Iím going to remove the old engine this weekend and bolt up the predator for measurements.

Iíll measure the pulleys that are on there now.

You might not have to adjust to much... they put a Riser mounting plate under that Tec...So if you remove the TEC. engine and the riser plate and just mount predator you might be close with the belts!!!! So before you remove the tec try to get some type of measurement from center of the engine PTO shaft to where bottom of riser meets body of TB(base). Then when you bolt up the predator with out riser....you might be close in belt measurement. Just thinking...???


I always thought Tec's(hence need for riser on TB) were 4.25 and Briggs were 5.25.....PTO height. Your belts might already be adjusted to 5.25height due to riser so Predator might fit just right without riser. Ok I am Ramblin' at 12:30am...Let us know how you make out!


Not sure If your engine sheave is 3/4 or 1" but that might be an issue???

I donít think there is a riser plate on mine. I donít see one. I didnít think i would have to change so much lol.

The engine sheave is 1Ē on both the Tec and the Predator.

I've never seen a riser on any Bolens 24" snowblower.
