Ariens 8 H.P. To A Predator?

I have an older Ariens model 910018, with a Tec. 8 H.P. model HM80-155020. This engine is getting tired, and burning oil. Been thinking of a Predator engine swap. The Tec. I have now is a 1" shaft. From what I have read in these forums, the Predator 212 cc has a 3/4" shaft, while the 301 cc has a 1" shaft. Has anyone done a similar swap, and what are your recommendations? Sounds like either way, I will have to change pulleys, or belts, or both.

I have put the 212cc Predator on 2 924xxx series machines. One was a 7HP and one was an 8HP. Both work well now. You are correct that the 212cc is a 3/4" shaft while the HM80 is a 1" shaft. You will need to either spend another $20 for the sleeve or spend about $10 each for 2 new pulleys.

Actually, the 10,000 models were single belt drive so you would only need 1 pulley.

I have seen pulleys locally at Tractor Supply Company and Rural Kind where I live. I have also ordered them from MFGSupply.com and have seen others order them from EBay.

Please direct all snow blower questions to the forums and not to me with PMs.

I went from hmsk10 to hmsk 8, so from 353cc to 318cc. If you go from 318cc to 212cc you might be underpowering a bit too much? Just saying because I noticed a 35cc drop.

i have one of those 910018 blowers and i put a predator on it no problem, i didnt have the original engine so i thought it came with a 3/4 pulley which i found in my parts pile. when i went to order parts i found out the original engine was an 8hp which would have came with a 3/4 inch shaft. all you would have to do to put the predator on it is to get a 3/4 inch pulley at tsc and cut off the chute rotation bracket thing(the engine shroud wont clear it)

good chance the tech never made its advertised 8 hp to begin with, so the 212cc engine should perform well at 6.5 hp. ( is the 212 rated for 9.5 ft/lbs , same as the 208's ?..just curious)

I replaced a HM80 on my 924040 (8hp+big wheels+solid axle) with a Predator 212cc over the summer (#9 on my signature below). I'm using the one of the eBay crank sleeves to reuse the old 1" crank pulley.

I am thinking the 301cc would be more 'plug 'n play' since it is the 1" shaft. The rated HP is the same as the Tec, but I would imagine the results will be better with 301cc's

I replaced a 318 CC Briggs and Stratton 8 horsepower with the 212 CC Predator and the Predator is definitely up to the task on the 26 inch snow blower. The Predator 212cc engine will easily replace any 8 horsepower Tecumseh or Briggs And the 301 CC Predator will replace a 10 horsepower flathead really easy as well.

no it wont be unless you want to drill new holes. the 212cc is the same except for the shaft size. a pulley for 2.24 will fix that problem
