Cool 91' Toro Powershift 824/Predator 301cc Repower finally done

I will start by thanking other forum members who shared the repowers in the past with the Predator 212cc. I did one of those for a friend and posted nothing as everyone has seen them, but was thankful for having this resource for info that was here already on those! Now..this is a different beast, a 301cc (shrouded and rejetted) on a Powershift

Here it is finally, after a few weekends of getting it sorted. I didn't work on it at all during the work weeks mostly due to the cold weather and not wanting to heat my garage for only an hour here and there I waited for weekends.

Started this on New years day when I drove and picked up the engine. Took the sale price plus the coupon so in the end it ran $191 and change. I knew I would also need belts, so tractor supply was the next stop a day later. The old Tecumseh 8hp still starts well and I will sell it on CL, it didn't seem to have the grunt I wanted, was loud like all the older L-heads, and of course vibrated so much the chute would shudder . Ran good though, I just wanted a project other than woodworking for a change and had "the upgrade bug" after just having done a 212 cc Predator repower for a friend that had a junk motor (was a Simplicity 860) and was impressed by that 212cc too. Maybe the fact that my neighbor has a brand new Toro Powermax with a modern, quieter 250cc Briggs (chinese made as well) that just sounds less harsh than the Lhead had a lot to do with it. I like to enjoy the quieter power too!

The area I live in is tough sometimes too,I just feel like the heavy wet snow we get around here on the coast sometimes would be so much MORE fun with power-to-spare, especially since the impeller kit proved to really throw the slop even though I only have had chance to test it with a four inch slushy storm. That slush flew right out but only a few feet. At least no clogs

Onward: So, I got the new block mounted up after redrilling a couple new hole locations, squared, new bolts,washers, nuts and belts fitted, adjusted, then removed the belts and did the three hour break-in mostly idling but some throttle ups here and there for short spurts, over a few days an hour here and there and then replaced the belts and tried the gears and auger. I notice even at idle I can squeeze both auger and traction and the engine is strong, holds on good! Had to get 3 inch longer belts and adjust my cable quite a bit due to the extra 1 inch in height of the shaft center, and slight off-center measurement. I tried 2 inch longer (you would think!) but a slight bit too short. It did also require extending the height of the belt guard about 3/4 inch.

First impression, Impressed I'll say one thing right off the bat, it's torquey! I put the trans in fourth and left it at idle speed and it pulls like a husky dog, I was trying to hold it back with the bucket just tipped off the ground..no sign of bogging or studdering even at idle speed of around 1920rpm. I thinks it's the "grunt" I was hoping for.

Snow shrouds : After the major stuff was sorted, I decided to make front and top shrouds for keeping the snow out of the governor and linkages.. had some light galvanized metal in the shop and semi-gloss stove paint so started to work on trying to remember some sheet metal skill I used to have 30 years ago when I was in high school. They turned out OK, although the top one would have been better one piece, I didn't feel like buying more metal just using what I had on hand so I riveted two pieces. Good enough it works.

Jetting details : I ran it no-load while 28 degrees and it ran uneven, so removed the main jet, figured out what size it was stock (.038) by carefully using the back end of the drill pit as a measure pin so decided small steps are best and went to .039, which worked fine. Smooth running now. I then opened the idle jet one notch as well, to help with cold starts. I forget the numbers but same method used. Tried it at 19 degrees and it seems to have been enough of a change still starts,idles and throttles well, holds full throttle (only held it there about 8-10 seconds, since engine still new) without surging so I'll leave it there unless I have surging under load. If that happens I'll ream the main jet only just a tiny bit. There is more volume difference in one thou (.001) at .039 than there is at .028 like on the 212 motor, it's a math equation I wont get into here but it's more.

Last but not least I added a Drainzit (12mm1.5) oil change hose on one side, and because of the cast iron bore I have ordered a magnetic drain plug for the drain port on the other side just because I stumbled upon one online for 5 and change.

I put this up for all to check out because I have enjoyed the other forum members having shared the repowers with the 212cc and they educated me so I could help out my friend.. and having chosen the 301cc not many have used yet, thought it might help someone out there. The Toro Powershift (model 38540) I have had the Tecumseh with 1" shaft and that's the main reason I went with the bigger motor, simply was easier, and even though it was a bit more money I will enjoy a bit more power (grunt grunt ) and toss that wet snow even further

So I'll end with a half dozen pictures and a thank you to the members that shared the 212cc repower info.. that got my upgrade wheels a' turnin'.

Cheers! BRING ON THE SNOW NOW ! Hope February brings a different weather pattern !!

Edit: I got my wish, February brought SNOW ! Now somebody turn it off ;-)

ALSO: chute liner removed, too thin plastic was punctured by ice chunk. I will be installing a strip of Stainless on the back vertical of the chute at some point. For now, Ski Wax !!

.Edit : Jets are now at .039+ main jet, and .0225+ for pilot jet and I like the wats it's running ;-)

Congrats and very nice work indeed. I was in the same boat when I was building my Honda. We get a lot of the EOD pile ups, thanks to the town plow guy, so played it safe and upgraded to the 9hp GX270 instead of the 6hp GX160, no replacement for displacement as they say

Nice Job, I am sure it will work well for you. I like your chute liner

I repowered my 1983 large frame Cub Cadet with a Greyhound 340cc (11hp)with electric start about 3 years ago and I couldn't be happier. I put a 1/2" larger impeller pulley on it and impeller kit (14"impeller) and at full throttle it is a monster. Most of the time i only need to run it at 1/2 throttle or less with snow up to 8 inches.

nice work, almost looks like it came from toro that way. even thow my powershift is running I am thinking to the future and what motor to replace the 8hp Tecumseh with. I've looked at the 301 predator but I need electric start

I would love to see the 420cc HF motor with electric start on a powerShift! man that would be awesome

Looks like it came from the factory, very nice fabrication on the snow guard and chute liner Pathfinder. Funny, now you don't have to look for a path, you can make your own anywhere you want.

Toro 8/24 (38080) 1989
Toro 421-QZE (38585) 2008 (Gone)
Toro 721-QZR (38741) 2015 (Hemi Predator Power)

Experience is something you don't get until just after you need it.
