Toro 521 Predator conversion

New member here. Just got a 60363 Predator from the local HF store, so I'll be doing the conversion. The original Tecumseh is OK, but I need to return my new Chinese carb because it has a defective float and the ground terminal broke off the magneto. Anybody need a decent HSK50 Tecumseh?

Put the engine in yesterday, and it's pretty much bolt-in as people say. Two trips to the hardware store as expected, and it's good to go.
Did some other adjustments and maintenance too. The Predator 60363 started on the second pull and runs nice.
Took most of Saturday, but I didn't hurry.
Piece of steel tubing and 3" bolt to move chute control out.
Carb linkage snow shield make out of a scrap of sheetmetal.
Tabs to fit in muffler cover, Velcro on air filter housing to hold it in place.
Dummied it out of a beer carton and then traced it onto the sheet metal.


Home made skid shoes. 2x2 angle iron cut, drilled, hammered.


Original key switch wires rerouted down right side. They barely reach. Tied into the factory on/off switch.
Cut the ring terminal off and soldered one wire into the male barrel connector. Other goes to ground as shown.
Tapped oil drain for 1/8NPT. 2" nipple installed with LokTite blue, overpriced brass cap from Ace Hardware.


2" W rubber left over from and old POS single stage snowblower rebuild.
Put in with 1/4" carriage bolts and nyloks. I assume putting the rubber on the "snow side" of the auger is correct??
Used my cutoff wheel the grind and extra tooth on each end of the chute ring gear to give it extra turning range.

Excellent work. Looks great. Thanks for the pictures and details.

I almost went down your route with my 521. However, a forum member that lives a few towns over from me was nice enough to sell me his used HS50. He'd done his own HF engine conversion on his blower.

I expect that I'll eventually need to go down the HF path at some point.

Looks good!

I have my old 521 in the back of the house, with a need for a new belt, new carb(?) or new motor.

I may CL the machine as-is to see if there is local interest. Too many other things to do...

Nice.
That oughta take whatever you can stuff in the bucket at jogging speed.
Where did you find the oil drain extension? After I threw a predator on mine on this week I realized what a mess it's going to make changing oil. That is a metric thread is it not?

Thanks for the compliments!
This conversion will ensure that we get NO snow for the next few weeks.
$99 coupon on Predator engines til the end of January!

The Predator oil plug appears to be a metric flange bolt with an aluminum washer. The hole is about the correct size for a 1/8NPT tap.
I coated the tap with wheel bearing grease to catch the chips and ran the tap in most, but not all the way.
The 1/8" NPT x 2" long pipe nipple and brass cap are from Ace Hardware, but Home Depot should have it too.
The pipe nipple is installed with LokTite so it will stay put when I remove the cap. You can probably use a dab of epoxy instead.
The pipe just reaches the edge of the frame. At oil change time I'll pull the right wheel and shove a small funnel in there to keep from making a mess.

Nice job on the swap! My blower is quite similar to yours, and I may need to do this some day as well (fingers crossed, not for awhile)...no hint of snow here yet either!
