Repower 536.909800 from 8hp tec to 212cc predator

So my 8hp tecumseh threw a rod. Has anyone put a 212cc on the old eager 1 3 stage drift buster by craftsman? Model number 536.909800. Just a quick look I am going to have to either modify the chute adjustment arm or raise the motor and get different belts. Also in refernce to the original holes from the tecumseh I have to relocate the predator to the front of the tractor towards the belt pulleys. I give the move up credit to the sump pan on the old motor being much larger vs the predator.

Any advice or guidance or pictures would be great

Thanks!!

I did an HM80 to 212cc Predator change on my Ariens and everything lined right up. Mine had the lower chute rod with universal joints so that was no issue. I used the same mounting bolts as well I think. I did need to get new pulleys as the old was a 1" crank and the new was a 3/4" crank.

On an old Toro 3521 I put one of the older Greyhounds on and I used a 2x4 as a spacer between the handles and the chute crank mount to move it out a bit.

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

Remotoring

I can't say I've seen anyone remotoring that model with anything other than another Tecumseh but no reason it shouldn't work. You've noted the likely issues on the chute or maybe the control cables.

I have to do something with the chute rod. Move it out or move the motor up. Maybe even make a new bracket that is shorter. To bad the engine jug isn't on the other side. Other than that it has to moved ask the way up in the tractor and new holes drilled

If you move the motor forward I don't see the belt cover fitting on anymore. Same goes for raising the motor. This would be a big deal to me.

How wide is your machine ??
I have the 10hp 32"s and I know the 212cc predator would be disappointing. From what I've read of others who did put the predator on their machines I haven't seen anyone with complaints. Most are very happy with the re-power.
You need a belt cover but if it's a matter of going with a new cheap predator and fabricating something or spending as much or more $$$ for a worn Tecumseh I'd go with a fabricated cover.

I'm thinking my game plan is to move the motor as far forward in the mounting plate, the modify the brackets for the chute rod as needed. This way I can stick with my new belts and I won't have to play the guessing game on what belts works where and what size. Only thing is I may have to move the dual pulley further out on the shaft than I'd like to get it inline with the lower pulleys. Rough calcs based on the predator blue prints and some diagrams I found on the hm80 I need to move the predator forward about 3.5" I can account for 2.75 on the mounting plate, the rest will have to be in sliding the pulley out on the shaft unfortunately. I came up with 3.5" from the hm80.sump depth of 2.5" and a difference in shaft lengths i think it was 2.43 on the hm80 to 1.79 on the predator.

Thoughts?

1.79 is the length of the keyway on the predator. The entire shaft is also 2.43
