Hydro fan Toro 522xi

Recommended Posts

When installing my hitch last night I noticed the fan for the hydro just spins on the shaft. How is it supposed to attach?

Found this in the service manual. Looks like the fan is on the input shaft before the yoke is installed.

A look at the fan it appears to have a key way slot at the top of the bore in the photo.

Well, I finally got around to looking at this tonight.

 

What a pain in the A$$. You have to remove the driveshaft(at least an hour process)

 

Then I had to remove that 1/4" bolt that ("A" in the pic Gwest_ca  showed)

Then loosen 2 set screws and pry the flange off the transmission input shaft. 

 

The fan has a slot for the woodruff key but it doesn't actually engage to it, it is on further down the shaft.

I put a 3/16" thick 5/8" washer on, then the fan, then the flange and then the 1/4" bolt pinches it tight.

 

then another hour putting the driveshaft back in.

 

I'll have to see in the am if it works
