Impeller bearing replacement and kit install

Hello all,
Toro 1128OXE new fall 2005, 83 hours on the meter. I do all my own maintenance on this machine.

The impeller bearing was shot as there was alot of play in the shaft and noise from the impeller scraping on the housing. I figured that if I opened it up to replace the bearing I would also install a kit in it while I was in there.


There are many ways the machine can be opened up for access but here is the methods I used (note some pictures may be slightly out of sequence):

I started by removing the chute. Remove chute stick control cover and slide back


Mark location of cable then loosen the pinch bolt and remove the cable



Im not a tool hog but my old ratcheting box wrenches came in handy here




Once disconnected the chute just lifts off

Unbolt the chute control rod from the control


Remove the pulley cover, pulley/belt guard, and disconnect the impeller/auger drive belt from the engine pulley


Disconnect the impeller pulley brake retract spring (I should have just removed the entire brake assembly here as it needed to come out later)


Remove the lower side cover


There are three large bolts on either side that hold the impeller/auger housing to the rest of the frame. The middle ones on both sides go into slotted holes and dont need to be completely removed. Again, stainless bolts intalled 10 years ago came right out (ratcheting box wrenches help here too)




The back half of the machine will not stay upright on its own so I just rested it against my wheel barrow

To access the impeller bearing the impeller/auger drive pulley must be removed. I had read some real horror stories about removing these things.



Start by loosening the two set screws. Not much working or sight room.


I dont have any 8 point sockets so I had to improvise using a method I saw on a youtube video. Yes thats a 5/16 open end wrench in a vice grip



With the sets screws loosened the pulley would not budge (no big surprise) so I improvised again using some recommendations I found on the internet - use a puller which required two holes to be drilled in the pulley


I did alot of automotive engine rebuilding in my younger days but hadnt used this thing in years


The shaft protector on my puller was too big for the shaft so I just used a small socket


And the dam thing came right off - no theatrics or even any cussing

At this point I decided to remove the impeller housing upper cover. Stainless bolts installed 10 years ago came right off




Housing upper cover

First look in with cover removed

thats kind of disappointing that the bearing only lasted 83 hours, considering both of my ariens are still using what i assume to be the original bearings, and they are 40+ years old. does this toro using a bearing or does this toro use a bearing or a bushing?

So, Toro had its impeller area plastic cover "anti clogging" system back in 2005...? I thought it was something much newer.

The three impeller bearing retaining bolts are carriage head bolts and are buried behind the impeller. These bolts/nuts have never been replaced


Since I am going to replace them I needed to move the impeller out of the way. A broken record here - but the stainless bolts I previously installed for the impeller shear bolts came right out allowing the impeller to slide forward on the shaft allowing ample room to remove the bearing retaining bolts


The shaft woodruff key and thrust washer must be removed


The extent of the wear on the bearing is visible even before I removed the bearing


All bearing retaining bolts removed


And this is what came out. What a mess. Its hard to believe but the unit was actually working and throwing snow the last time I used it





Thankfully the shaft where the bearing rides was in very good shape

You do know that a 12 pt socket works for taking off those square bolts. as long as the socket set. is not bought off a truck on the side of the road. that also sells dogs playing poker wall rugs. along with a few other things that I will not get into here.

Long LIVE THE POWERSHIFT!! MAY IT NEVER RUST IN PEACE!!

That is the same bearing set up that the POWERSHIFTS run. I still have to look into a sealed roller bearing replacement. the next time I change 1 of those out. but then again that might just be sometime in the next century.
