Toro impeller bushing modification

Hello All.....

I know I'm an Ariens guy...... But.....

I was servicing a toro 10/28 machine for a friend, came across the old worn out impeller bushing issue that all owners have or will address on thier toro. I didnt find a thread here about replacing the OE design with a bearing, so I decided to make one up and post it here for others to see the process.

Here they are side by side...


Used an Ariens axle bearing... ( Also on newer Ariens impellers )


Used an Ariens impeller bearing flange setup, can be found on any 24" machine...


Originally I was going to put spacers in between the flanges to keep from crushing the flange as bearing didn't fit into toro bucket hole, and then bolt on the bucket as toro one was. Didn't like that setup, so i decided to open up the bucket hole and install bearing assembly like an Ariens.

Had to remove only 80 thousands to make bearing fit nice and snug ...



Flange plate holes were slightly different than OE ones, I decided to rat tail file them to fit rather than drill three new holes...


Flange plate lined up nicely....


Completed installation.....



Hope this write up helps others with thier machines, and pictures are clear as to what was done.
If there are any questions please ask and I'll do my best to answer.

How are you dealing with the endplay?

You know if you got the bearing and flanges from and old school TORO it would of bolted right up in there. and you would not have had to waste time Dicking around with that 1. And that is All the more I am saying on THAT 1.!!!!!!!!!!!!!!!

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

To Mr powershift93.....

It's sad when I see people like yourself who would rather have just negative remarks and comments instead of helping others. If you had this knowledge of using older Toro parts to address this issue with their bushing why didn't you post up a thread of your findings and help others with this great modification / improvement ??
If you did post up your findings to help members here and my search missed it I apologize and please disregard my comments.

I'm not one to bash or start BS, but I took what you said Very personally. Since the day I found and joined this forum I have done nothing but help others, either by posting pictures or offering suggestions that I've learned in over 35 years in the trades. Several members have come by my house and we repaired their machines, no charge, all I asked for was a handshake and a thank you with the possibility of a pay it forward favor to another person in need.

Now that I'm done with my rant, I apologize if I've offended anybody. Had to get that off my chest.

Where do you expect to have end play ??
The id of bearing was roughly .881, it slid perfectly on to the impeller shaft and od was exact size of flange plate, bearing had no free play in the bucket opening. The pulley slides on to the impeller shaft where it was from the factory.
I might be missing what you are calling end play, if I am please give me more details so I can better understand what your asking. I still have machine here, I can go check to see what you are asking about.

in a simple fix,that stock bushing bearing. where that stud is threaded in, drill it out all the way though, tape 1/4x 24 and install a grease fitting, the zerk works like the stud to keep the bushing from spinning in the clamp housing, a few shot of grease each season ends the toro seizing on the shaft problem i personally suffered from many times.
this also works on both auger end bearings and axle legs

also on both of my powershifts i had the leg/axle bearings lock up on the axle.spin in the leg, i reinstalled the bearing in the legs with the aid of 2 small sheet metal screws and a angled zerk no more axle problems

I don't think he's being negative its just the way his typing and verbiage comes across

He posted something helpful about this topic and others on my rebuild thread. Unfortunately I read it after the job was done.

The endplay is from the gearbox. On the stock bearing one side has a flat spot that needs to face out toward the pulley. They put washer between the pulley and bearing most of the washers are missing or broken so I always use a new one. Before you tighten the pulley setscrews rotate the augers back and forth you will see the impeller shaft move in and out. Hold the impeller shaft toward the rear to take the play out then a light tap on the pulley to make sure its down and tighten the set screws. Than spin the pulley to make sure it rotates good. If done this way I have never had a problem with the stock setup. Early failures are from improper install of the bearing, impeller fins bent, or bad belt tension.

Thanks for the information, I'll see how worn the next one is I come across and install zerk fitting. I love the idea of a greasable bushing over a bearing. To be honest I never thought of adding one, great idea. This was only my 2nd Toro as I tend to stay with ariens.

This is why snowblower forum site is awesome, sharing & swapping ideas to help others doing their repairs, and perpetuating the trade.
