I need details on a part (see pic attached). It's for the craftsman snow blower 536.886122 and is the bracket for the auger belt tensioner. It's damaged and I need to find a replacement.

Thanks for the help

Hello AndrewJ,

How is the bracket damaged??

Is the snubber pulley bearing shot and is that the real issue????

The tensioner bracket was gouged by the pulley when the belt slipped off and cut deep into the part of the bracket that holds the belt close to the pulley when tension is removed. Sparks were flying. It happened very quickly. The edges of the auger pulley are also damaged.
Will post pics when I have a chance to get at it.

Hello Andrew,

No worries. You have a little rubbing wear on the idler arm thats all so there are no worries there.

If the bolt hole bore was damaged and the bolt shoulder is no longer tight then I would add some weld and then drill it back out to the bore diameter of the shoulder bolt that carries the snubber pulley.

You will want to find a new snubber pulley as the bearing is shot just so you have a new pulley and bearing to mount on the tensioner arm and they all have common sizes so you should have no issues finding a new one.

If I did anything I would sand it down with rough and then fine emery paper and paint it with a couple coats of white rustoleum paint before you mount it back on the snow blower.

Change the oil, change the belts, check the rubber drive tire disc before you start the season and you should be all set. you may need a new drive tire as they will break down over time and the rubber degrades from exposure to ozone.

It may be well worth your time to install an impeller kit on your snow mule to throw the white stuff
even further away to get rid of it.
fluid film works wonders to lube up the cross auger housing, chute and spout and you will have a ready to run snow blower.

Hi Leonz,

Thanks for all the great advice.

Here are the damaged parts. I finished grinding /sanding them smooth, coated with rust protection paint and installed.
Hopefully we won't have any trouble this winter.

Now in the process of cleaning the carb. Looking for the appropriate gasket replacement kit.

Hello Andrew,


The gouge on the arm is nothing to worry about at all. I would just purchase an identical snubber pulley with the sealed bearing and go from there as it rotates a lot faster and covers more miles than any of the other pulleys or the impeller.

Andrew if the bearing and pulley were OK it would have never wobbled and gouged the arm that is why I am telling you to replace the pulley with a new sealed bearing snubber pulley. Other than needing the new snubber pulley it looks fine.

I have had the same issues with the JUNK JD snowblower I have and I have replaced pulleys and then found out that the bloody thing was shipped incomplete from RAD in Canada this year from a service bulletin that I received from another dealer.

Leonz,
Thanks for the advice. Makes perfect sense.
What is your recommendation regarding where to pick up a new sealed bearing snubber pulley? Are there reputable suppliers on line?

BTW, New belts are installed, oil changed, required parts greased. In the process of rebuilding the carb.
Here she is all buttoned up. Not bad for a 21 year old machine, don't you think.

Hello Andrew,

Your snow mule looks very nice and ready to work. with my past experience using my JD junk I would pour windshield washer fluid in the tires for added ballast-The LAA 115 I have would not even dig in to snow pack or piles unless I had a running start-I had chains and 82 pounds of suitcase weights and my butt in the seat and I still needed the 8 gallons of windshield washer fluid. The LA115 I have has only has 2.5 horsepower per axle half at any time.

Andrew about the replacement snubber pulley, I would just check with any local power equipment shop that handles and sells snow blowers as the snubber pulley is a common part of the snow blowers-if that does not work Mcmaster Carr or KAMAN Industrial is another pair of options but I think you will be able to find one locally or nearby with few issues.

About your carburator-you should look at buying new larger fuel jets if they are available to give you more power when dealing with the END OF DRIVEWAY MONSTER. We have talked quite a bit about installing larger jets in the snow engines on the forum.


Have you pulled the bottom cover off to look at The drive tire??? if you have not put fuel in the tank yet I would put the snow blower on its nose and unbolt the bottom cover and look at the drive tire to see what it looks like.

If you have rubber dust on the cover when you take the cover off you should replace the drive tire as the rubber has started to crumble.

Yes, had her completely apart and drive box looks good. All rust is now removed from every part and new coat of rust preventive paint applied. She looks brand new now and ready for another season. Will look into larger jets for the carb. Thanks for all the advice.

Is the rubber seal missing on the auger bearing? It looks like it to me. See attached picture
Good point. I didn't see any seal when dismantling the unit. I reinstalled as it was. (I dismantled on my work bench so I would have seen a rubber seal if it fell off). The auger pulley attached directly in that shaft with the two locking bolts towards the front on the machine.
Do you have photos of that rubber seal?
