I picked up my new idler pulley today and spoke with the parts guy about the pulley problem, He said he has not seen or heard of my problem before. He agrees a greasable bearing would correct the problem but could not find one to fit my mower deck. I think I will start checking with auto stores and see if I can find one. Thanks for the help with this problem.
I am not sure a greaseable bearing will fix this. Sure it seems sensible to suggest if it had grease it would not fail.
But, why is it failing? If it is failing because the bearing is not able to take the load being applied on it, then all the grease in the world will not save it.
If it is failing because of lack of grease, where is the grease that is put inside it when it is made going? A sealed bearing will run a long time before wearing out, because the grease is sealed inside.
If it is failing because the grease was washed out of the bearing by use of the WD40, the solution is obvious. I would assume though, the WD40 was being used because at least one bearing had failed, without having the WD40 put inside.
Is it failing because the bearings are Chinese junk, and defective? Then possibly the solution is to replace them with nonjunk.
Can the bearings be removed, (pressed out), of one of the old pulleys? and can they be dissembled to do a postmortem?
If it is removable, there is usually a number on them that you can use to buy a replacement bearing.
If they are not removable, do you have a surplus store in your area or a mower shop that has a lot of stuff like this, perhaps you could find an alternate replacement?
A larger bearing would likely be a solution if you can find such a pulley and modify your deck to use it.

Let us know if you find a heavier duty, greaseable alternative. Thanks

I can not do anything with the old pulley as it disentergrates when it blows.
I looked at the new pulley it does not say where it is made.
As for the WD 40 I was unaware of it being able to clean out the grease, so no more WD 40 on anything like bearings. I will look around for a different type of pulley and if I do find one I will post this.
The issue with the WD 40 may answer problems that I have had in the past with other things. I thank all of you for educating me to the facts of WD 40.
