This is a Genuine OEM replacement part used on a variety of Lawn Mowers. This item is made out of Metal and it is Sold Individually. If either the ball bearing or the bearing retainer wear out this will cause the wheels have trouble turning. Ball bearings are used to reduce friction between rotating parts. The balls or rollers take the load and spin, distributing the weight evenly while the minimal contact area of the ball reduces friction. This reduces wear on the tool and allows it to run smoothly. Bearings experience constant wear when the tool is in operation from pressure, heat, vibration and friction. Because of this, many Bearings need periodic maintenance or replacement.

Easy Repair
Have a 10 year old Toro. Great mower, but the self-propelled transmission wore out. Love your website with the schematics and numbered parts. Found everything to rebuild the rear axle - transmission, bearings and sleeves and the mower is like new again. Liked that everything was in-stock!!

I'm still working on this repair. Replacing the ball bearing and bearing retainer was simple. The biggest problem is removing the retaining ring clip to access bearing retainer. I bought a special tool to expand it. But it doesn't expand it wide enough and I really had to wrestle with it. Once I got it off, the bigger challenge was putting the new one back on after replacing the ball bearing and bearing retainer. The pliers don't expand it enough to get it back on. I'm going to Northern tool to look for a better tool. The one I bought at an auto parts store simply doesn't open wide enough.

Watched video on utube. Repair was not extremely difficult. They steps to change out transmission are to long for me to get into. Replaced ball bearing while I had it apart. Old transmission as well as the replacement have no way to check or add oil. If I had a way to add oil , in my opinion could have saved old transmission.

You have to remove the drive gear and adjustment plate to get to the retainer bushing. Because it is probably rusted on, you will need to use a very large wrench or a vise and hammer if you do not have the right size wrench. After you get it part reassembly is very easy.
