I have a Snapper 21" walk behind mower (7800424-RP217020BDV) with the disc drive.

The disc drive bearing is bad.

I ordered a part from amazon with the same part number, at least it cross referenced. Tried it, but the bearing slides right out of the thrust plate. Nothing holds that bearing to the thrust plate

The part from amazon fits, but obviously won't work.

I should have ordered from the Snapper website. But my fear is it will be the same bearing.

The old bearing when I removed it popped right off. I think the bearing had a pressed collar of some sort, but the bearing was in such bad shape I couldn't really tell.

I'm ready to order from Snapper Parts; has anyone done this repair before? Does the replacement part from snapper have something to old the bearing to the thrust plate?

Thanks in advance.

Job complete.

Using #10-32x.75 screws with a appropriate washer and nylock nut, I was able to secure the new bearing to the thrust plate.

See pictures.

After the repair I mowed and noticed the machine is alot quieter. The bad bearing makes quite a racket! I did notice quite a bit of vibration at the new bearing, so I wonder how long that bearing will last.

Hope this helps someone down the road .;)

order parts from a real repair shop and you will get the correct parts. don't use amazon for small specialized parts such as what you needed
