I have a qa42a and I'm putting on a new 5/8 pulley for my Cub Cadet 782. I've been using it with the mis-matched pulley and going through belts like crazy. So, I decided to get the new pulley on there and see how it works when there is a little less belt slippage. While taking the old pulley off, I noticed the bearing behind the pulley was completely gone. There was nothing there.
Here is the gearbox with the arrow pointing at where the bearing should be . . .

. . . and here's a close up of where the bearing should be . . . .

I've seen diagrams of what goes in there, a bearing and a seal and a retaining ring, but I can't seem to find part numbers or at least enough to ensure me that I'd be ordering the right thing. Is this something CCSpecialties would have? I've been on the sight but couldn't quite determine what parts are needed. Any help is appreciated. Thanks

It appears parts are discontinued... Which stinks mooch-O alottas. I'd imagine parts are generic and can be bought at a decent hardware store though...

But wait, there's more... It appears the JD 49 gearbox could possibly be identical and parts for them are still available.

(You got me interested since I have 2 of the snowthrowers myself and wanted to be sure I can still get parts. I read on another site about the JD being identical but I'm not absolutely certain myself)

There's nothing I don't have for gearboxes.

Nothing is NLA for gearboxes, other than new gears, which I also carry.

Thanks for the response @digger, I'll get an order in. On of the shafts has a wobbling woodruff key. I was going to improvise an improvement for that before putting it back together.

Can anyone more knowledgable than me recommend the kind of gear box lube? I was contemplating sticking a grease zerk on the gearbox, but I can't seem to find the 1/2 90 weight 1/2 grease that has been recommended in one tube. I was thinking of lubing it with this stuff. Any thoughts?

@digger I believe the bearings are mis-labeled. The bearing PN/IH-475628-R92 designated as "INNER" is actually the outer bearing, because it is the sealed bearing. The other one sits inside the gear box, and and therefore protected. I need an outer bearing.
