I pulled off the pulley to check it and wondered if there was a way to lube it. I got the right angle pick under the edge of the seal and it popped off. Then I used my "grease applicator" and filled it with grease and popped the seal back on.

 

very clever. i didn't know it was just a ball bearing.

 

It wasn't making any noise before I checked it, so it's a good idea to check it before it makes noise.

 

Of course it's a ball bearing but did you use a hi-speed grease?

 

Uh, maybe. What is a high speed grease?

 

Can you get to the seal keeping it installed? If so, that's easy to keep lubricated.

Sealed bearing should not be lubed. Disturbing the seal only compromises it and encourages it to fail. If (when) the pulley bearing should go bad simply replace it.

 

Hi Speed grease is formulated for work in Hi-Speed bearings and usually has a higher than normal heat break down than regular. Also it lubricates better in these applications. Even wheel bearing for disk brake has a higher than normal heat range. Now regular hub/wheel bearing grease does not have a high enough heat range because of the heat from disk brake applications.

There is specifications listed on the back of the grease bottle. Ones like HS (hi-speed) EX (extreme pressure) MN (marine) MP (multi-purpose)

Check this out! Timken grease for their bearings which sould be the one your using or close to it.

There are 2 basic greases you want in your arsenal:

1. Wheel Bearing Grease for disk brake applications. (Muti Grease) With specifications for your intended use.
2. Moly. Engine building and sealing and other work.

 

Nope. but it only takes 32 seconds to remove the bolt with a 15mm socket and rachet.

 

Thanks for the details. The original grease was thick and dark so I shot some thick and dark type stuff in with my grease applicator. I'll check the label on the grease when I get home.
Do you think greasing it will cause it to fail?
