How To Tell If Bearing Buddy Has Enough Grease

Question:

How do know when to add grease to a bearing buddy and how would you know how much you are adding? Thanks.

The great thing about Bearing Buddy like part # BB1781 is that when you add grease to your system with the included fitting, it will move the spring-loaded piston outward and allow grease to seep around the edges to keep from damaging the seal.

You can manually check the Bearing Buddy to be sure it has enough grease. All you need to do is press the edge of the piston. If you can move or rock the piston it has enough grease. I have attached a drawing of a Bearing Buddy you can check out to see what the components are.

I have attached a link to our product page for Bearing Protectors you can check out. I also attached a helpful article that explains how to replace and install bearings, races, and seals you may want to take a look at.

If the piston does not seem to move during the greasing, should I keep putting in grease until it does move?

You should basically keep adding grease until you actually see grease start to seep around the edges of the piston and into the barrel. Don't worry about the actual piston movement - it'll do its job when full.
