BEARING BUDDY II W/AUTO CHECK
When hub is full of grease, the blue auto check ring rests about 1/8" outward from the steel
retaining ring. A spring loaded piston behind the auto check ring pushes against the grease which
generates pressure inside the hub to keep water out, thus offering true bearing protection. If the
lubricant is low, the blue auto check ring will recede until it is flush with the steel retaining ring.
Add a small amount of grease to move the blue ring slightly outward and restore pressure. Fits
hubs with 1.98" opening.
