Greasing Mastersbilt bearing birdcages

[kevpow]

So i'm doing maintenence trying to get ready to run in the next couple of weeks and one of the big things was to clean and grease the bird cages. They are the WMF Mastersbilt sealed bearing cages. Are they greaseable? How do they stay lubed? Just wondered what I needed to do to maintain them. Thanks

No they are not greasable. About the only thing you can do is keep the birdcages clean and free of dirt and sand each time you go to the race track.
