Boca Bearings RC Newsletter: Issue 14

I swapped my 700MX bearings for Boca Orange Seal Ceramic bearings right away. I wanted to run Align motors, but listened to the feedback here on RR on early bearing issues. So I went Boca from the start.
I took some pictures to show the process in case anyone wants to do bearings and was apprehensive about the process.

High level summary of steps
- preheat oven to 225 degrees
- remove rear grub screws securing shaft in back of case
- heat the motor for ten minutes to loosen bearings
- Push shaft out of case
- remove old bearings
- install new bearings
- reassemble motor
- replace rear grub screws.

Q: The bearings I received have a green shield on one side and a black shield on the other. Should either of these be removed on the back bearing? What about the front? Are these colored differently to indicate direction or does this matter?

Firstly the different colored seals do indicate which is the open side on the bearing. The green seal is the one to remove to expose the open side. However, on the front bearing there is no need to remove either seal. Keeping both seals on offers better protection for the bearing. These bearings are lubed with grease and the seals will keep the grease in for the life of the bearing so there is no need to worry about lubrication. With regard the rear bearing both seals can be removed if needed and is probably advisable.
