I recently had the fan housing cerakoted and now I want to do the transmission. On the fan housing I removed all the grease and oil and the shop that applied the cerakote blasted it withe 200 grit aluminium oxide in a cabinet and it came out great.
I will get all the grease and oil off the transmission, but the blasting will be done with 100 grit aluminum oxide outside of a cabinet. I believe I have protected everything but was a little concerned about 100 grit being to course.  |

I've only used crushed walnut shells for whole gearboxes. I'd be concerned about a real hard/aggressive media getting inside.
The heavy duy foil backed duct tape really helps protect unwanted areas for media blasting. |

The heavy duy foil backed duct tape really helps protect unwanted areas for media blasting. Thanks for response I am concerned. I have packed hard around the bearings to the drivers. I don't know what to call the area. If I can get the area 2 to 3 inches away from bearings and tape this off would that relieve the biggest concern |
