Sandblasting engine cases

[SplitSide]

Hi there just wondering if it's ok to sand blast your engine cases thanks

[SplitSide]

Is there any spots you don't want sand blast or is everything ok thanks

Ok thanks

Sealing surfaces I try to avoid. But as long as your not against the surfaces with the gun you should be okay. Just don't go crazy

Stick them together, tape the clutch side off, tape the bearing openings on the stator side and the stator cover mating surface. Blast on...

 

Give eagle one wheel etcher a try if you don't have access to a blaster.

Isn't soda blasting or walnut a better option for cases?

I used a combination of walnut and sand in the blaster I was using. I went to harbor freight and picked up a few things. The sand did almost nothing. The walnut shells worked well. I will try glass bead and steel shot one day too

Put some old bolts//screws in all threaded holes. U don't want sand in those

I use glass media and I hit everything , pull all bearings seals , after blasting I run tap through every hole, wash with hose, then I go inside to my wife's sink use hot water and dawn , scrub all mating surfaces and anything else you feel needs it. Blow it dry , ascetone mating surfaces with white terry cloth and you'll know rite away if it's clean enouph

Ok thanks for all of your help

Agree with above, I would select a less harsh media.  Soda, Walnut, or dry ice.  Sand will actually open up pores in the Aluminum and it will stain rather easy.  Glass seals the pores but still is a little aggressive IMO. 

 

You may also consider clear coating the cases if you sand blast to seal them.
