Sandblasting 12 Bolt
Hey,
I'm taking my 12 bolt rear end on monday to get it sandblasted. What should I do to keep sand from getting inside? I've heard of stuffing greasy rags in around the yoke, or taping it up good. Anything else I need to seal up? Thanks!

the smart thing is to strip that housing naked and blast away

exactly strip the houseing clean then blast it and wash it real good to get all the sand out. sand will play hell with your bearings

well the vibe i'm getting is that I should pull everything out, blast the housing, then put everythign back together with new seals etc.
Your right, I'd rather not do this twice, I was just under the impression that I could safely blast the entire assembly at once. Here's the Q. What is involved in breaking everything down? is this something that can be done easily in an afternoon/day? When putting it back together do you have to set up the gears etc. again? As you guys can see, the other kind of rear ends are my specialty

You can blast the rear as a whole unit. Any sand blaster worth a crap can and will protect the front pinion seal area and end axle tube areas with no problem. I pulled axles, seals and bearings (I was planning on replacing bearings, races and seals) and made plastic plugs for axle tubes which hammered in place. I left the ring and pinion with yoke and cover in place.

I have done them both ways. From experience, it is hard to
get all of the sand and residue cleaned out. I prefer having everything in place. I will take string and tightly wind it around the seal and yoke ends until it is built up enough to cover the areas. I then try to blast away from the areas as much as possible. When finished I either unwind or cut away the string with a sharp knife. I am much more confident doing it this way. EdB |
