I'm getting ready to have a tractor blasted for my eldest son and the blaster is trying to tell me it would be ok to blast the transaxle, the tcv and lines are still attached to it although I could remove them, I think that it would be to risky. My original plan would be to just wire wheel the transaxle the best I could.

I would think if all the gaskets and seals are good you should have no problem when we have cars done they do rearends when done blasting wash out with diesel and put in new oil.

Will they be using silica sand or some other media? Oftentimes, you can blast with a media such as sodium bicarbonate (baking soda) and you would have no problems at all. I've had aluminum engine cases blasted and it worked great.

I have all of the fittings capped off with cap plugs and I would have to remove the long frame attach bolts out of the transaxle and put in short ones to tighten the cover down.
Realbiker I will check to see what medium he is using, but I am leaning against this idea.

Probably the safest thing to do would be use good old fashioned liquid paint stripper and wire brush. May take a little longer, but you won't have to worry about anything getting inside.

I sand blast a lot of things but I have never blasted a machine where the sand will get anywhere near seals that seal out grit from an internal lubricated cavity. The reason I don't is that some years ago I was given an 8N Ford tractor that had been blasted then painted. ALL the wheel seals and any other seals had sand blasted against them and under them. A real mess. And of course seals normally have a little oily weepage near them that will be a great place for sand to stick.
When I blast things I'm always amazed at how much sand ends up in places far from where I'm blasting. I would not even tape off seals a foot or more from where I'm blasting and expect them to be ok.
Sand blasting is a great thing but you sure do want to be careful where you do it.

Yeah I agree with you guys and I know better, taping anything up would be a waste of time as sand would still get in there. Using stripper would be a better idea, actually if I was going to paint this the same color I would just clean it up and paint over it.

It will be a **** of a mess. If it was mine I'd spray on some degreaser [Dawn dishwashing detergent is great] and the power wash it. Hot powerwash if you can. Then wire brush rusty spots, wash again,dry, prime and paint.
I clean machines similar to that every year and thats nothing I would sand blast.
I was typing while you posted your edit.
You are on the right path in my opinion. Good luck!
I'd offer to help but I hear my mother calling. :ROF

I've blasted gear box housings and if you mask up the outside of the seals etc it'll be fine. Of course a little finess when blasting is key. Being careful not to aim right towards seals etc. Use low pressure and get it stripped right. i did my tiller, an old Gravely rotary plow gear box etc. Also did the ram on the splitter I used to have.
No issues with any of them. Used Plastic media and also Aluminum Oxide 240 mesh grit.
Plastic tears paint and rust of quickly. Grit removes the oxide layer and really cleans the surface to bare, raw metal.

Housing does not look that bad. I would not blast it unless your taking it apart. I would probably pull that cover off and blast it though. Heck... you want to pull it to check the bolts anyways right??

I'm just going to take the cover off and inspect the bolts inside, I don't plan to tear it all the way down.

Then I would just blast that cover. it looks pretty rusty. Other then that, just wirebrush, and sand the housing.
:ditto:
Also try Weslys Bleach White. It has a very strong surfactant. (LYE)
DO NOT USE WBW on painted surfaces unless you plan to re-spray.
And keep it away from polished aluminum!!!!

They also use ground up walnut shells to blast with. They are cheap and bio-degradeable...
