Depends on what blasting media they are using.

 

I did a cb750 engine a few years ago with walnut shells, and despite all my efforts at sealing it up, I still ended up with media in the engine. fortunately it was walnut shells, so no internal damage was done,

 

If they are using sand I would remove the engine and transaxle because the sand will get in and cause engine damage.

Basically anything with bearings or seals should be removed.

Are you taking the whole tractor there? If so, then yes, I would remove the engine. If the mower deck hasn't been taken apart, then I would lube up the bearing very heavily, as you don't want any sand getting down in there. I think I would spend the little extra time to remove the bearings from the deck, then there is no worries. Make sure you remove any plastic pieces from the tractor, as the sand will destroy plastic. If you are planning on keeping the tires, I'd remove them from the rims, as the sand will give them a real dull appearance. Good Luck!

When you are blasting, sand will get into places you never dreamed sand could get into.

   Complete disassembly is recommended from me, even if you remove the engine and bearings to salvage them and get it down to where you like it if you don't completely disassemble everything then  the rust or dirt in the seams will just bleed thru into the new coat of paint.  I agree with dougt as well, that sand will get into everything!!!! and you cannot get it back out after the fact.

    Take the time and completely disassemble it you will be much happier with the end results.

Think of it like this: if you don't want media in a part, don't leave it on.  It doesn't take much of a hole to allow small pieces into places they shouldn't be!

:ditto: what the others have said.

Sand blasting is normally done with a complete tear down. The Sand will get EVERYWHERE!

Also, one thing to remember is that the heat generated by sandblasting WILL warp sheet metal parts. Make sure they go lightly on the body panels.

 Glass bead is gentler but it still gets pretty hot.

 

For thin panels, walnut shells, or corn cob grit will work, egg shells and soda blasting would work too.

Best to remove about everything if using sand. Little more work but it will save even more work.

Sort of like going to the beach!

Ground walnut shells were used to sabotage german equipment in WWII. It can quickly destroy an engine when it gets inside. Good Luck, Rick

I didn't take any chances, it has 100 miles on it and 4 oil changes.
