get some diesel fuel,...it works as a good de-greaser. then an air compressor to blow them out

You will be sorry if you dont replace them w/ new ones.

Thats not grit! It's "Go Fast Powder"! Eventually, your bearing will really "go fast"!
Try flushing them out by pumping grease though them if they have a fitting. Grease till it oozes out, turn the wheel a little, repeat.... Otherwise, try dissolving the grease that is areaby there with WD40, kerosene or a dedicated degreaser like engine cleaner. Then blow out the bearing races with compressed air. Good luck., efxguy |

No way-no how gonna' get them clean now. Chuck 'em and put in new. Save alot of trouble/cost/damage in the long run

Best advice yet. Sand, even for a short time fucks up bearings. If you have ot clean them use a high pressure aerosol cleaner like brake cleaner that wont damage the seals. Some types will eat plastic. You can try soaking them and then hitting it with air as well. Still replacing them is the best bet. CH |

1. Remove bearings
2. Soak in degreaser 3. Clean with compressed air 4. Pressure lube 5. Repeat 1-4 twice more 6. Throw in trash and buy new bearings

What kind of bearings?
Ball? Roller? Tapered roller? Needle? |

Like a few others have said, you should just replace them.
You will never get them clean enough, and they will fail at the possible time. Just throw them away and put in new ones. |

They are open cage. and not have been moved since the grit got on them. So they should be cleanable!

Clean them with brake cleaner, soak them in a degreaser, rinse with water, clean with brake cleaner, repeat until all the dirt is gone. |

non-chlorinated brake cleaner, follow up with a light blast of compressed air

If you must, then soak them in a bath of hot oil for some time then hit them with some solvent in a parts washer to hopefully remove the grit. If it's a open caged tapered roller bearing there is a little more clearance and the hot oil should help that open up some. Stay away from the compressed air, one of the worst things in the world for a bearing is to spin them w/o a load, at any rpm. With the air you'll just wedge anything that is in there into the race even more and your failure curve will be pretty quick If it's for a new bike, your efforts are worth it as you can't go to the local napa or Applied Ind. Tech and pick up a replacement. Chances are the ID is normal but the OD is some off standard special that the bike shop will hose you for. ETA: SWINGARM BEARINGS BY ANY CHANCE? IF so, IM me

Bearings are what--$15? Clean the spindle good--then put a new bearing on.
You will spend two hours dicking with it, then it will still fail after a little while. New ones are cheap.

Put new sealed bearings in it, unless the quad has an aftermarket carrier. If that is the case, then you might need to get tapered bearings with seperate races.

Buy new ones, and ceramic if you can afford them. While you have the cases split, do it. The sand from the blasting process probably ruined the race |

I would agree with all who have said to replace the bearings...
You will actually be money ahead replacign the bearings than to have to clean everything and the man hours invloved in that... now if you are still adament about cleaning them and the cost of new bearings is so godawful prohibitive that you have no choice but to clean and repack... take the hubs apart, with a RAG wipe off all remaining grease and grit without turning the bearing... get everything off that you possibly can... Now soak the bearing in a can or pan of solvent (mineral spirits works fine) let them sit there for a while whilst you clean all the garbage off the spindle, same method, dry rag, then rag soaked in clean solvent, then after you have done all of this... take the Brake Cleaner and spray everything, soak it until the Brake Cleaner is dripping off... now use air to blow the brake cleaner out of the bearings (do not allow the bearing to spin) spray again with Brake Cleaner and repeat with Air... then repack either by hand or with a pressure packer... and put back together... figure you spent more in man hours than the bearings were worth... unless they are the special super unobtainium Type R Racing bearings that you can no longer get and Timken or CR do not make a replacement for......... However even after all this there is probably some grit that you did not get out and will come back to haunt you.. and in about a year you will replace the bearings anyway... |

If they are open cage bearings and you haven't rotated them since the sand got in there, and they were good bearings to begin with, clean them.
Here's where I'll get flamed (as it were). In my years of working on cars, I'ev only found one thing that completely cleans out bearings: gasoline. If you choose this route, do it outside and away from the house, and use a steel container/pan and swish the bearings around in the gas for a minute or so. Trust me, no grease will be there when you're done. DO NOT blow them off with compressed air, causing them to spin. You could damage the bearing and your finger.All other methods pale in comparison. |

take it from me...
REPLACE the bearings. This is what I do. There is no way to recondition this type of bearing yourself. The geometry of these bearings is critical to their holding a proper oil wedge and providing adequate cooling. Don't do a poor-boy fix and regret the reduction in life and quality of operation that would surely result. PITSNIPE OUT |

Assuming he was accurate in his post about the situation.... The bearings don't need to be reconditioned. They're not sealed bearings (race and cone), and are not worn out. He did some sandblasting and got sand on them, and needs to clean the grease (and thus the sand) out of the bearings before using them again. As long as they weren't used with the sand in them he'll be fine, assuming he is certain the bearings are otherwise good. Fat_McNasty - how much use did the bearings have on them? Could they have been suspect at all prior to getting sand on them? If so, replace them. If they're known good, clean `em up and repack them. ETA: Don't mix up the races - know which race goes with which cone. If you get them mixed up, you'll need to replace them soon anyway so buy new ones. |

Just don't let 'em spin or they are toast. Anything that dissolves the grease will clean them.

Well an hr and a half in the ultrasonic cleaner did the trick! They had maby 40 hrs total on them before the blasting!

Too late, but, what about sealed bearings? They're like $30.00 and are really the shit especially if you ride in muddy sandy areas. I replaced mine with Highlifter's sealed bearings. It was a bitch getting the old one out (interference fit), but well worth it. Don't see them on Highlifter's site anymore. Here's some that are similar: Example of sealed bearing bd |

Replace them. It's the only smart choice.
Once damaged by abrasives, they'll never be the same again, and will wear very quickly even if totally cleaned now. But with small bearings with no seals, you can at least have a little fun with them by washing them in mineral spirits and then blowing them dry with an air nozzel at 200 PSI. Mount the bearings on a stick and get out of the way of the shrapnel path, and see if you can spin the bearings up over 100,000 RPM with the air nozzle before they EXPLODE due to centrifugal force!
