What type of air compressor do you have?
Is it a single motor\pump combination is the pump and motor separated by a fly wheel? If it's the first one don't waste your time or your money. Hard to find parts hardier to justify the money if you do.
If it's the second then you should make sure you can get a rebuild kit and replacement parts. If you haven't already.
Assuming you have anyone of the more common pump brands like Dayton, Champion, Ingersoll Rand.
Dis-assembly should start with the top end. Remove the head and valve plate then the cylinder head bolts and cylinder head. Remove the wrist pin\pins and piston\pistons. Next remove the lower rod end caps and pull them out taking care not too nick the crank bearing journals. Remove the front crank cover and and (if it has one) the rear bearing cap\plug. You should be able to remove the crank through the front access. You may need to tap the back end of the crank clear or the rear bearing.
The bearings will probably need to be pressed out.
Unless you have a pump that is considered non serviceable or is an oddity this should do it.
If your pumps layout differs from the norm or you just need more specific information please let me know. Just include the make and model and I'll be glad to help you out. Good luck.

to be honest a non lube pump design is problematic at best, if you use it for any length of time they just do not hold up, money well spent in a oil lubricated pump you will be far happier!

Your unit was most likely made by Porter Cable and parts may be matched at your nearest Dewalt parts center. The best way to remove the bearing is to use a press, however the fast/dirty method is to use a Dremel with a thin cutting wheel to remove the bearing from the shaft. Remove the head of compressor being carefull not to tear gaskets. Loosen screw holding rod to bearing and remove rod (note position). Make two cuts on outer bearing shell and remove shell. Make one cut on inner race, then expand slightly with blade of screwdriver and remove. Use generic bearing 6203 available at auto parts. Clean shaft with fine sandpaper and install bearing to noted position. Probably a good time to replace cylinder and ring. Usually part Dewalt / Porter cable part #k-650 or use Sears part. After assembly turn several times by hand checking for alignent and free movement. Be carefull with the fan, easy to break. You probably should order a spare blade. Good luck with your repair and post again if you have questions.
