Craftsman - clean oil in the water
30 gallon, oiled, two cylinder, belt-drive. 200 hours on it to date. I like to run the machine for a couple of seconds on start-up to blow any residual water out Yesterday I noticed clean oil in the water. Should I be worried?
All oil lubed compressors put compressor lube oil into the compressed air stream.
If you've just noticed this happening, that suggests that you are getting more piston seal blow by, and, also suggests (not surprisingly) that you have wear inside your cylinders.
The amount of oil is something you want to monitor.
That compressor oil is not good for Buna N seals.. sometimes it eats them, so if your air use includes appliances with rubber seals, you'll want to remove that compressor oil before it gets to the seals. (COALESCENT FILTER)
Make sure your oil sump is topped up, and continue to monitor. Too much oil will tell you it's time for a tear down and fix up.
919.152810 - Craftsman Compressor motor has shot bearings
My Craftsman 919.152810 motor died due to shot bearings. The drive end has a bearing pressed into the cast aluminum pump housing.
I removed the armature from the motor, and was able to move the cast aluminum pump housing far enough to cut the outer race of the bearing in order to get the pump casting off.
Unfortunately, in the process, I cracked the internal motor cooling fan (NOT the external squirrel cage fan), which is molded over a knurled sleeve.
The motor is an A. O. Smith MO-3024.
Do you know of any source for either a replacement motor, or replacement parts?
If I can get the internal fan, I can replace the bearings and get this thing working again as the armature and fields are still in good condition.
Thanks for your help.
