Well.....I got this new (to me) 80 gal compressor. Was going to put an aftercooler on it and start painting my truck. Every connector I pulled was full of oil. I checked the oil that was in it and it looked like motor oil (if detergent, then rings are bad). Figured I'd pull the head to look at the pistons and found it, and the air filter box half packed with mud. Remnants of mud daubers....ALOT of them. So figured I'd be cleaning / refurbing everything, so pulled the whole pump apart. Found an NOS gasket kit. The bearings (Made in Yugoslavia) were also shot. Found NOS US made ones to replace them too. So figured while I waited for the parts, I'd open up the electric motor and check the 30 yr old bearings out.
What I found there was the entire case, except the area where the commutator spins, was totally packed with mud.....more mud daubers. I chiseled all of it out (about 1/2 a coffee can full) and rinsed it with 3 cans of contact cleaner. Bearings were also toast - the governor was cracked and the contacts were worn down. Took it all to a local old school motor repair shop downtown where they had everything on the shelf.....still made in USA. ATM am waiting on them to do their thing to the (made in TN) motor. UFB it ran as it was.
So I got the pump rebuild parts a week ago. Soda blasted the case, honed the cylinders, and all new rings, bearings, seals and gaskets. Also needed a site glass. Wife said it looked so nice it made the tank look bad (was decent but lots of chips and scuffs), so I masked off the labels, sanded it down and 3 coats of Regent Red (Coleman's original color). Just finished it last night. If I get bored, might buff the tank....dunno. All that red on the floor is from the sanding. It cleans up pretty easy.
Up on the wall behind it is my 26" 40yr old Dayton fan thats getting the overhaul next. Too hot out ATM.....so has to run.
