I have built a Steel Workbench / Welding Table and have painted everything except the top since it would just get beat on and scratched anyways. I thought I would just wipe it down with oil to prevent surface rust from forming but then thought I'd ask what others have found that works good to...

The Fafnir Bearings are what was on it originally and are what I will be putting back together with. They are sealed on both sides. The ones pictured are them. They look the same on both sides.

It had drip oilers on it like the ones below. The compressor was in a machine shop for many years. I believe they added the drip oilers. The bearings were still like new. I was planning to put just the manual fittings on like the ones pictured.

I have a 1950's 2HP 240V Electric Motor on a Kellogg Air Compressor, same era and probably the original motor. The motor has drip oiler bottles to lube the bearings on each end. The bearings are Fafnir 206KDD Single Row Ball Bearings. Both sides of the bearings are shielded. What type of oil...

I used an engine hoist as others have mentioned. If you need to lighen it up, you can pull the pump and motor. Also make sure the tank doesn't have water in it. The last used compressor I moved for a neighbor I could not believe how heavy it was. I opened the drain valve and about 20 gallons of...

A simple air wound blowing should tell you if the 20 PSI is correct. Did you check to see if the bore and rings are good?

I'm going to take a closer look at the motor and possibly reuse it. I rung out the motor leads and have continuity between them with no short to ground. I plan to pull and inspect the brushes and replace if needed. I'll also pull the armiture and clean, inspect. I'll also check the bearings and...

So based on that chart, does that mean if I have a 2 HP 60 hertz motor with the 6" pulley turning the pump at 783 RPM I will only be able to reach 125 PSI but if I run the pump at a slower RPM it will be able to build higher PSI? The CFM is more important to me. All of the tools I use require...

I recently went down the same road you are. In the end, the cost to piece a unit together versus buying a brand new unit (same pump and motor) is so close, it doesn't make money sence to piece it together. In my case I bought a good used Kellogg 80 gallon tank for $150. I priced an Eaton 5HP...

I'm not sure what the original motor is since there is no data plate on it and no witness marks showing it ever had one. I thought about tring to restore it but not sure if it would be worth it. Here are a couple pictures of it below. It has two clear oil containers on it (marked by the yellow...

I have a 1950's - 1960's era Kellogg Model 321 2HP 2 Stage 80 Gallon Air Compressor that I recently rebuilt. I want to replace the original motor with a new one. The pump can run at 400 to 800 RPM. It has a 14" Flywheel. My motor choices are either 1750 or 3600 RPM. Cost is about the same. If I...

Thanks everyone for the advice.

I disassembled my Kellogg 321 compressor pump to rebuild it and everything was going good until I tried to use a bearing puller to pull the bearing from the crank shaft. It won't budge. I also tried to heat the bearing to make it expand a little using MAP gas on a torch but still won't budge...

Thanks I found on Timken's website they also have a search feature. https://www.timken.com/engineering-tools/bearing-search/

I was hoping there was an online chart somewhere that showed: OD's, ID's, and Thicknesses so I could get a part number and maybe who makes that size bearing?

I'm located near Detroit.

Hello Everyone, So I have a 50 year old Kellogg compressor I would like to rebuild. I found a place that sells the replacement cone and roller bearings (looks like a regular trailer wheel bearing) for the crank shaft but they want $110 each for them. So, I thought maybe I could find a chart of...

I would contact Pacific Compressor or one of the other Compressor parts suppliers and find out if a rebuild kit and tech sheet is available for it and get an idea of the actual cost to return it to good working order, or if it's even possible. Also see what the HP and CFM output is for that pump...

Fairmont and Martin offer great quality. They are pricey but if this is for career in Autobody where you will repeatedly use them on a dailey or weekly bases, they are worth the investment. If you are a weekend warrior / hobbyist that will use them a few times on one project and then not touch...

If you add another tank it will not increase your CFM or PSI. The stored air will last a little long before the compressor kicks back in but will take that much longer to refill and kick off. If what you currently have is not enough PSI or Volume, then get a bigger pump and tank. Sounds like...
