old champion pneumatic compressor pump
- Thread starter cdadkins
- Start date
The motor has a bouble row belt pulley ,and probably fits the marks on the mounting plate (as well as the holes) ................In my experience these old compressors need the heads cleaned out of carbon and the valves made to seat properly ..............you can get a good idea of the bearings by simply rocking the flywheel back and forth and listening for a clonk ....you can also feel loose bearings
I am not for sure if the is the original motor. bought both on market place for 50 bucks total. figured if even one was good or was worth it. can't make it much but here it is
I do not have the original tank. it is a compressor I built. the mounting holes do not live up. lol. bearings are fine. agree about the carbon. what is the proper seat for valves.

Not a lot of info on this compressor pump.
See this post:
www.garagejournal.com
for a hard to read spec sheet.
7cfm @ 100psi using a 1.5hp motor.
More HP won't help much, its got a real small 2nd stage piston.

Mystery Champion REN-14 Compressor Pump
I see some parts on Ebay and a few other vendors but no info about this pump. Like when it was made, how it compared to other Champion pumps, what hp etc.. Anyone have any info?

You struck gold if you purchased this pump for $50… I rebuild air compressor pumps professionally, focusing on Champion, Kellogg-American, and Quincy products. Those are the only three brands that will outlive my children and have readily available parts if needed. Your REN-7 should need minimal repair to get it running in top form again. Remove the four manifolds to access and remove the valve bodies. Undo the bolts that hold the cylinder head to gain access to the pistons.
The valve bodies may be rusty and perhaps pitted, but sandpaper will clean them up and get the faces in like-new condition. You could lap the valves themselves and not need to purchase a new set, but the valve springs will need replacing. The pistons and the cylinder head are almost always in good condition, no matter how long the pump has been out of use. The cylinder walls will need re-hatching (using a 3-stone hone, not a “bottle” or flex hone), and the pistons will need new rings. The main bearings and oil seals might need replacing, but those parts are readily available and not too expensive.
Pacific Air Compressors stocks repair parts and kits for the REN-7. If you have any questions, Cary Laing is an excellent resource. The Champion “R” Series pumps were designed right, so there is little difference between models. I attached a link to a service manual for a Champion REN-10, the parts diagram being sufficient to help you disassemble, repair, and maintain your unit. The Champion company is always helpful and should be able to provide you with the manuals specific to the REN-7.
If you have other questions, you are always welcome to message me.
