Porter-Cable Pancake compressor needs repair

[SkyMaster]

My father has a 16 years old, made in USA, Porter-Cable Pancake compressor.

I suspect that it takes more time, than it used to, to fill up. Also when it stops, it makes a scratchy metallic sound.

It is the model CF1400, just like that one:

My father is still using it, I do not want to dismantle it, then wait for replacement parts to arrive.

What are the parts that typically wear out in these kind of oil-less compressor, and that I should order?

I would be surprised if parts are even available. You have discovered the problem with "oil-less" compressors. The price of compressors has dropped a lot over the years and I think you would be better off buying a new one.

Brand new those small P-C pancakes are under $100 at any big box store. I broke down and bought a 3-1/2 gallon one not long ago, I think it was $89.99 at H-D during a memorial day sale.

Most all of those oilless pumps have have a one piece connecting rod & piston without a wrist pin called a "Rocking Piston", so the piston doesn't travel in a perfect vertical path. It "leans" left & right in the cylinder bore in relation to the crankshaft centerline as it goes up & down.They usually have Teflon piston rings and they do eventually wear out. I've even seen one super cheapo unit with a fiber reinforced plastic piston/conn rod! I think it lasted for maybe 50 hours of intermittant run time...

If it's making a "scratchy" noise, it's pretty much time for a new one.

The most common problem I have found when taking them apart is tired or rusty reed valves.
I have never seen any different ones no matter the make or age of the compressor.
They are a truly universal part number.
They should be well less that $20.00 per set.
If you cannot find one under your make/model number just get one for another.

The last one I did was over 20 years old.
I took the valves in to the local construction tool dealer that offer repair and parts.
I just gave them to the counter guy who didn’t bother to ask about the machine.
He just went in back and came back with the new ones.

I just rebuilt my 8 year old compressor 6 months ago. Looks to be the same model and had the same scratchy metallic sound but didn't build any pressure at all. The scratchy sound was the reed valves bouncing around after they snapped off.

Here's the parts I used:

Edit: I would skip the second kit unless you know you need it all.
