Still too fast, the motor pulley is big definitely, I know this type of compressors, you have to bring the speed of motor down or use smaller pulley to let the compressor valves working properly, over heating is the result of over speeding.

I'm actually surprised that you didn't figure out that the motor pulley was too big for that pump! It was making that pump spin way too fast! There's a formula to figure out which pulley to use on a motor, factoring in the RPM of the motor and the size of the pump flywheel. Wish I could send it to you, but I don't see any way to do that here. :(

You got me curious when you drained the oil on the "new" compressor and said "at least its clean".

If you are interested, to determine pump speed use: motor r.p.m. X motor pulley diameter divided by pump pulley diameter. example: 3500 rpm X 8" =28000 / 16" = 1750 rpm. That pump should run in the area of 800 - 1000. It's a cast iron unit meant to turn slow and last 20-30 years. The pump you pulled off is a disposable one, mostly aluminum, meant to last 3-4 years and toss it.

That small pipe you were looking at (the suspected bleeder pipe) is exactly as you said. There is a one-way check-valve at the top of the tank where the air enters. When the tank is full and the power is turned off, it drains the air from the fill pipe, and from the compressor head. As you said, this drastically reduces the start-up power needed, as there is no resistance on the motor or compressor until it recharges that small pipe (which takes almost no time with the small volume).

Enjoyed the video and appreciate the tip to look out for double set screws when taking pulleys off a shaft(12:20). Surprised that you didn’t clean the rust off of the inside of the hub of the motor pulley (14:10) after you carefully wire-brushed the motor shaft. A lot of people are visual learners, which is probably why most of us watch YouTube, so it would help your viewers, who are following your every move, to briefly mention or show that you did tighten the set screws on the motor pulleys when you re-attached them to the motor shaft. I am not a regular viewer, so I was a little surprised that you are so casual about electrical connections - not tightening the crimps on the power connections at the regulator switch first thing, and putting loose live wires carrying a high load into a socket, instead of spending a couple of minutes attaching them to a standard plug, is beyond my understanding of the basics of personal safety in the shop. I’ve learned what little I know about such things the hard way - looks like you are luckier than most, so far. On a positive note, you are getting good results doing it your way, but skydiving would probably be safer for you.

That pump is running way too fast. I believe that pump runs at 1400 rpm the drive wheel need to be around 2" a1750 RPM motor would take care of it. That compressor unit is sold by stores like Tractor Supply, cheap & easy for the home owner. That industrial compressor air end will kill that motor. Check your amp draw. Holy sheep shit that thing is overspeed like crazy. Keep it up & you will have something else to fix on YouTube. I've been working on pumps for 30 years. I've never seen anything like that on a serviceable pump.😵😵😵😵😵😵😵 Best of luck !!!!!!!! Most compressor pumps require a run in to seat the rings, that is normally done with the head off no load just run in. Now that you got that head hot don't unbolt it you will destroy the gasket. Slow it down moter speed 1800 max. Wow ????

Like others have mentioned your running that compressor at too high of an RPM that is why it was getting too hot. You need to put a much smaller pulley on that motor to slow it down. It was never made to run that fast.

That's not a leak. It's a pressure relief valve built into the cut off switch. It relieves pressure from the head every time it cuts off. It prevents the compressor from starting under a load. Also, never use an impact or any powered tool on a gear puller. You got very lucky not twisting that left hand threaded screw off.

Figure out the pulley ratio. That pump is probably rated at 1200rpm max. It's a nice old school pump with good valves in it. Look at the motor and find out the motor rpm. If its a 1700 rpm motor then you just might make it. But that old pump will not like much over 1000 rpm. It will cook on that giant tank. I have one just like it and I'm spinning it at around 800

Motor direction does not affect the flow direction of the air, the cylinders have inlet side and outlet side reed valves that control that by allowing air to pass in one direction only. However running the motor in reverse means that the fan is running in reverse so whatever air that flows across the pump does sow under suction rather than pressure, fewer particles of air means less heat absorbed. Fan pulley is also much smaller and with fewer blades so moves much less air, then leaves it around the case rather than over the head and cylinder, so less efficient cooling again. Quick way to check rotation direction would be to hold original fan pulley in front of the replacement, if the blades are angled the same way for both, they are both intended to run the direction. Replacement pump has probably 1/2 to 2/3rds pump volume of the original so will take a lot longer to pump the tank. The motor pulley is still too large for the pump, so it is overspeeding. Head ports are fairly small in the pumps, and they like to run at slow speeds for max efficiency so they can suck air in through the filter and inlet reed on the piston down stroke, compress it on the upstroke, then blow it through the outlet reed and tank check valve near the top of the stroke, when cylinder pressure exceeds the tank pressure. Running the pump too fast reduces the flow time available for each set of valves, and hence the output volume and pressure, and overall efficiency. Generally speaking, the larger the pump capacity the slower it runs, to allow for flow resistance, hence higher capacity pumps have larger fan pulleys to slow them down, motor pulleys are typically 2.5 to 3 inch regardless of pump capacity, unless dealing with 8HP + units when all pulleys need to be scaled up in proportion to maintain the efficiency of the belt drive system. The fine tube to the pressure switch is a dump tube, it opens when the pressure switch opens the motor power circuit and bleeds the feed tube, cylinder head, etc to atmospheric pressure to allow the motor to start turning before it encounters a lot of pressure and resistance. There is a check valve at the tank entry that only allows flow from the feed tube into the tank, so the dump tube and valve can clear the feed tube without dumping air from the tank.

I recommend putting an "Amprobe" on one hot line on your electric motor. Observe a COMPLETE cycle from start up to cut off. See how many amps the motor is pulling near it's cut off point. It might still be over loaded. It should have a spec label somewhere on it. A few drops of air tool oil in each cyl head check valve will: clean varnish off of the check valves. & give the tank a bit of corrosion resistance. Those unloader valves DO actually bleed off a bit of air at end of cycle.
