I made a post earlier about rebuilding my SS5 but I also started getting into the territory of replacing the pump entirely. I use a lot of hair for HVLP & Sandblasting so I need the best motor for my buck. I am leaning towards the Eaton APP3Y0518S (Single Stage?)...

The bearings are good, no play detected and it spins freely. Unfortunately my dad hammered the crankshaft with a block of wood because he thought it would protrude out the other side of the cast block which I protested.

Yeah I figured I was over thinking it, I'm used to building performance engines. Sounds like a good idea, I don't know if the electric motor would like that though. And as far as the bearing, I think you're right. I was wondering why I couldn't find any bearing material.

Thank you, I actually have a nice machine here to make gaskets for me. I just have to draw it on fusion 360. I‘m having a hard time sourcing the journal bearings but they have knock off IR connecting rods. I kind of want to test my luck with them. How long do you think the break in period needs...

I might be overthinking this, but I wanted to start a discussion about rebuilding compressor pumps. Recently, I took apart my 2019 Ingersoll Rand (SS5) compressor pump and discovered a broken connecting rod and a seized bearing. There was plenty of oil in the pump so I'm unsure why it exploded...

Yeah it's drained completely. I just tried to turn it right now and that thing is not budging. I'll have find some screws tomorrow to put on the pulley and turn it.

I'm pretty saavy at building car engines but my brain is a bit checked out because of this lately. I'm going to tear it apart and see if I can find some damage.

Perhaps I should try putting a socket on there and turning it? I was under the impression it should spin as easy as a ball bearing but you're right. I yanked it pretty hard but with just one arm (the compressor is jammed up in a corner but up against a cabinet)

I've got worst news, as soon as I got home I realized that I haven't checked to see if the pump was seized up causing the electric motor to struggle. It's as I expected, apparently for some reason the pump seized up out of the blue. I drained the oil and it was clear as day but at the very end...

I'll check when I get home tonight (it's currently sitting at 60 psi when I checked the regulator), I'm going to stop by and order extra capacitors at my local graingers just incase. I don't believe the motor is seized up either, it was working fine. It spins freely.

I have an Ingersoll Rand SS5L5 air compressor and I noticed the electric motor spinning freely because of the belt tension. As soon as I tensioned the belt, I hear a large humming noise and the electric motor shut off. If I release the belt and turn the motor on, it continues to run and spins...
