Air Pump problem
OK, I just picked up my pump off the bench that has been off as I rebuild the top end. I went to give it a spin and nothing
I believe that in my zest for only clean good looking parts going back on the engine I suspect some water may have got to the unit, maybe temporarily seizing it????? I was thinking to shoot a little WD40 or PB Blaster into the pump and see if it frees up, sound like a good idea?
I just can't believe I might have to fork over $50 for a part that I don't even want

Well, I guess hitting it with some lube or the PB can't be too bad considering it's function in life. Never thought about gutting it, but I do have to pass emissions here in ATL.

I hate to be the bearer of bad news but I gutted my pump and I soaked it in WD-40. I had to take a hammer and chisel and open it that way. Took about 20 minutes. Smashed the fins out. Lubed it up REAL good, I used loc tite to put the bolts back together to make sure it wouldnt break open(I learned that after I tore up a 40 dollar belt). No problems and it still looks stock!

I just broke it open and cleaned the back plate, then slapped some lithium grease into it. It spins OK, but not great, I worry that it might lock up and then of course eat or toss the belt.

What's the process for gutting it? How did you get rid of the fins! I assume those are the two fins that go through the interior cylinder. What lube did you use.

Mine was making a aawful racket. Take a hammer and just smash em out. If it locks up on you, say goodbye to the belt and hell to 100 dollars instead of 50. I need a eliminator pully.

OK, the pump is not moving that smooth so it is either gut it or replace. I don't want to invest $50 in a new one but I'm not really sure about the process to gut it. Can someone give me a good step by step pictures are even better.

I actually lubricated mine with lithium grease thinking that would work well on the bearing. But I think some how it gets hung up with the fins, although I don't really know how these work.
If I don't get any good idea in a day or so I'll have to replace.
