I believe your graphite shoes are too warn. When the spring is installed, there should be only about enough room to fit the spring in there. If the spring side shoe is too short, I will start to rock side to side and destroy itself. Everything must be clean and dry and use very minimal grease. If grease gets deposited on the graphite shoes or the paddles, it attracts dirt and destroys the pump. The rear bearing is very often reusable after being cleaned thoroughly. The paddle bearings are often reusable after being cleaned thoroughly. I believe the original grease was very waxy. But I have packed them with high quality wheel bearing grease. The front bearing seems to take the most abuse. It needs to have be tight and the seal needs to be nicely intact or the pump will suck dirt into. I am not an expert but I have messed with them for some time. I spray silicone spray on a towel and lighly wipe down the paddles. Otherwise, the pump can feel stuck when it isn't. No oil what so ever. The round cylinders had a graphite coating on the outside of them. Often it is partially missing. When missing and rusted, I have bead blasted and sprayed them with a type of graphite paint. It is nice stuff that is super slick. Just use light coat.... seems to work. When they were originally assembled, they had very tight clearances. I think that original coating was meant to sort of wear away or act as a lubricant. I am only guessing and I am not an expert by any means. A small dead blow hammer and a little WD40 works good at getting the rear cover off. Just tap around the edges. Don't pry it off. It can be stubborn to slide the bearing shaft out. Carefully rote and pull. Nice Video! Thanks

Can you purchase new blades for these air pumps?
Do you know where I can get replacement shoes for this?
Hello The vain shoes look longer on one side. What are the dimensions of them? 5/32" x1/4" x 3' long?
Hi, where do you order the carbon shoes? I have changed my bearing but cant find any shoes.
Did you ever find the shoes for the smog pump/
Should have recorded the disassembly. Wow.😂
