Question about Air Tools & Compressors
I replaced the piston, rod and cylinder(kit from Sears) on my craftsman air comp but it won't run. It sticks about 3/4 the way through the cycle
craftsman air comp model 919.165400
Don't run it with the head off! the cylinder will just up and down with the piston and ruin the seals again. I have three Craftsman compressors in my shop and I've torn them all down at least twice. Rather than pay for the kit, I went to NAPA and got a roll of cork gasket material and made my own seals. They don't last as long but they work great.
I'd be willing to bet your seal it just too tight. I made this mistake the first time around too. it's not a very good design as the piston tilts through the stroke. I would try putting a light coat of heavy weight oil on the cylinder wall and move the piston by hand to lube the seal.
