M103 Air Pump Hell

Experiences sought on this one. My 300TE has a freshly rebuilt air pump with only about 4 months use or about 6k miles. The front bearing is screaming on it already and it's blowing that burnt red dust out that is reminiscent of the last pumps front bearing innards. I replaced the vacuum check valve upstream of the air pump with a brand new valve when I replaced the air pump.

Has anybody else had this short of life from a rebuild. I think the pump is seized again, I'm going to try to turn it by the nut on the clutch tomorrow. I disconnected the pump electrically and it seems to be running without all of the painful noise, so I'm going to be checking my warranty out on it. Hopefully it was a 6 month warranty and not 3 months.

Your inputs are greatly appreciated.
