At the minimum the bearings need to be pulled out and the whole case washed/cleaned thouroughly before reassembling and running.
I had a new p5x of my own that sucked dirt, enough to wear the crank .005. I did quite a bit of playing around with this one, tried with only a little bit of luck to drill out the crank pin and press a new one in. One weekend was the longest they would hold. I finally put a Go crank in it and it Tq'ed a pro series race in a truggy.
Like Ray said you need to go a tad tighter with one that sucked dirt or is scratched.
