Hey guys, well, I just bought a used 01 yz 426, and the short of it all was just before I put the bike in the truck to take her on its first hard ride (after all my maintainace), while I was blasting around the sub division the water pump started pukeing coolant out of the relief port/hole. No big deal pulled the side cover off the bike and stripped the water pump. My question is how much play is normal in the water pump bearing/shaft? The bearing itself has no play either way in it, but the shaft does have a slight (maybe 10 - 20 thou at the most at the very end of the shaft (impeller end)when placed in the bearing) wobble. The shaft is not bent, and I took a micrometer to the shaft and it is not tapered so I did not buy a shaft/bearing. Just the seals. What do you guys think, what is the norm? Being a two stroke rider my whole life, and the little bit that I have rode it, I LOVE this thing. That AP pump needs some tuning though, damn does the thing cough when you crack it off an idle.
