I purchased a brand new M90 blower a month or so back, put it on the car and am now having problems. It seems that i can grab the pulley and slide it in and out the case by about 2mm, i checked the other M90 blower we have and it does the same but to a lesser amount of maybe 1mm. Is this normal that you can move the pulley, it's not the pulley sliding on the shaft, it's the whole pulley and shaft moving together.
Thoughts?
