HOW TO DISSEMBLE MOTOR AND INSTALL PARTS
Motor housing has 9 screws (refer to Screw Index below).
It is very important that when you reassemble your motor, the screws are installed back in the locations shown, otherwise damage can occur.
When reassembling, DO NOT over-tighten the screws because that can crack the housing and cause other damage.
