(2) between the output shaft and shell bite bad: when the fitting clearance between the output shaft and shell through the hours, will lead to motor killed or crawl, when the hydraulic oil contains impurities will happen. The solution only replace matching output shaft and shell.
(3) set the daughter matching planar fit clearance is too small, as previously mentioned, BMR series motor fixed daughter plane clearance should roughly control in the range of 0.03 mm to 0.03 mm, if the clearance is less than 0.03 at this moment, may occur cycloid gear and the plate or the back of the side plate bite, then find the motor running is uneven, a card or a card, in severe cases can make the motor directly killed, lead to not turn.
