Hi, here I go again from México, I used to be a salesman here for Nissan Forklift, And the best that I can recomended you is to check wich one is the motor, it could be a K15 or a K21, if it is a k21 it hardly damaged, cause this motor is ussualy in the 4000 and 5000 Lbs. But if the motor is a K15 we have been having trouble with the power of it after a less time.
Regards
