After this date use motor p/n " 3 On units built before 3/03 use p/n (base mounted). NOTE: units built between 3/03 and 8/03 may have either the base mounted motors (Code 15= 1, 2) or the belly band mounted motor (Code 15= 3). To insure the correct replacement the data plate code, or a visual inspection of the motor is necessary. UV; UAHB,UAHF,UAHR,UAHV,UAVB,UAVR,UAVS,UAVV Des. D&E Rev. M 12/17 RPL / Page 7
