Impro White Motor 505540A3122AABAA Impro

White Roller Stator Motor – 505540A3122AABAA is a high-displacement RE 505 Series motor purpose-built as the OEM replacement for Bandit part #900-3908-67. On a 4-hole magneto mount with a tapered shaft and lock nut, it seats in a fixed housing and locks into the chipper drum or feed drive shaft with the secure, self-centering fit that sustained, high-impact processing work demands. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. With 536 cm³/rev displacement and 8,700 in-lbs continuous torque, it delivers the low-speed, high-torque output that Bandit wood chippers and compatible brush processing equipment require through continuous, heavy-load operating cycles.
