Abstract
A sewer pipeline cleaning apparatus comprised of a hydraulic motor removably mounted on a frame, connected through a fluid connecting adaptor to a high pressure hose. The hydraulic motor and the fluid connecting adaptor are both removably mounted on the frame so that they may be easily removed for repair or replacement. The motor is mounted in a cylindrical ring attached to the frame and secured by locking screws. The fluid connecting adaptor is mounted in a second cylindrical ring attached to the frame, axially aligned with the first and is secured in the ring by a locking screw. The fluid connecting adaptor is provided with rearwardly facing orifices connected to a passageway through the adaptor for applying a thrust to assist in pushing the sewer pipe cleaning apparatus through a pipeline.
