Excessive backlash between the blower timing gears usually results in the rotor lobes rubbing
throughout their entire length. This usually is on the trailing (close clearance) side. Replace the
blower(s).

may affect the air flow. Servicing of the screen consists of thoroughly washing it in fuel oil and
cleaning with a stiff brush until the screen is free of all dirt deposits. If broken wires are found in the
blower screen, replace the screen.
