SUBJECT: NOISE FROM BROKEN CLEANING BRUSH GEARS

Noise from the PCU brush roller

gear (PCU3 section 37, pg. 87,

index #4, 5; P/N# B0652425,

B0652428). In some cases, the

brush roller gear may break and

black lines may appear, as the

brush roller does not rotate.

Variations in the PCU brush

torque may cause a large amount

of reverse rotation in the drum, which causes the brush to wear down and slip over the brush stopper, the

drive gear may then become damaged from the excessive load when trying to pull the brush back.

Two spacers in the PCU have been added to reposition the cleaning brush so it will not wear down. A

cushion has also been added to ensure that the cam does not damage the stopper screw.

FIELD COUNTERMEASURE:

Install Damper Kit.

Tapping Screw – M4 x 14
