Drive Gear Middle Fleck 9000, 9100, 9500
Be Sure to Check the Condition of the Middle Drive Gear (1513502 ), as this can sometimes be the real reason the valve is not turning.
Also, the Gear usually strips because the Main Pistons and Seals need to be replaced.
Guide Pin ( PN 15323 ) , for 9000 was discontinued.
Guide is now built into the Middle Gear ( Fleck # 1513502 ).
There is no longer a separate "guide" used on the middle gear.
The middle gear ( 15135 ) now incorporates the "guide" in the one piece plastic mold.
The new resulting Fleck part # is 1513502.
