AW55-50SN Planetary

The AW 55-50SN transmission has many problems and one of the chief is with its bushings. The planetary bushing fails most often and we are seeing stator and sun gear bushings spinning out also. To solve this problem we have developed a one piece bushing which has greater holding power in the planetary. The planet must be machined to accept the one piece bushing. Since the machine work involved is complicated we're offering exchange planets with the one piece bushing already installed.

There are two different planets available in the AW55-50SN transmission. See the picture with the red line in it that shows where to measure to be sure you get the right planet. See below for correct size and part number.

1.860" = Part # 31255

1.765" = Part # 44255

There is a $100.00 core charge that will be refunded if the planet you send back has at least three of the four planet pins snug.
