(DD) Brake Seal (8) New Brake Seal (9) Former Brake SealNew drive motors include the following improvements:
A new configuration for the brake piston seal (DD) is included in the seal kit for each motor.
A new configuration for the piston ring (AA)
A new configuration for the cam face seals (BB)
A new design of stop pin (CC) between distributor and rear case
A design with three dowel pins (5) and five M10 bolts in place of the one dowel pin and eight M10 bolts between the brake housing and the motor housing
The seal for the 2 speed spool was moved in the 280-7858 Piston Motor Gp in order to fit in the rear case instead of in the brake housing.Table 1 lists the former drive motor, the new motor and the machine application.
