Lubrication
The gear teeth and bearings are splash lubricated. Aside from periodic oil changes, the drive units are maintenance-free. Oil changes are easy to do. The oil brands recommended in the operating manual shall be exclusively used.
The operating manual also gives the change intervals for the relevant application conditions. The pinion-side antifriction bearing of the output shaft is grease-lubricated for life.
Hydraulic Motors
The gearbox is designed for direct flange attachment of a variable or fixed displacement motor (preferably a hydraulic motor).
Multiple Parking Device
The standard supply scope includes a spring-loaded, hydraulically released multiple parking device arranged on the input side. The multiple parking device is not a service brake.
