Bosch Rexroth AB, Version 11.2019, RE 15305-WA

7.4.11 Flushing

To avoid high temperature in the motor case the heat must be removed, because
high temperature gives lower viscosity and that gives reduction in basic rated life /
service life. The motor case must be flushed when the output power exceeds the
max. values.
High temperature in motor case
Reduction in basic rated life/service life.
▶ Max. power without flushing:
CA 50 and CA 70
CA 100 to CA 210
For calculation of required flushing, see
Bosch Rexroth representative. The flushing oil shall be drained in the normal
drainline, see chapter 7.4.10.
Connect the input flushing line at the lowest drain port, D1 to D3 at opposite side
compared to the drain outlet in order to obtain a cross flushing flow through the
motor, see Fig. 53 and Fig. 54.
