On these pictures you can see an ended Linde BMV140 variable
displacement motor, used in a closed loop transmission of a forest
crane. These transmissions work in harsh conditions and are often
subject to severe pressure peaks, which, in this case, resulted in the
cracked end cover.
It is interesting that, despite the damage, the
transmission could still function in one direction, and the machine
managed to propel itself for quite a long time to get to the workshop,
where the motor was dismounted.
