This client called esmaly-werken with this problem. The mechanics worked on the shovel and when they dismount this piece off the engine and broke several bolts. This mechanics started with drilling holes into the broken bolts, but because they were very hard it was almost impossible to do this job. esmaly-werken started with this job and several hours later we were finished and put new bolts into the holes.
