i had a great one...well no so great. just took over 6 old traction
elevators, was getting the job cleaned up and the guy with me was going over the machines. He emptied the machine drips, someone put some nuts and bolts in the drip pan and he dumped them into the gearbox!! after that we dumped into a bucket to find that 4 of the 6 had nuts and bolts in the pans. no damage was done and we drained and cleaned the gearbox.
