But mainly I worked on Oil and Gas rigs and Off Highway equipment. Done a little ZF marine gears but mainly ZF Powershift transmissions they use in construction equipment. I work for Palmer Johnson and a number of years ago we bought Mill Log Equipment up in your area, you probably heard of them.

Back in the 1990's we did a lot of business with Mill Log. We had a dozen or so sets of the smaller Twin Disc gear boxes. Back then we did our own overhauls on them and kept spare swing boxes that were partially assembled ready for the day when we had a failure. We would then finish assembling the gear box depending on what rotation we needed. That would get the boat back in service in a day or two. Most of them were bolted to Detroit 671s or 871s in log towing tugs.
