I got a great offer for a new position as a field service mechanic for a oil and gas company here in the city. I don't start until January and I have been buying a few tools every week to spread out the expense. They will furnish me with a truck outfitted with service bed, auto crane, welder and torch but all the tools are on me. I was curious if any OSA members were field service mechanics that could think of any tools that one would not normally think of that have helped them in the field. I already have all the general mechanics tools such as sockets, wrenches, ratchets, impacts, ETC. I also have all the specialty tools that I can think of for my industry (water transfer pump units). Just wanted to see if any one on here wanted to give me a heads up on tools that have helped them out in the field away from a shop. Another question I have been rolling around in my head is how do field mechanics press bearings in the field. A large part of my job will be rebuilding centrifugal pumps in the field and the bearings are all pressed on to the impeller shaft. I have always had a large press at my disposal and never had to improvise. I know you can heat up the bearing in a oven or with a torch and usually slide it on but what about when you have one that has been in service for a year and is covered in rust and calcium from hard water and you cant get it off without a press or cutting it off. Thanks guys and gals!
