[Flathead Fever]

I rebuilt the cylinders on the aerial boom trucks at the phone company. It's an easy job except for getting the end of the cylinder unscrewed if you don't have the correct spanner wrench. We had a complete set of spanner wrenches at work which was really nice. A large pipe wrench will work but it kind up marks up the sides of the cap. If you take it apart and take the pieces to a cylinder rebuilder, they will match up the seals for you and then you can put it back together. Make sure the seals are facing the correct position when you slip them back on. Take a picture of them so you will remember which way the sealing lips face on the seals. Take the piston and cylinder with you so they can measure them to get the correct seals. They shouldn't charge very much for the seals if you take it apart and reassemble it.
