Need a little help guys. Today I worked on removing the hydraulic lines from my 1973 140H3. Although I did my best to clean the dirt and grime off the lines before cracking them loose, I feel as though I still go some dirt in the lines. So before I re-install them, I want to clean the inside of the lines out somehow. I was thinking about trying to blow some mineral spirits through the lines with the air compressor, but I'm not sure if mineral spirits will break down the hydraulic fluid enough to get the lines clean. Any suggestions would be greatly appreciated, as hydraulics aren't my specialty. This 140 is a new adventure for me.
I bought the tractor a couple of years ago, which was basically the frame, hydraulics, and front axle with wheels. No motor, transmission, hood or supports, and no fender pan or seat. One of our fellow members hooked me up with a 1973 140H1 that is in better shape than my 140H3, so I'm converting all of the H3 hydraulics over to the H1. I completely stripped the H3 today of all of the parts that can be dismantled, so if anybody needs some 140 parts, let me know. I want to remove the fender pan of the H1 tractor tomorrow after we get home from church and pressure wash the transmission, so hopefully I can get all of the hydraulic lines installed, the rear PTO, and re-install the fender pan. I pulled the motor from the H1 due to low compression, so I want to pull the head and see what's going on inside. I also need to disassemble the carb, clean, and rebuild with a new kit.
I was going to completely disassemble the H1 and restore it, but since I'm planning on using this tractor for my garden work like plowing, cultivating, and rototilling, I think I'm just going to put it together and use it as is. Last thing I want to do is restore it and put it in the garage, afraid of scratching it, and having my wife get on me when I tell her I need another tractor for yard work purposes.
