Here are some pics of my 4020 and F145 3 bottom plow. The 4020 was just overhauled with a nos M&W engine kit and a new cam shaft. Tractor also has a M&W turbo. My machine shop raised the pistons height when boring the wrist pin bushings and set the valves to minimum specs. It runs great. It had very low hours on the last overhaul (before I owned it). The reason for this overhaul was when they installed the intake manifold one of the gaskets dropped out and when they reinstalled it they flipped it over. The holes still lined up but there was a small area about 3/8 inch where it could suck dirt and dust. Dad bought the tractor new in 1968. He sold it and I was able to buy it back a few years ago. Tom
