My friend Mike put a turbo on his 1964 4020. He runs his moco with it and it really worked the 4020 hard. So he found a M and W turbo off of a 7700 combine. He was hoping it would bolt right on and he could be rolling a couple days. Well it turned into a heck of a project and he almost abandoned it. The manifold off of the 7700 was like the one on a late 4020 so it was too tall to fit under his second hydraulic valve on the dash. Luckily he had the old parts 7520 that he bought. He took the triple hydraulic valves off of it and the console control out of the cab and put them on his 4020. Now he has a 1964 console 4020 powershift with a turbo. He mounted the hydraulic levers on the left side. Which some may think is weird but he has a loader on it in the winter and he likes to run his loader with his left hand and the shifter with his right. The factory levers were on the left side of the dash anyway. He is really glad the turbo worked out the tractor is performing amazingly. It uses less fuel and pulls the swather like a totally different tractor. We are really wanting to get it on a dyno and see what it is pulling. It does run a little warm when it is over 90 degrees out, but he said his radiator is in bad shape, so he is planning to replace it this winter. When I started cutting our cane it was about 65 degrees out so it was running good. I was cutting 7 foot tall cane in 7th gear and the pyro never got over 800 degrees. I was pulling a 12 foot disk mower conditioner. Before the turbo you couldn't get it past 4th gear. I wish I could have got some videos from that evening. Here are some pics of the turbo and the hydraulic valves.
He used the existing hoses to get rolling. That is why it looks like hose spaghetti on the back. He is going to replace them with short hoses that are the right length eventually.
Questions and comments welcome.
