Deere 5020 Repowered With 8640 Engine

Deere 5020 Repowered with 8640 Engine ENGINES Engines 16-3-27 "When the engine in my 1967 Deere 5020 2-WD tractor wore out two years ago, I started shopping around for an engine to replace it," says Dennis Ricklefs, Palmer, Iowa. "I priced a new engine but found it would have cost almost $11,000. Finally I found a used Deere 8640 engine and paid only $2,800 for it. It works great. My 5020 was worth only $2,800 in trade-in value so for less than $6,000 I got a higher horsepower tractor. "At 250 hp, the new engine has almost twice as much power as the 5020 engine (130 hp). It's more durable than the old engine and has much more pulling power. It lets me use bigger equipment and saves a lot of time. I was able to switch from a 26-ft. field cultivator to a 30-ft., and from a 13-ft. chisel plow to a 17-ft. "Lots of farmers don't like this engine on 4-WD tractors, but I think the problem is that the engine is underpowered for big 4WD's so they turn up the fuel to get more power which damages the engine. I bought the engine used with 3,200 hours from a farmer who replaced his 8640 engine with an 8650 engine." Ricklefs had to use a bigger air cleaner and route it out the side rather than through the hood. He used the fan from a Deere 6030 engine and a shorter water pump pulley. He was able to use the radiator, starter, and generator off the old 5020 engine. The drive line bolted to the bell housing with no modifications.
