He Doubled The Power Of His IH 706

He Doubled The Power Of His IH 706 REPOWERED EQUIPMENT 31-4-29 A gas-powered, 65 hp 706 Farmall is a good tractor, but a 130 hp diesel-powered 706 is even better. Brian Tworkoski says converting a 706 to diesel power is a snap. All you need is a 400 Series International diesel engine and a clutch and flywheel to match. "Any of the International 400 series, the 414, the 436 or the 466 diesels, will fit the Farmall 700 or 800 series tractors," says Tworkoski. "I repowered a 706 about five years ago and then did a 766 two years ago. It was even easier to do as the engine fit the existing frame rails." The 706 was a little harder, but not much. Tworkoski had been thinking about swapping engines on it and had spent some time checking measurements. When the clutch went out on the 706, he decided it was time. He pulled out the original gas engine, replaced the stock frame rails, clutch and flywheel, and made a few more minor modifications. "I could have cut down the engine mounts to fit the existing frame rails, but I don't like to modify something that doesn't need to be modified," says Tworkoski. Instead, he bought Farmall 966/1066 frame rails from a salvage yard and bolted them right to the 706 housing. To reattach the narrow front end, he needed to add two small steel plates as spacers on the new wider rails. He also had to cut down the 1066 fan to fit the 706 hood, which he also had to extend by about 5 in. Everything needed to do the repower was available from Case IH dealers or from scrap dealers. The 1066 flywheel cost less than $300 from a scrap dealer, while having a new one made would have cost $1,400. "The stock 1066 flywheel and clutch fit right on the 706," says Tworkoski. "Hydraulic lines had to be extended, and the 1066 throttle linkage had to be trimmed a little. Even the stock 1066 starter fits right on." The used diesel cost him $2,000. With new and used parts, the total cost of the repowering came to less than $3,500. To Tworkoski, it was money well spent. "When you can take tractors that have been around for 35 years and still use them, it's foolish to go spend a bunch of money on new ones," says Tworkoski. "We can use it for anything, including running our ag bagger and a liquid manure pump. With the narrow front end, it's great for baling and spraying and as a chore tractor."
