The crankshaft thrust bearing in this 4-cylinder version of the 301 is the same exact thrust bearing as a 180-185-190-190XT-200-7000. We never had any issues with them. This tractors foot clutch is a flywheel/clutch disc/pressure plate from one of those bigger tractors shoved into the smaller D-17 bell housing. The 6000 series had foot clutch pressure PLUS PTO clutch pressure, which at times, was just too much for the thrust bearing.

Dumb question...but I have to ask. I assume there really isn't an issue with the engine thrust bearing given the difference between the D17 setup and the 6000 series tractors with their PTO clutch, correct? Only time thrust bearing in this engine would see any thrust from a clutch is just when the clutch pedal is pressed so it's only for short periods of time.

At the 15 second mark is where I threw it into the high side. I did all the other plowing in low 2nd. I was afraid if I hit a rock at nearly 6 mph the plow might suffer severe damage.

Djo220, thanks for posting the video. DrAllis, After the dog got out of your furrow, I thought I could hear that you power-directed it into Hi? The plow sure makes the 433I talk it up - great sound! Interesting combo.

It will seldom get used plowing again, and only for show if it does. The old gas engine developed 210 ft lbs of torque at 1,000 RPM. This turbo-diesel engine develops 240 ft lbs @ 1400 RPM, so 15% or so more torque, but at a higher RPM, which is good for gears, bearings and shafts. I figure if the tractor is never weighted down more than 6,300 lbs and the engine is operated under heavy load at 2,000 RPM or more, no harm will ever come to the driveline.

The engine is from an F-2 diesel combine, transplanted into a D-17 gas chassis. The only sheet metal alteration was opening up the air cleaner hole about 1/4" for the larger air cleaner inlet.

Actual dyno test was 85 HP @ 2300 RPM's. Slowing the engine down to 1650 (PTO speed for a D-17) it still has 67 HP and stays on top of the turbo down to 1400 RPM.
