Figured I'd put this here for now so I can find it latter.

Disconnect the negative battery cable.

Remove the side panels.

Remove the tunnel cover.

Sand the drive shaft clean in the areas in front of the driveshaft output yoke and the cooling fan. Apply some sort of lubricant such as WD 40 to the driveshaft.

Remove the snap ring in the front recess of the cooling fan and slide it forward on the driveshaft.

While rotating the fan on the driveshaft, move the fan forward about 3 inches.

Put a jack under the rear end and raise the tractor about 3 inches. Put a block between the housing and the jack to distribute the weight.

Install a jack stand between the frame rails and up under the drive shaft, just forward of the driveshaft output yoke, the one that attaches to the rear rag joint.

Rotate the drive shaft so the spirol pin in the transmission input yoke is in the vertical position.

Lower the tractor, using the jack that you have under the rear, until the drive shaft is LIGHTLY! resting on the jack stand. The jack stand MUST be right in front of the driveshaft output yoke. The driveshaft Must be supported well enough that when you drive the spirol pins out you cause no damage to the transmission input bearing.

Now, drive the spirol pin out of the transmission input yoke.

Now drive the spirol pin from the driveshaft output yoke. You may have to raise, rotate, lower to get that pin in an accessible position.

Once both pins are out, raise the tractor with the jack, enough to remove the jack stand.

Rotate the yokes and rag joint assembly about the shaft and move it forward.

Be aware; if you have a single rear rag joint there will be a ball bearing inside the transmission input yoke that aids in driveshaft centering, do not loose this.

Remove the bolts that attach the driveshaft input yoke to the front rag joint.

Remove the driveshaft from the machine.

Replace the fan. Inspect and if needed replace the front rag joint, and the rear rag joint and both front and rear ball bushings.

cooling fan part # IH-547749-R1
rag joint part # 722-3000
ball bushing part #941-3004
5/16” x 1 ¼” coiled spring pins. Mcmaster-carr #91598A526


Put it back together.

Sorry, this is just from memory, and I been drinkin’, so use at your own risk!

Man, I love this rig for plowing snow! Power angle plow is the best, went through 15" of snow like nuthin'!

Chains on the rear make all the difference!

My k321 ran low on oil and stalled. How this happened is another story..(son).
I topped off the oil and now it just spits when trying to start.
Im thinking maybe the valve adjustments are the problem....not sure.
I checked for spark and there is plenty. Fuel is good flow.
Anyone have an idea what may be the issue? Thanks

Probably broke the connecting rod. Pull the head.

You can't run a motor without oil man. It didn't overheat, it blew up.

When you pulled the spark plug and cranked it over, did it have slight compression/suction when you tried to hold your thumb in the plug hole?
If so, it might be a stuck valve.
if not it prolly "done blowed up" as they say in nascar.
What ever happened, it is not good.
Operating rotating things without lubrication has disastrous and costly effects.
a scored cylinder & piston, galled connecting rod and crankshaft amoung other things.
if done @ operating speed, it most always results in a "window" in the side of the block which you can observe the carnage without disassembly of the engine.
Either way, the minimum is removing the head for inspection as Jon suggested.

Hmmm.... thats a drag. I think the guys are right, time to get into it. Maybe you should start a thread?

Power angle plow! I hate you!
