44 A flywheel spacer/ oil slinger

I am to the point in my restoration to where I can install the flywheel. My question is regarding the flywheel spacer/ oil slinger. The one I currently have spins freely around the crankshaft. But my parts manual says nothing about the spacer being keyed with the flywheel. I'm assuming there should be one?.. also did john deere use V as a timing mark on the crankshaft gears? I just installed the crankshaft and timed it with the cam shaft but the only visual marking on the crankshaft gear was a V just wanted to make sure that was a timing mark
 
I assume you've installed a new cork type seal in the spacer. The spacer is keyed to the
flywheel. Flywheel has a pin that mesh's with the groove in the spacer. Yes V on Crank, Cam &
govenor gears are the timing marks

Yes i installed a new oil seal. My tractor is a hand start model. Will it still have the pin? Can you explain what exactly the pin is that you mentioned. When I removed the flywheel it didn't have a key or any sort of pin so that's kind of why I'm lost right now.
 
Look closely at the inside of the flywheel near the crank shaft splines. Yours maybe be broken
off, it happens. If you are unable to get the broken drive pin out, might have to drill a new Hole
for a new pin/key. They were someing close to 1/4 diameter. The slinger must turn with the
crankshaft or it won't last long.

Ok thank you for the info I'll take a close look tonight. Just to be clear it's not a woodruff key it's a pin or they had both? Because I can see the slot for a key.

Here's a photo of the oil slinger drive pin, D2009R.

The round part inserts into the machined face on the flywheel that butts up against the oil slinger, the square ''head'' enters the slot in the slinger.

The old pin will be sheared/worn off flush with the faced area, and you will have to drill it out, or possibly drill a small hole centered in the pin and thread in a self-tapping screw and attempt to pull it out with the screw.

You could try a small autobody slide hammer dent puller with a screw attached.
 
The pin is to make sure the spacer an flywheel turn together. It acts as an oil slinger and the inner face of the spacer is also the thrust
face against the main bearing.

ok I cleaned the flywheel uprealky good and I think I see where the pin broke off flush with the flywheel...out of curiosity why is there a key way machined into the flywheel? If that doesn't get used for the oil slinger

There should be a screw or pin (depending upon serial #) protruding from the crankshaft that mates with the extra keyway in the flywheel indexing them together.
Ok my serial number is 525486. I looked at my crankshaft and saw about maybe an 1/8 inch hole drilled into it. Would that be where the pin goes? I can't really make heads or tails of the parts manual picture of the flywheel parts. Just trying to make sure I have everything right especially on a chunk of iron rotating that fast.
