John Deere AN project

Cleaned up the oil pump and installed the screen. Need to clean out the crankcase before the pump goes back in.

Oil pump looks good. That was pretty dirty.

The crankcase cleaned up faster than I thought it would. My other JD A took hours to clean up. Looks like its ready to start going back together.

Thanks for sharing the photos. All that heavy iron is amazing!

Dropped the oil pump out, removed the screen, and cleaned it up. I think I'll open up the pump tomorrow and see how it looks. Might as well do it while I'm right there.

That looks a whole lot better!
The before looked like having to suck a milkshake through a straw with mud stuck in the end!

Installed the bearing retainer/cover on the first reduction gear shaft and safety wire. Then the oil pump and hooked up the oil lines. I applied some RTV to the gaskets that I was able to reuse. Gotta wait for some help with the crankshaft install.

That looks a lot better! Nice and clean like it should be!

Looking good! How much does the crank weigh?

I have no idea myself, but I can guarantee it's HEAVY!

I'll weigh the old one and let you know.

My brother stopped by and started cracking the whip. After a good clean up of the crank and main bearing housings he helped me load the crankshaft back in the tractor. Now I need to torque and check the rod and main clearances.

 

[Mark 149 J.]

He's good at cracking that whip!

Cjet, I'm not even into Johnny Poppers, but this thread makes me want one!

Be careful. Its hard to stop at just one.

Just weighed the old crank, 84.4 pounds. Not as heavy as I was expecting. I guess it feels a lot heavier when your trying to wrestle it through the side of the crankcase, that and I'm not as young as I used to be.

I'm surprised. I was guessing it would be 100 pounds or better. It would seem a lot heavier in this application... not like lifting something straight up. I know what you're saying about that "not as young as I used to be" stuff!!!

Had a few rain showers passing thru so instead of taking the tarp off the tractor I did some clean up on the first reduction cover. I had to boil the clutch dust shield in some tri-sodium phosphate, simple green, and oxy-clean to get the sludge out of it. I'm thinking I should paint it now while its off and easy to get at.

Be happy you got a AN, I think a 80, 820 and 830 crank are over 100 pounds.

I put the first reduction cover in the blast cabinet for a quick cleanup. After blasting I treated with Ospho (phosphoric acid). I'll let it dry overnight and then spray it with epoxy primer.

Wow! That looks really nice!!
