John Deere Connecting Rod Reference

[StrikeForce]

I don't own every tractor manual and sometimes don't have the ones I do have with me. Is there a place in the John Deere world where I can get connecting rod measurement details? For example, I'd like to compare sizes of a AR86981 from a John Deere 329 diesel engine and AA2210R/A2344R from a John Deere A. I don't mind doing the leg work to find the information I am seeking but I haven't found any measurement details during online searches. Is there a reference site for something like this?

You may have to go to an engine spec book like a Federal Mogul shop Manuel. There may be others that have your info.

I come up with the AR86981 number being for the 404 engine? I have a 4020 service manual (JD) I could copy and send you if that might help.
email is open
Good luck

They may use the same part number between engines. I saw the reference to the John Deere 329 engine used in the 6600 combine in some historical threads on here. When I looked up the parts that was the same number used in the 4020. I am just trying to close the loop on some information shared on past threads.

Here is another past thread. I am just trying to understand where the commonalities exist that would allow these connecting rods to be used.

StrikeForce Found on Clevite catalog the rod dimensions for the 329 diesel. Don't know the length or pin size.

329 CID (5.4L) 6329T Turbocharged Diesel 6 Cyl 4.016in./102mm x 4.330in./110mm Rod Bearing(6) TM-112 CB-759AL STD,10,20,30 2.7480/2.7490 0.0015/0.0045 0.0750 2.9000/2.9010 1.1860
Journal size clearance thickness rod bore width

A2344R is a babbited rod but same as a 60 size. 1.7500 wrist pin. 13 inches length. Hope this helps. Lynn

321 CID (5.3L) 60 2 Cyl (1955) 5.500in./139.7mm x 6.750in./171.5mm 6 Rod Bearing(2) TM-77 CB-468P STD,20 2.9985/3.0000 0.0015/0.0046 0.0745 3.1500/3.1510 1.8500

StrikeForce Did some research and found the AR86981 came out of a 4020 Diesel and like machines. Lynn

Thanks! I am checking out that website and looking to see if I can glean any additional details. I think what I am looking at is the A has a 13" rod with a 3" crank pin while the 329/404 has a 9" rod with a 2.75" crank pin (that matches some numbers I have seen scattered about my searches).
