Needs help identifying part number

[DHB]

Hi,
Does anyone have an original copy of, or a reproduction copy of the parts list for a NH 68 square baler? I misplaced mine and it will be at least a week before I can get a new copy in the mail. The online version from New Holland does not answer my question.

Group 13 Item #57 lists the sprocket as part number 80163210 with 24 teeth, which jibe with the part I removed. The part I have has no part numbers listed. The part in PDF version from NH lists as a 12 tooth, and Messicks lists it as a 24 tooth with a note as being tooth (teeth?). I've been in contact with Walt's/Unger tractor and they said the 68 they have told me that the 68 they are dismantling does not have that number of teeth for that part.

I would have preferred to reuse the part I had. The bearings on the pickup locked up a few weeks ago and I had to grind, sawzall and split the sprockets off to get at this bearing. A previous owner at some point decided it would be a good idea to weld the sprocket on for some unknown reason.

This may not help but 80163210 should be used on these balers.

What size chain runs on this sprocket? If 2040 or 2050 chain the original sprocket may have been a 12 tooth sprocket but a 24 tooth will work skipping every other tooth. If number 40 or 50 chain it will use every tooth on 24 tooth sprocket. Hope this helps.

Messick's shows that sprocket as using 2040 chain which will work fine with the 12 tooth sprocket.
