John Deere 45 Combine Part Identification

[TrenaryDucks]

I'm looking at buying an old John Deere 45 Combine. The owner said the bearing on the the reciprocating arm that drives the knife bar needs to be replaced. Attached is a picture of the arm with the missing bearing. What is this bearing called, and any ideas as to the part number? Also, any ideas of where to get a replacement? Thank you.

You can look it up at jdparts.deere.com (might have to look under equipment search to find it "Combine")
The missing bearing housing is PK1647H
and the bearing is JD 7143C
BUT,when you check the availability it can't be found,so you will have to ask a dealer?
That is the sickle pitman bearing.

Thank you for the quick and detailed reply.

PK1647H shows to be available in Tennessee from Parts Depot but one has to go through a participating dealer to order the part. Brg is available from JD JD7143 Ball Bearing - SINGLE ROW BEARING PNL ADD 25.86 USD if part number is entered correctly.
