I have a 1939 212 diesel motor grader, D3400 engine, serial number 1R565, I rebuilt head, and I need precup orings and copper crush washers. I found these part numbers,
1A2298 oring
4B5647 copper crush washer
But can't verify bc I don't have parts diagram. Florin tractor has them, but I wanted to be sure before I ordered.
