Fabco 688-0684 is the 1/2-20 light pattern hex nut our parts manuals print as the PTO shift shaft nut. The books carry it at item 47, one per assembly, in the air operated PTO shift group of the Fabco TC 33 and TC 35, in the manual PTO shift group of the TC 35 and in the PTO parts group of the TC 33. The exploded views show it at the shift fork end of the shift shaft. It is a small part that is easy to mis-order, and the thread is the detail that matters: 1/2-20. A genuine Fabco part from Pro Gear and Transmission.
