Looking at the picture it looks like a sprocket/ pulley and belt/ or chain on the unloading auger tube?? Never seen one like that.
Great looking combine , make sure you change out the primary countershaft bearings , Venezuala is a long way to wait for parts lol

New decals, green cab top, HP was increased, Cleaning shoe was increased, feeder house reverser now standard, and a few other improvements. Why they was called the Titan IIs. Just an improved version.
Today JD has gotten away with that. Now they add a few modifications and call it a whole new series.
The Titan II has a bigger clean grain elevator, tails elevator, more air to the sieves, faster cleaning shoe, straw chopper is heaver that hold the blades, the heaver rear axle, rear wheel drive, dail-a-matic for the head.
Nice 7720. I like those rice tires on it. They should be helpful in the mud.
The primary countershaft runs from the engine flywheel to the large set of pulleys on the left side of the combine. Lift or take the seat out of the cab and lift up the tin panel to see it all. That shaft on our 8820 broke right next to the pulley set and was a heck of a job to replace. We had broken the secondary countershaft the year before(also a big job). It takes some mechanical ability and lotza patience to work on combines and I wouldn't recommend it to everybody. Get help with it to familiarize yourself with the machine.
