I have never experienced it on my own combine, but I am a service tech at a NH dealer, these are some of the things I have seen.

TR's - Torque sensor snap ring fails crating a fire hazzard and possible frame damage.

- Upper returns bearing fails and lights up the chaff under the cab

- fuel lines leaking, ignited due to the exhasut manifold

- front rotor bearings

- shorted electrical in the lighting harness

TX's - shorted electrical

- intermediate shaft bearings

the only modifications that I recomend is for the torque sensors on TR's. Take the snap ring off, then get a machinist to cut threads in the end of the hub to match a large wheel bearing nut. Also have him torque the nut on to about 400 ft.lbs, and have him drill a hole for a set screw, the hole should go right into the hub. Reasseble the tourque sensor, put a drop of red loctite on the threads of the nut and torque it down until the set screw holes line up. Tighten the set screw.
