Remove nut and washer under stub shaft. You will likely find that washer is bottoming before holding parts in compression. This could be from nut starting out loose which will allow hub to erode away into inner bearing race. If hub is eroded the parts will not be in compression even if nut is torqued thus shaft will flex and fail. You need this stuff in compression to build a solid assembly. Also tear down torque senser to see it isn't scored up from lack of grease. If these torque sensers are not greased adaqately at predelivery it may be a year or two of normal greasing before grease gets to where it needs to be. The zirk on stub shaft is most important for once it fills the cavities with grease it will spill onto the jaws. This takes a good 100 pumps of grease to fill voids before grease gets to where it needs to to do its job. It is also a good idea to cycle this varible from time to time when not running in corn. Do this at idle especially if you have air reel. Fan will explode if subjected to to much RPM. Customer found this out the hard way on a brand new header.

We have also found one torque cam 'crowns' with a ridge from running in same spot - just enough to notice. We took the cams and polished with a scotch brite high speed buffer and solved a problem on an older machine here as well as on other torque sensing drives elsewhere. If these are not really smooth they will not actuate as well and sometime slip and grab - thus transmitting a shock load.
