We have a 8550S Hesston with a 8070 15 foot header. We have a problem keeping bearings in the helper roller on the crimper. I read on a post some time ago that someone took out the helper roller and put a plate across behind the turtles. If anyone out there has done this it would be much appreciated to know how the machine worked after this modification and how wide a plate you need to put in there. It would be great to here from someone soon, Thankyou
