yup, had a few of these. After one of these bends it eats the bushings and will unless you get them straight. lay a long straight edge on the sheave edges to determine the angle it needs to be bent back to. We then drive a fork lift mast up flush with and touching the throat in front of the feeder beater, hook a chain around the pulley, carefull not to bend the sprocket and after locating the chain at the proper angle, tilt the mast back, thus tightening the chain and bending the housing back to square - have to go past as it will have a little spring back. Checking with the straight edge it should now be parallel to the side fore and aft and plumb verticle. Then replace bushings - we drill and tap and install a grease hose to allow greasing in the future. In rare cases where the stub shafts that hold the bushing are egg shape and the stubs are rough, we have a thin steel bushing cut to drive on the stub and have the hollow shaft brass bushing cut to accept the now larger diameter pivot stub or stubs if you do boths sides. Be sure to remember these are eccentric hub_shafts on the left and right and rotating them will result in different tilts side to side of the throat. We usually like for the lh to be higher than the RH (viewing from the rear) Finally the torque sensor, if grabbing_slipping will cause the pivot drive belt to snatch,slip and grab and will bend the pivot shaft. MAke sure the main clutch shaft sheave grease zerk is open and lubing the shaft as it must do to allow the torgue sensing to work properly.
