He is sure it is rear feed. Is the light coming onIJ Belt tentioner can be misleeding for it can feel tight but it could be bottoming against anti swing back iron right at the pivot. Slip clutch usually has to sliped a thousand times before weakening. Does he have a 1"x1" bar fastened to rock doorIJ Does he have door locked half way open to form a sumpIJ I prefer the rock door fastened up in normal matter with the rock door hump kit fastened to it for best feeding and better rock portection than standard. Has he got third helical extended across top left corner of feeder openingIJ Has he got rear feed stripper installed for cornIJ Some people leave rear stripper out and run chain in fast speed for corn with added capacity and no problem with chain jumping a cog!!! Its very strang to have rear feed plugging unless there is something evident wrong. let us know what you find out.
