My bet it the reverser was hot because the belt was slipping. The belt was slipping becuase it was not correctly tensioned. Read in the operator manuel the correct tensioning process. The idler pulley adjustment is not what determines the belt tension. This is going by memory for me as I used to own a JD 9670 but now have the s series with the 5 speed feederhouse.
I know from experience that a chopping corn head doesn't allow for the belt to be poorly tensioned!!
Did you put in synthetic oil in the reverser? It is a good idea but if you change often, regularly, (yearly??) 80-90 GL5 could be OK.
Good luck, Jim J
We tension the belt using the upper pulleys and not the idler as per the manual. Learned that back on the 9500. We changed the oil in the reverser when we got the machine 2 years ago and we only use synthetic in all the combine gearboxes. The belt was definitely getting hot but the slop in the pulleys was apparently the problem. Once we changed them we're back running much cooler. I don't know what the two previous owners did as far as greasing on the reverser sheaves. Thanks. |
