we have had a 963 since 85, only normal wear...mechanics say gearboxes are always out of oil when they bite the dust...so check the oil at least every week as the machine gets some age on it...we tried using 50W oil, but couldn't keep it in the boxes, went back to 85W140 with better success. we have found the main thing about these heads is to keep the roll knifes adjusted to where they almost touch each other...seems like it takes less power and feeds thru better.
