Earnest, what are you using for output shaft
bearings? As I reported last year the oil seal came out on the out
put shaft of my Marcotte gear box. Two Eaton gear box engineers are
working on a solution to circulate oil to bearings and also cool the
oil. The output shaft has two tapered bearings with the small end of the
taper facing each other and the consensus is that the oil will always move from
the small to the large end of the taper, which will trap the hot oil next to the
seal. There was no return for the oil or a retainer for the
seal. These bearings were totally submerged in 80W oil. If this is
indeed the issue the case expanded and the seal fell out. JohnD
