Let's clear the air here...you did not 'piss me off'. You just added more complications to her problem that weren't necessary, as did JW. But I'm used to that
I used to train technicians at Maytag on the Whirlpool products back in 1994-1997 when they were beginning their campaign on all-brand service. I was originally a Sears technician starting in 1974, and worked exclusively on Whirlpool prducts and we were trained at the Sears Technical Institute in Dallas. At one time, they actually had a college for this stuff, although it is gone now.
Back to the problem at hand. If the upper seal leaks (brake tube, agitator shaft), there will be oily brake pads and the ring around the wall of the cabinet. This is due to the leaking water which has displaced the oil in the transmission. You always replace the gearcase, clutch and spin tube if this occurs. On the other hand, small amounts of oil normally migrate out of the top of the transmission during operation just because they do not seal the tranny. The little washer that goes under the clutch is there to help contain splashing oil from the shaft area. If they sealed the transmission off, pressure would build up inside with the action of the multiple gears spinning around and would cause other problems, so they intentionally leave a small gap there.
Seeing traces of oil inside the clutch is not necessarily a sign the upper seal is involved, that's all. It happens quite a bit and is harmless. Seeing an oil ring like the pics above would lead to a major overhaul instead. I guess what provoked me the most was guys adding other factors to a seemingly straightforward repair, thus confusing the poster and maybe leading her to buy the spin tube instead of what she should have bought in the first place. The repair guy in her town was absolutely no help, selling her a spin tube without selling her the spanner wrench to remove it.
The only thing I would like to see differently on this forum is when I give someone a prognosis, unless I am completely off-base, there should be nobody else chiming in to complicate what should be a simple procedure. After all, average consumers have no idea what they are looking for in the first place unless we instruct them, so we don't want to fill their minds with details that may or may not apply to their predicament. I will not be offering any more advice unless asked.
