I realised with an inner Thud that a couple years ago I misidentified the gear
on my Beta 25 (long story) as a TMC 60. It's actually a 40, as I realised last week after digging a little deeper. I don't have a really good excuse for making this mistake, so please don't ask
Anyway, for the last 400 engine
hours or so I've been chugging around with about 3x as much ATF in the gear
as it says in the spec. In the TwinDisc gear manual it does warn (in all caps, too) DO NOT OVERFILL. So I'm wondering what horrible things may have been happening inside the gear. It's been working perfectly, not a single
problem, so I'm a bit puzzled.
There was a little leakage, but not much really. Could the seal have suffered? The gear is a mite rattly in operation, but it always has been (since before the first oil change
where I made the mistake).
Anyway, when I extracted the old ATF it was definitely brown -- not black, not gooey, not full of metal, not emulsified, not weird-smelling, just brown. And it seemed to me it was almost the whole .6L, so there hasn't been a lot of leakage. I put in the right amount this time (shuffle, blush) ... though .2L seems like hardly anything at all... and am hoping I'll get away with having done something stupid.
Does anyone know what problems I should anticipate as a result, what to look for, etc?
