outpost22 Posted July 19, 2008 Posted July 19, 2008 Been reading about "chocolate" gear oil too much lately and decided to drain and check the 'ol '96 RT tranny after running 5500 miles on Mobil1 75w/140 synthetic. (The bike has 55,000 miles on the odo) Bike has been running and shifting flawlessly (knock wood). The first picture shows the oil color drained into a mason jar with a spot of the old oil next to it on the white paper. The spot on the bottom of the picture is new oil for comparison. The oldoil appears to be darker than when new, yet I don't think I could call it chocolate. The drain plug had virtually no metal on it at all except for the usually light "smudge" of mush. I know the older trannys are reknown for the shift fork issues, but I could not see any non-ferous particles floating in the oil, although I'm sure that doesn't mean much. The second pic is the old oil held up to the sunlight Opinions?
SageRider Posted July 19, 2008 Posted July 19, 2008 No "milk chocolate" apparent to me. It is very obvious, looking almost like what emulsified water in the oil would look like, only smoother.
smiller Posted July 19, 2008 Posted July 19, 2008 I would agree with Michael in that at first glance it doesn't look like the classic 'chocolate gear oil' color, or at least as much as one can tell from a picture. Plus the problem associated with the chocolate gear oil symptom has more to do the the M97 model transmission. If you are concerned you might send in a sample to Blackstone for analysis. $20 for some peace of mind.
outpost22 Posted July 20, 2008 Author Posted July 20, 2008 Thanks for the input. I think the oil looks fine too. When it was draining, it looked like a nice amber color. It was when it was poured in the mason jar that it looked "dark", but not milky. Thanks, Mike
