That does suck; but I am glad it got caught before real damage was done. Please update us on the cause.

well here is the story of the cause of the metal. when my brother and i redid the top end from the piston melt down. we thought that we had gotten all of the metal out of the crank case. for which I am sure that we did. But the part that we failed to remember from our newness to the way the motor and trany are built we forgot about the oil being shared. so i don't know that a person could ever do a very good job getting it all out of the motor. so lesson learned some types of top end rebuilds should only be done by a shop that knows how and has all proper tools to do the strip down and cleaning. since a melted piston makes a mess. i should of let the mechanic do it the first time. al well i learned my lesson. and now he is doing it so the job will be done right.
Well at least your learned from this and can pass it on to another owner. I am also one that feels at times you just need to get the professionals to do some jobs
Something a bit strange in this or I'm out of touch.
I've never worked on an oil in frame Triumph but I figured they are similar to the oil in tank 1970. You have oil in 4 different places. The primary drive case that also contains the clutch, this oil is contained. The gearbox, also contained. The other two places do naturally mix, they are the oil held in the frame and the small collection in the crank before it's pumped back to the frame. Check this vid.

I just spoke to a mate who's had a few T140's apart.
I'm correct no practical difference to those that I've worked on.

Not so, you're having your chain pulled.

Otherwise is correct. In fact, the transmission uses a heavier weight (gear) oil than does the crankcase/frame.
Kevin and AJ are spot on. The tranny and engine do not share oil, at least with the 650's.
Thaks for passing this on. Good information.
