Question QUESTION: I was driving on the highway near my home when I downshifted and heard and felt a "pop". Now the clutch pedal will not depress at all. I figure one of the mechanical linkages between the slave/pushrod and the lever arm pin has failed. I just wanted an expert's opinion before I pull the gearbox again.
ANSWER: Hi Tom,
Before removing the trans, you should remove the pinch bolt holding the slave cylinder in and pull it out to see if anything is wrong there first. If you can't find anything wrong there you do have to pull the gearbox since everything else is inside.

QUESTION: Transmission out. As I figured, the lever-arm pin was gone. The pin they sell is a too-narrow pin and a sleeve. Is this a good method of holding that in place, or should I run some kind of bolt or pin through the pivot hole? Another thing: I had a bad leak at both the front and rear seals after I put the gearbox oil in the last time I pulled the transmission. I refilled it with the front of the car jacked up, likely causing an overfill. The leak was terrible the first day I drove it, but there was almost no more after that first time. Would an overfill cause a temporary leak at both ends?
Answer Tom, you will have to refresh my memory as to what kind of Triumph this is and I am familiar with the tapered bolt that holds the fork to the shaft but I don't know what you are referring to as "pin & Sleeve". Who did you purchase it from and do you have the part numbers?
As far as oil leaks if you over fill the trans, you could experience more leaks than normal. However you also need to check the vent in the top of the trans to see that it is not stopped up thus causing pressure when the trans warms up.
