TheTurtle Posted December 25, 2016 Report Posted December 25, 2016 Theoretically... If someone were to swap tachs, do you grease the cable? I heard it looks like there was some kind of goo in there. There was talk of a guy unscrewing the cable from the back of the tach and the inner cable with the square end didnt want to come out without some force. Is that normal? While fiddling with the back of the tach what would happen if you pulled to hard and the cable came undone from the motor side. Maybe unscrew the sheath from the motor side and stick the inner cable back in? Possibly theres a key way on the motor end and it only goes one way? I thought I had heard something about cables being to long and destroying a tach? What would cause that? How would you know if its to long? Quote
carusoam Posted December 25, 2016 Report Posted December 25, 2016 Look at the back of the tach. It has an oil cup that gets filled on a schedule. Like at annual... It's construction is similar to a bicycle's speedometer. Expect that the cable is worn if it hasn't been changed in thousands of hours. If the tach is bouncing around, that is a good sign of wear. Or the cable isn't routed and supported properly... the cable probably unscrews at both ends using your fingers. I don't recall using tools. It has been years and my memory is fuzzy enough...
