I have an M7060 that the Tension bolt was backed out too far and the two bottom nuts came off. It very difficult to even put the two bottom nuts on much less tighten them to prevent them from backing off again. Does anyone have a simple solution? The only thing I can see is removing the pulley to gain a little more access to the bottom of the bolt. I must say this is a very poor design. Hoping someone has done this before and can give me insight.
