Dear Friends

This set was given to me by one of my friends. The only problem is with the dial cord. Both the pointers are controlled by a single knob.The shaft moves the flywheel and two clutches have been provided for the AM/FM bands. When the FM band is pressed the FM side clutch gets engaged and the AM band clutch gets disengaged thus providing movement to the FM pointer drive. Same is the case when the AM band is pressed. Here the FM clutch gets disengaged and the AM clutch gets engaged. My problem is that both the clutches are slipping. When the FM band is pressed the FM pointer does not move. When the AM band is pressed The pointer only moves 50% and again the clutch starts slipping. What is the correct way to adjust the clutch system? There is no jamming in the mechanical system.
I shall be grateful if somebody can help me in solving this problem.

Regards
P.Rajan
