Pulling the A-B cam from a Rockola 437

Apparently the little intersection where the follower switches from A side to B side is boogered up. Do I have to pull the entire mech to pull the cam?

Eddie: I was able to free mine up by liberally oiling with 20-weight while rotating the drum by hand with the motor disengaged. IF yours is the same as what's on the 442, the dog is clipped to a piece that's bolted in place by two screws and has the spring-loaded linkage connected to it. You may be able see how it's fastened looking through the back and front doors.

It's close to the same if not identical. I think I may see the problem, but not sure how to fix it easily. the linkage is rubbing the motor. It has always worked and appears it has rubbed for a while. I am thinking the place where the alternating dog switches grooves may be damaged, but it is so hard to see up in there.

Eddie,
I have always been able to free them up, using 20 wt. oil too, followed by graphite grease--however one "caution"--IF--your phono has an external switch located on the bottom of the read-out side, that stops the motor if no pins are "pulled", do NOT "work" the basket backwards, unless you first remove that switch (do not axk what happens, iffin you don't do this !!) Also--watch the "fingers" on the read-out arm, if reversing it. Ron Rich

I'm going in...armed with an oil can...

Eddie: from your post I am not sure if the basket is jammed or if when scanning it does not flip from A to B. If it is jammed I agree with Ron. if it is a matter of not swapping between A-B then you can try to get the dog to go deeper in the cam groove. the arm it is attached to can be gently bent to get it in deeper to where you can get non-worn cam groove as it is made of aluminum.

The initial problem was the unit would not play B side. When you rotated the record drum, you could see it try to shift, but it didn't. I wrote a prior response but apparently I didn't submit it. I like to respond to post until completion so others may benefit. I removed the motor.... I could see the divider between the A and B slots was bent where is makes the transition. I straightened it, but it still won't transfer correctly. The little follower is free and clean and the slots are clean. I need for someone to verify which side of the bracket the swivel point is mounted. This one was mounted on the inside. Drawing seems to show it on the outside but is not clear. This may have caused the arm to rub the motor and the follower to be partially engaged in the slot. Can someone verify?

follow up... I think the core problem was the bracket was bent just a little as suggested. I bent it toward the record drum and straightened the bent end on the cam slot separator. Bending the bracket got it off the motor and further engaged the follower in the slots. The arm can only go on the inside of the bracket. A shoulder bolt is used and if you turned it the other way it would sho nuff rub the motor. So glad I didn't have to pull the mechanism. Thanks for the help.
