The CD tray on our RCD-970 would not feed after abuse from our 7-year old daughter yesterday. Took apart and found three of the cogs on the plastic cogwheel driving the tray broken. Took apart and glued the cogs back on with "superglue". The wheel is driven by the belt you mention. The belt was fine, though.

Getting the out the tray assy involved stripping down the player. No soldering required. Two of the scews are of "torx" type. The rest are "pozidrive". It can be challenging to recall where the screws go upon reassembly. Some 30 screws of 7-8 different types are involved. Labeling them and taking notes can be a good idea.

The player works fine now. Advice on getting Rotel replacement parts is appreciated.
