Default Replacing the draw cog and belt on CDM4/19 e.g. CD42/CD52

I thought I'd do a brief guide on changing this as a couple of people have asked me about it when I mentioned it in another thread. It's very easy to do and the gear and belt are available on Ebay at the time of writing for about 12GBP. The player shown is a Marantz CD52, but the CD42 is the same and probably the CD32 too.

Step One: Remove the four side screws on the case lid (Philips-drive screws)

Step Two: Remove the T10 Torx screw from rear of case lid

Step Three: Remove lid

Step Four: Fold back disc clamp flap

Step Five: Remove spring from flap

Default ...continued...

Step Six: Remove the 3 torx screws from the front panel

Step Seven: Unclip the front panel from the sides of the main chassis

Step Eight: Remove the torx screw from the underside of the chassis at the headphone socket end

Step Nine: With the player resting on its back, pull the face-plate slightly forward and carefully withdraw the tray. It doesn't need to be forced.

Step Ten: Return the player to its normal upright position

Step Eleven: Remove the old belt and tray/draw cog

Default ...final part.

Step Twelve: Check the part against the new one and insert the new cog after placing the belt around it and the motor pulley

Step Thirteen: Clean the lens with pure alcohol and a cotton swab whilst you're in there (if you've never done this before)

Step Fourteen: Reinsert tray, clip the front panel back on and put the lid and all screws back as you found them.

Done!

I hope this is useful.

Simon

Just replaced the cog and belt on my (20-ish year old) CD42 with parts bought off eBay for under 8 quid. Never done this type of repair before; the guide was really helpful - did it in under half an hour. Thank you!

Thanks Simon, I just fixed my 1992 Marantz CD42. It was easy, but only because of your comprehensive instructions.
