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

[SimontY]

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

[SimontY]

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

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.

thanks Man!! I just fixed my cd52. I took the gear from a magnavox CD610. I will replace that one later.

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!

One question. What is the dimension of the belt?
