CDM4 / starting to show trouble ejecting

Shike · 24th January 2011, 12:23 AM

Hey everyone,

I have a CDP with a CDM4. Recently the door has started showing problems not wanting to fully eject without human intervention. How should I go about fixing it? Is it just greasing the gears or are there other areas I should look at? Also, if it is the gears what grease would you recommend? Thanks.

Yes, I would say check the gears but also the small plastic pegs that slide in the tray side grooves. Would change the drawer drive belt also.
Good Luck.

Which model of CD player do you have? There are about four or five loader mechanisms that were used with CDM-4 based players, so what is likely wrong depends on the player.

If it is only struggling on the end of its stroke, then it's probably a worn drive belt. A worn drive gear usually results in difficulty and/or shuddering throughout the stroke.

I've got a tonne of spare parts for these players, if you let me know the model I can send you out a replacement part for the cost of postage.
