2 Drive Belts and 1 Door Belt 421932601 for Sony 300 400 CDP-CX300 CDP-CX335 CDP-CX350 CDP-CX400 CDP-CX450 CX455 CD Player

The fact that I was able to not only find this product but then fix my mom’s 400 disc changer is just short of a miracle. Although installation wasn’t exactly easy due to the location within the machine, the thickness of them was helpful to roll on and get the machine working again.

These arrived quickly, if overpackaged (a tiny ziploc bag inside a letter-sized bubble mailer). Drive belts are square, and fit perfectly. Replaced both drive belts, as the originals had stretched way beyond useful length. Saving the door belt, as replacement isn't as simple, and door works fine. Player now working as good as new (left it on shuffle play for 8 hours). RECOMMENDED.

These belts fixed the problem, repaired one of my Sony 300 CD disk holders, turntable and door opener belts, will do the other one next week, very easy to install after watching an online repair video. Took advantage of having to remove all 300 CDs to clean each one and vac all the dust out of the unit.

The drive belts fit my Sony CDP-CX455 400 CD carousel perfectly. The drive belts turn to goo over time probably due to friction. Symptom is a whirring noise from the motors with no movement of the carousel. Replacement is straightforward but does require meticulousness. Remove the external cover, remove the screws securing the main board. Disconnect the cables from the main board so you can lift it up. Mark them or take pictures to facilitate correct re-connection. Then remove the white plastic shield This gives you reasonable access to the drive pulleys. The large pulleys are held in place by a single screw. Remove them and dig out the goo with a toothpick and clean with a cotton swab and isopropyl alcohol. The smaller pulleys on the motors are not removable. You must clean them in place. Do-able but not as easy as the large pulleys. Install the new belts and reassemble. The door belt did not need replacing. I think that is because it is used only to open and close the door which translates to much less mileage. Sorry, no video. But you can find several on the web. The videos on the web did not move the main board or shield like I did. But its MUCH easier if you do and not that difficult.

I ordered these replacements for my Sony 300 CD player that suddenly stopped working after 18 years. After watching a few YouTube tutorials I was able to replace the old worn out ones . These fit perfectly , now my player is like new.

These drive belts worked well in my SONY jukebox CD player. The installation is a bit tricky but if you take your time, it's worth it. I don't know how else to get these parts.

these belts replaced the ones on my Sony CDP-CX355 300CD MEGA changer, dirt cheap and the unit will probably run another 20 years.....

Ordered on a Friday. Came by USPS on Monday. Installed and tested. Turntable and CD loader work like new. Some claims were that the belts were thinner than the originals. My replacements seemed to be the same size and thickness as the originals. Highly recommended. Also, suggest watching a few of the installation videos on the internet.
