Cd player tray shudder. Any ideas?

[crispynz1]

My cdp tray has a shudder, which is violent enough to make a disc jump, when the tray is near to full extension. Would this be caused by the cogs becoming dry? Would a bit of Vaseline do the trick? If not, what's the best lube to use? Thank you.

try and use a fine non hardening grease like castrol brake grease

only lube very lightly so as not to put too much resistance on the sliders or cogs

Also check that no gunge or 'crap' has become stuck on the gear travel path at the back of the tray, and that the tray drive gear is intact.

FWIW Had a similar problem with a Philips CDP.. the tray drive gear had started to disintegrate :eek:

Oh yes, I've had the ol drive gear teeth disintegration problem with a CDM Philips drive.

 

Hopefully it's just a lube issue... there's often a bit of orig residual grease on the sliders etc that you might be able to employ.

I've found Margarine to be an excellent lubricant for Cd drawer mechs. I havent noticed any sonic differences betwwen Meadowlea and Flora Pro Activ lite though.

Smells like teen spirit, however?

Seriously tho'..have you considered vegemite or marmite??.. or can't tell the difference...?? blends in better aesthetically with black CD trays

 

To get back on topic,

 

Christian,

 

the trouble with vaseline is that it hardens when cold and so not so good. A touch of silicone grease was probably used when built.. at a guess....

[bluedog]

silicon spray the only way to go use food grade :-)

Rubber Grease. I think this may be the same as brake grease as we use it on Rubber Brake Cups etc. Doesnt seem to harden.

Or Lithium grease. Take your pick.

 

Whatever you use, use it sparingly. Should just be a light coating.

 

Cheers, Shane.

Thanks for the tips. There appeared to be no damage to the cogs, just a little fluff. A light coat of liquid Teflon on the sliders/rails has removed the shudder.
