Here is how I disassemble the loading assembly for cleaning and re-greasing on this chassis.

Remove the four screws holding the front panel and the four screws holding the board assemblies:

Lift each board assembly up. The white holders can be turned to hold them open:

Carefully remove the clamper springs. They are easily damaged.

Gently push the catch in the back right slighter towards the power supply and pull the slider towards the front so the clamper can be pulled up and out.

Unscrew the grounding screw and remove wiring from harnesses:

Remove the two zip ties, unbend the holder and unplug the two connectors that lead to the loading assembly.

Push the right slider all the way forward and lift the loading assembly out of the player. Turn it over and you will see three gears with locking rings around them. Very carefully remove these locking rings and set them somewhere safe. I will not be disassembling the large cam gear on the right in this guide, but it is sometimes required.

Pull the gears up (don't worry about any timing). Clean the posts and inside of the gears. Regrease everything you are able to clean that has old grease on it with new grease. I use EM-30L.

Here is the goop that can hide under these gears that must be removed:

If you see any white grease on the loading motor gear (under the black plastic sheet), remove it all and do not replace it. If you have a new belt, replace it. If not, ensure the old one does not have any grease on it.

While everything is out of the player, clean off any other bad grease around the left and right sliders and replace it. I take this time to easily clean the spindle grip with a cotton swab and water and clean the part of the spindle that meets the clamper and apply a dot of grease to it.

Insert the loading assembly back in the player. Ensure this plastic piece goes back onto this screw:

Next, move the right slider one position back, but not all the way where the catch will engage. Insert the clamper, and move the slider back so the catch engages. Reattach the springs.

Remove the gear that is on the top of the loading assembly (again being careful with the locking ring), clean and regrease and put it back. Your timing should look like below:

Manually load and unload the player fully in each direction and ensure it all has been reassembled correctly before reattaching wiring to harnesses, etc.

Thanks for this tutorial cplusplus.

Been awhile since I worked on someone else's 3070 and I was already forgetting how I worked on it. This will be very useful when I get around to tackling the 3070 I acquired a few months back :thumbup:.

This has been so helpful. I recently cleaned and put new grease on my CLD-91. I managed to lose the roller that goes between the gear and the rack. It looks like I could use something else in its place, but I'm not sure exactly what. The part also doesn't seem to exist any longer (VNL1147). I'm curious if you have suggestions. I'm assuming the drawer won't work properly without it.

The player works. I haven't been able to get the drawer/loading timing completely right, even with photos. The mechanism started to work until I put the upper gear and gear holder assembly back on. That got me back to where I started. The drawer doesn't want to open.

I'll see if I can fish one out and measure it.

Thanks. I found it. It's so small it blended in. I'd set it on a metal piece in the player.

I've gotten the player to work, but there's kind of a snap when it opens and closes, so I think my timing is a little off. But it wouldn't open at all before, so this is huge.

Maybe this video can help (or maybe not).

This is a 3070 I worked on awhile back after I got the old grease removed.

Great write-up, cplusplus!

I have a CLD-91 coming in tomorrow that has the glued up gear issue.

A couple questions, at which step do you remove the tray? Are you able manually eject the tray, or does it come out as part of taking all of this apart?

This doesn't seem like an easy task, but with patience and paying attention to your steps, it will make things easier. I may reach out if I can't decipher something from the photos, mainly taking the slider assembly apart.
