Plastic gears in this timer. after a while the cogs on the gears get worn until they do not mesh and the timer hangs up.
try shifting the timers time 12 hours. am becomes pm then change your timer pins to the same time but from am to pm or vice versa.
this gets you using another part of the main gear and the timer might work fine. if not you will need to replace the timer.
Check for badly worn chain allowing the mesh to get out of sync. Check that the chain is correctly adjusted as if it is too tight then variances in cog diameters overloads the chain and it will break. Check for correct cog alignment and check for bearing condition of the roller
This does happen with CD trays, it's quite common. I can't remember the exact mot common cause, but it's some worn out part, such as a small (plastic) cog wheel. Search on "cd tray won't open" on the internet to find a multitude of reasons, most to do with computer CD trays, but I guess the mechanism is essentially the same. These may also describe ways round the problem.
Some CD players have a small hole on the front near the tray into which poking a straightened out paperclip should enable you to open the tray by a few mm, enough to be able to pull it open in an emergency - but it's awkward to do on a frequent basis.
I had the same problem. The problem is to do with the little cog in the back of the helicopter that drives the tail rotor. If you reverse the helicopter it creates downward movement but if you fly forward it creates lift. This lift can actually cause the white plastic gear wheel to also lift and it looses contact with the drive cog itself. Undo the two screws to lift off the black casing, prize off the white plastic cog and file the underside down slightly. When you put it back in place it now sits slightly lower and does not lift too high when you fly the helicopter forward. Hope this helps.
These get stuck on everything with or without a disk. My advice is to take the cover off and see what it is hanging up on. It is almost never a motor. I would bet something is just off a bit that is causing the stick. There should be 4 to 6 screws to remove the cover and that will expose the drive itself. There will be a gear in there too that is usually white and plastic. That could be off the cog and just needs a tap to get it back on track.
If there is a disk in the tray that is not properly located this may be causing a jam - you may be able to get it open by carefully pushing something thin (like a credit card - or another disk ) in to the top of the tray slot to hold the disk down - take care not to push it all the way in!). At the same time prise the bottom of the tray VERY gently with a small screwdriver whilst pressing the eject/open button.
If that is not the cause of the problem the plastic cogs or the rubber drive belt that operate the tray mechanism may be worn / broken. Repair/ or replacement of these components is possible if you can locate the correct parts (try Ebay) but as CD or DVD players are so cheap to buy it may be simpler just to replace the whole unit.
More than likely the problem is with the drive wheels at the front. The cogs are most likely worn away - happened to me about 2 or 3 years ago and have the same problem again. Poorly made - cogs are plastic. You'd expect the cogs to be made of metal. Cannot order them from the States as Sears don't ship across the Atlantic. Have to try and get them in the UK.
are you sure it is the bearing ? normal deal is the cog wears like that from the chain running on it a bit loose over time the cog and clutch drive are a normally due to be changed every 2nd chain or every time the bar is changed also if it was the bearing if it is a 2 stroke motor the engine would not run because it would **** air into the crankcase
