The VHS side of this unit stopped working and when I inspected it I notice the Cam Gear ( i assume that's the name) that the worm gear drives for ejecting has broken. Instead of a solid wheels it has 6 or so small plastic spokes that all of which broke. This cam gear appears to be riveted to the vhs carriage so I would imagine I would have to replace the carriage. Where would I begin to order a replacement gear and/or carriage to make this unit operational?
I know sony has an option to ship the unit back (out of warranty) for the charge of $114 and they would fix it. It just seems outrageous to spend $114 to replace a $0.50 piece of plastic that had an apparent design flaw.

Something must be broken if the motor is turning and the planetary is not. It will be one of the following, we will start from the first point of contact with the armature
1) Worm gear broken (fuse gear) you say no teeth broken
2) Worm gear not broken but whole unbroken plastic part not gripping aluminium boss
3) Pin through worm gear broken or missing
4) Pin through centre (or bevel) gear broken or missing
5) Pin through small gear in planetary broken or missing
6) Pin through planetary hub centre shaft broken or missing
The most common ones in order of likelihood are, 1, 2, 3 and 6
to open the reel and access the worm gear cog ( the gear that actually drives the level wind ) you will need to remove the handle, the star drag assembly, the side plate screws etc. Before you do all of that look directly at the front of the reel beneath the level wind face plate is the worm gear pawl ( the tooth that actually rides in the level wind gear itself ) there is a cap with a flat head screw driver slot in it, remove the cap ( if you can access it with the face plate on other wise youll have to go thru the steps previously mentioned) and carefully tap the reel until the pawl itself falls out there will also be a very small washer that goes inside the cap. Inspect the pawl for defects like chips on the points that ride in the gear. also inspect the worm gear it self, debris that gets lodged in the gear from regular use can chip the ends off of the pawl which will cause the pawl to stick to one side or in extreme cases stop working all together. It is possible that the worm gear cog ( located in side the reel ) is damaged but almost every reel with this issue that I have repaired (100's of them) is caused by a damaged pawl or worm gear it self Dark Side Reelz
Jeff your almost there....it must be the shifter into third....it must not slide fully into third....check for wear marks on the worm gear....and try running it without the protective cover on to see how it changes from 1st, into 2nd, then third...that mechanisim if not engaging totally in third.
they should be a tight fit as the clip is just to help retain position
if they are ment to be loose replace the clip and inspect the groove for the clip as the edges may be worn to a taper rather than a sharp edge which will allow it to be moved out under load
Don't worry about the Worm Gear for now. You have to make sure that the Motor
is fully functional by itself: Remove the Transmission Housing Cover (4 screws) and
the two screws holding the Motor down. Lift the Motor off the Worm Gear and set it
on the side (be careful of AC voltages from the Motor and Control Assembly).
Select Stir setting and observe the motor shaft. Is the Motor running? If it is,
Select other speeds to see how the motor performs.
With the motor now fully functional, you can now check the Worm Gear Follower
for worn out/broken teeth. Remember the motor drives the Worm Gear, it then in
turn drives the Worm Gear Follower (you may have to remove the grease to see it)
The Bevel Gear sits right on top of the Follower and drives the Attachment Gear.
I belieive i"ve found what you need at -the gourmet depot.net-click on worm gears on the list on left side of page,parts with pictures and listings will come up.I think you will want the kp50 series 5 parts
It sounds like you have lost some teeth from your worm gear. This usually happens when the mixer has been overloaded. The teeth on the worm gear are designed to fail first to prevent more serious damage. To replace the part you will need to open the head on your mixer. The gears are at the front of the mixer packed in grease. It should be obvious that the worm gear has broken once the head is open. If it is not the worm gear, with the head open it should be easy to spot the problem. The gears are available as spare parts from several places on the internet. search for "kitchenaid worm gear"

When you replace the worm gear, you should be able to see if you need more grease. This will have been the "oil" you saw escaping.
I picked one up in the trash 2004 model 27MDTR20/17. I turn it on and it shuts off. I opened the back and pulled the DVD/VHS board out. I removed a metal cover on the VHS housing (three screws). There was a broken clear plastic rod and one of the gear stop plastic cords (on the left side) was ripped where it attached to the front metal bracket through a hole in the plastic tab. The plastic chord has a piece of white felt like material attached to it. I epoxied the plastic rod back and put a piece of tape over the broken plastic end of the cord. The tape was folded over the edge of the plastic and then wrapped back on itself. I trimmed the outline with a scissor and poked a new hole in the end where the original hole was under the tape. I attached the chord back to the metal bracket. The problem was still there, the power would go off after a few seconds and the VHS gear train would make a slight motion like it was getting stuck. I then removed the mounting screws on the VHS housing and lifted it off the board slightly (ther are 2 screws that need to be removed from the far side also). There is a small gear under the right side of the board that was not aligned with another gear. The alignment is between a pin on one gear and a hole on the other. After I aligned them I reassembled the unit. The power stays on now only if I leave a tape in it but the DVD and VHS seem to work. My problem now is that I can only select AUX and channel 2! On well thats my next battle. Good luck.
I'm guessing the "black thing in side" is referring to the actual tape itself- ribbon like which can be spooled out of the tape case.
If so, then your VCR may have a mechanical problem of some sort, which results in a "no tape transport" or "no tape takeup" problem. If the latter, the right reel (takeup reel) is not being driven. Older VCRs often used a small rubber rimmed drive mechanism to drive this reel. Newer VCRs (10 years old or less) pretty much use a gear drive. Something may be broken here, or perhaps the gear is stuck. This gear assembly has to swivel back and forth, from left for rewind, to right for takeup or fast-forward. Unfortunately, you can't see the gear once the tape is in the machine, at least not from the topside.
Suggestion: Take the top cover of VCR off, look for this gear, and see if it swivels freely, look for broken gear teeth.
