Default Re: Sony SL-F30 not unloading

I had a similar problem on the same model, yours may be similar.
It was a split in a small gear underneath the deck. The part is called ' Gear, small, loading'
If you remove the timing belt, (the toothed one), then undo the screws that hold the plastic moulding which holds planet gear assembly & the motor, you will be able to access it.
It's a small single cog, black, moulded on to the steel shaft that drives the gears on the top of the deck.
Once they split, the mech will try to load, but as extra strain is put on it, the cog slips on the shaft. It's p/no is 3-679-114-00, but they're like hens' teeth, so I doubt you'll find one.
I made a new one, using a nylon model gear bought on e-bay, which I modified. The cog o.d is 6mm, height; 7.5mm, with an internal bore of 2.5mm. It originally came moulded on to the shaft. The shaft is knurled, so with judicious use of a heat gun, you can fit a new cog on to the old shaft. I used a pillar drill to hold the shaft, and press it into the gear, whilst heating the shaft gently. I do have an exploded view, if it's any use.
Hope this might be of some use to you, or others.
