Squeaky Capstan on my Sansui D-X311WR

[patricklm]

Hi all, I have an old (1990?) Sansui D-X311WR Dual Cassette Deck. Speed and everything is fine but I’m getting a squeak when playing the right deck. I have the top off and I can head it when I rotate the large capstan wheel from behind. No squeaks on RW or FF. Anyway to easily lubricate this? I say easy because the left deck is working fine and I’m not playing on duplicating anything right now but I have the case open. Thanks!

Here is the parts breakdown of the cassette mechanism.

1. If you can get to it, put a tiny drop of synthetic oil at points 1 & 3, the capstan bearing. Don't get oil on the capstan shaft, else it will spread and get on the shaft and tape. The bearing is probably brass and it is best to lay the deck on its back when you apply the oil so it will run into the bearing.
2. If that doesn't work, check the pinch roller bearings (2 & 4) to see it that if what is squeaking. If you oil, don't get it on the rubber... only a tiny bit. Sometimes the pinch rollers use nylon hubs vs brass in which case it probably does not need oil.
3. Use a toothpick to put the smallest droplet of oil, then touch it to the bearing.

Thanks! Exactly what I was looking for.
