The 5050 capstan motors require oil on the upper bearings. Remove the pinch roller (keep track of any "spacing" washers that may be installed above or below the roller's center!). Unscrew the round ring that surrounds the capstan shaft itself. Beneath you will see a sort of "foam rubber" ring, and here is where you apply a FEW drops of oil on a semi-regular basis.

From the Ampex/Recordist website:

"Many Ampex manuals specify Gulf OC-11 oil, or turbine oil, for lubricating capstan and motor bearings. This oil is available from Ace Hardware. They sometimes call it "zoom spout oil." The Ace Hardware SKU is 12054; the UPC is 650760236548 (012054)."

I haven't checked recently with my local Westlake/Ace to verify, but they DID stock that at one time, and it seems fine to use with Otari machines based on my experience.
