Yes Wallyworld should have Singer sewing machine oil or a brand from whatever machine they are selling. I bought my synthetic oil with the needle applicator at a hobby store that sold RC cars, planes, etc. They also usually have the silicone oil that you need for the cueing mechanisms. I thought it strange too, that VE had a service manual for the PL-117D, but no owners manual. Didn't look at it earlier for lubrication as I was just looking for clues about the suspension. Your right though all of those similar models should be the same in terms of maintenance. Usually the oiling point is marked. I have a Hitachi belt drive from that era that is very similar to the Pioneer that even with a new belt and lubrication still makes some noise between tracks from the mechanism. I sold it to a college student looking to get into vinyl for the first time and he doesn't hear it at all, but his system is very different than mine or yours or Wirenut's.
