Among this batch of machines
A new batch just arrived
from back in May was a Kenmore 117-95. Except for two Red Eyes, all the other machines are serviced or gone. I was sitting on the motor for this machine for weeks, not sure as to lubrication. By way of distraction, I have a Kenmore Model 52 (158 series) up next, and the motor on it wouldn't turn at all and has a sticker on it about oiling it with a couple of drops every 6 months. The motor casing on the 117-95 has substantial wicking material in each end, but a very small opening for lubricating from the outside. I wondered if it should be oiled (I don't have a manual to check, and didn't look) but was very uncomfortable with doing that as most motors are greased, not oiled.
I ended up melting petroleum jelly in a closed, clear container on a black surface in the hot August sun, then injecting the liquified petroleum jelly into the wicks before reassembly. The petroleum jelly solidifies very quickly once out of the sun and out of the container. I'm still unsure about having done it this way.
The other thing I am wondering about with this machine is how it differs from a Kenmore 117-959
"New" freebie Kenmore 117-959
I wish I still had the 959 for a side by side comparison. I like the 95 more, at least the color anyway. It sews very strongly, and I happen to have an empty Kenmore cut table to hold it.
