How do I oil the motor on a C&P?

I purchased a new style C&P, and I believe the motor needs some oiling from the squeaky noise it’s creating. How would i go about that? And what oil should I use?

Any help would be appreciated!

Trying to post images of the motor, but it’s not attaching for whatever reason.

Assuming the motor doesn’t have “grease cups”-

Depends on the age of the motor (how many C&P’s have original motors? probably a bunch). A non-sealed-bearing motor usually needs “electric motor oil” :), usually it’s about 20-weight lubricating oil; I usually get the 3-in-one EMO, which should be available at better hardware stores (or online, of course).

Do not use engine oil and do not use light-weight oils like turbine/sewing-machine oils. Also, do not over-oil; leakage out a press bearing is usually OK, leakage out a motor bearing gets into the windings and brushes.

If you can post a photo of the motor -and- the name-plate on it, that would help.

Thank you for the quick response, zbang. I wish i could upload the images, but the site is not allowing me. The motor is enclosed, so i’m not sure if I need to open it to get to it or if there’s another way to oil it.

The motor is a Kimble Electric from Chicago. Class LK, Speed 750-2000. Ser.No L71725. Spec No. L-8270. H.P. Con.

Let me know if you need any other information.

look carefully for any kind of hole, plug, or even very small “Ball bearing” looking things. These, if there, should be directly above the bearing, or at twelve O’clock to it, at an angle away from the center. If it needs oil, there Will be a way to put it in. just a drop or 2.

Thanks, Ericm! I do see some small holes. What type of oil do you think I should use for this?

The Kimble Motor company was absorbed into Miehle in 1950s, so it’s old enough have sleeve bearings.

You might consider taking it to a motor shop for cleaning and new brushes. Shouldn’t cost much.

See my previous response for oil :), or ask the shop.

Thanks zbang, i’ll look into a shop!

I concur on 10w or 20w oil should suffice. Any synthetic oil should be fine. You have to remember that today’s oil is far superior to any that was available in 50’s-60’s. look carefully underneath the bearing area of the motor. if there is a hole there on the bottom, this is for excess oil to drain out. A couple of drops ev 100 hrs or so, should be fine.
To address the present noise, a “mechanic’s Stethascope” can be had from any auto parts store, for very little money. Use this to determine that the noise is actually from the motor. very few tools, that for the money, will tell you as much as one of these. If indeed the noise is the motor, a few drops, then a shot of air to push it down and into the bushing may help. Give the oil time to work into the bushing. Noise however, is never good. The oil may prolong the life, but, your motor is going to be due for service. We have a very place here in Milwaukee, Wis. for older motors.
