[HELP] Sealed 4.5v Motor Cleaning/Oiling/Opening?

[Rail Co]

Hey Guys! I have an old 1966-1968 sealed (No screws) 4.5v motor. I am wondering if there is a way to actually open it without destroying the casing of the motor? Also is there a way to oil the motor as it is sealed? Is there a good way to clean it? It is very squeaky so I want to oil it so it doesn't kill the motor.

Thanks!

I'm not very familiar with the old motors -- could you post some photos of the motor you have?

I have 2 of them. I will try to get some pics.

Here are some pictures sorry I did not get these sooner!

The top used to have a spongy material but it has since fallen apart. Also the motor uses the old notched wheels that look like this:

Thanks guys!

Hmm. You might be able to drip some low-viscosity oil into the works from below using the axle holes (although I'd have to see the bottom of the motor to be sure). Something like 3-in-1 oil, which usually has a fine-tipped dispenser, might help.

Hi,

a drop of oil placed at the sponge on top is all it needs for a couple of years. After that, attach the wheels and try to turn them gently by hand. If that works connect a power supply by approx. 3Volts (e.g. 2 Batteries) to the motor. The motor should start working - maybe with some noise. The noise should decrease over time. If you recognize the decrease go for full power, i.e. 4,5V

I got 2 of them back to life with that procedure. And they are pretty strong!!

Let me know if it works!

Cheers

I would not recommend 3 in 1. You want a plastic friendly type of oil, such as that sold in model shops for model trains. You may also find suitable oil in shops that specialise in R/C cars etc. Yes per cc it is way more expensive, but as you generally buy it in much smaller amounts and only use a few drops at a time anyway, the initial outlay is not all that much.

Thank you so much! I'll try that whenever I have time to get oil.
