Rail Co Posted November 22, 2014 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! -RailCo Share this post Link to post Share on other sites
jtlan Posted November 23, 2014 I'm not very familiar with the old motors -- could you post some photos of the motor you have? Share this post Link to post Share on other sites

Rail Co Posted November 26, 2014 Here are some pictures sorry I did not get these sooner! Top: 4.5v Sealed by Railco1, on Flickr Side: 4.5v Sealed by Railco1, on Flickr 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! -RailCo Share this post Link to post Share on other sites
jtlan Posted November 26, 2014 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. Share this post Link to post Share on other sites
Rumpelmuck Posted November 27, 2014 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!

Heppeng Posted November 27, 2014 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.

I'll try that whenever I have time to get oil. Cheers, -RailCo Share this post Link to post Share on other sites
