In this video I cover some basic service tips per a viewer request, as it pertains to servicing some of the older turntable motors. #turntable #recordplayer #vintageaudio
I cannot figure out how to get the motor “open” on my Magnavox Drum Table turntable. I removed all the screws, got it disconnected from the main body, but can’t get the thing open.
Pardon the delay in getting back to you, I've been extremely busy. Are you still having problems getting the turntable motor opened up? Hopefully by now you were able to get it figured out, but if not let me know and I'll see what I can do to help, it would be better for you to email me at ernest@retroelectrotech.com
If you are going to take it apart then you should drill the rivets and clean the old oil out of the bearing and felt wick. And flip the sacrificial disc over or sand the divot out from the shaft spinning on it. If you don’t do it proper you shouldn’t do it at all. Mixing new oil on to old oil will create all sorts of problems.
I agree if a person wants or needs to go deeper especially when servicing a unit that's in rougher shape, by all means, do so. However, when performing more routine servicing on motors / bearings that are not particularly bad, I've seldom run across issues "mixing the older with the newer" on the felt wick, it's done all the time. Again, I agree that is a more thorough method when needed but not practical in all service applications, thank you for chiming in.
Hello, I was wondering if you have any information about the motor in a CJ WALKER 55 turntable. The motor is making a knocking noise, almost like it's bottoming out. The turntable is from the mid 80's but it sat idle for 35 years. Any suggestions would be greatly appreciated. I forgot to mention that I have access to a lathe, so if there's a compatible motor, I can cut a new pulley. Thanks again for any information.
Hello there, I've heard of folks performing some mods to resolve that issue, just search for "CJ Walker 55 motor mod" or something like that, and I'm sure some information will "pop up". I haven't performed that particular modification and typically don't perform mods (unless it's a safety issue) on customer equipment. It sounds like you have the knowledge and ability to produce the needed parts (there may even be a kit available?) to resolve the issue once you research the fix. I glanced at some info very briefly (because I'm super busy), and it looked like a straight-forward modification. Thanks for chiming in, I wish you the best 🙂
Pardon the delay, I've been extremely busy, a good start is to assure that there isn't any friction causing mechanical resistance. If there is surface rust, oxidation, dirt, degraded lubricant and or everything is just all dried out around the bearings / shafts etc., then you'll want to get everything nice and clean and re-lubricated. Beyond that, if there is a problem with the motor electromagnetically, you may want to just find a replacement. First try assuring everything is clean, smooth and lubricated appropriately, and of course check all associated connections.
