Admiral 5RP4 Record Player issues

Bill, why would I change the spring's location from it's stock factory position?

Because it looks like it isn't in it. Have you got the repair mannual on it?

Are you sure you re-installed motor properly after replacing grommets? Did you replace motor grommets? If not, motor may be sagging??

I replaced the grommets with silicone rubber that I applied myself. I guess it's possible I didn't judge the correct distance when performing this job. Where would I locate such grommets?

There's your problem. You did the job wrong.
You need to go to Gary Stork at VM enthusiasts, and, buy the correct grommets.

Thanks Bill, I hope they do the trick!

I hope they do the trick. Gary said this is the first call for the Admiral grommets, and, he's excited.....
I'm buying an Admiral 45 rpm adaptor to finnish my table model bakelite radio, phono.

Looking at your mechanism, you may have a bit of dirt or grit so it might also be under the moving plate(s) or a metal burr, or bent piece that would prevent total movement. Just an observation. Clean and re-oil!

New motor grommets did the trick! Thanks to everyone who helped!

cool glad it worked
