I think the problem with the table spinning too fast may be caused by modern replacement belts being thicker than the original equipment. I’ve had this problem with several turntables, including a Revolver Rebel that takes a round cross section belt. The new belts were a few hundreds of an inch thicker than the originals. I ran across an article some time ago explaining the physics/ engineering of why the thickness of the belt makes a difference, even though you think it wouldn’t. Can’t remember the details right now.
@@millervintagehifi3034 I see there are EBay sellers now offering a "thinner" belt for the Pioneer Pl-50, which is what I'm working on. I also need to replace the thrust bearing. Your video is very helpful.
The seller Pats Audio on eBay is where I got them from. Belts can be tricky…I’ve had to try a few belts from different vendors to get the correct size.
If you will take the sharp tip of a knife blade and gently slip it between the inner rim of the platter and the inner rubber mat, the inner rubber mat lifts out, revealing four large holes which can be used to lift the turntable off of the shaft.
@@millervintagehifi3034 yea that is the way I will do it like you did. I have seen where people say to add 2-3 teaspoons of oil that seemed like a lot to me Thank you for your help.
I have this turntable but it (sometimes) makes a grinding sound when it spins. I am guessing because it was not oiled regularly. Any idea what needs to be done to fix it?
I would suspect the thrust bearing first (the platter won’t sit high enough to clear the top of the table). If you spin it by hand does it make the sound? If so I’d look at the thrust bearing first.
@@millervintagehifi3034 thanks for the reply. I actually added some oil to the spindle shaft and it seems to have done the trick. I did this without taking the bottom off and actually removing the shaft. But so far - grinding has stopped. If it starts again I’ll try spinning it by hand to see if it still happens and (if it does) - I’ll make the replacement you suggest. I had it fixed once since I bought it 10 years ago (same problem) and it worked fine for a couple of years before the grinding came back. The person who fixed it had it for 16 months before fixing it so I’m determined to do it myself this time.

Totally agree...I think overall belt dimensions (length, width, thickness) all contribute to speed issues.

Great video! Where did you buy the replacement thrust bearing? Also, any recommendation on replacement belts?

Thanks for your time on this turntable repair; really great app you use for calibration data. Is it available to non professional types?
Free download from the Apple app store. I used another one before, but don't recall the name. I prefer this one because of the database.

Thanks for the tip!
Great video I am about to do the same to mine. Do you add oil to the cap with the thrust bearing.
I add a few drops...probably not necessary since oil will eventually make it's way down there anyhow.

Thank you for your help.
Definitely not tsp...that's insane.

Factory and Flutter spec for that TT is .08.
I don’t know that I trust the W&F readings on the app that I use. I think the speed is probably OK.
It is easy to remove the middle rubber mat
On the top of the platter? I found out that it just pops right out.
