Maybe a adjustable trim pot can be wired in series to the spindle, in order to control the speed of the motor? Or a small potentiometer of some sort that would make a great mod for this turntable. Therefore the belt shouldn't be an issue. You can always adjust your motor to the proper speed. Just a thought
Interesting…I actually resolved the issue by completely taking the motor apart (for the umpteenth time) and doing a deep clean with acetone on the bearings. Once I did that it consistently gets up to speed within 10-15 seconds.
For anyone with the same speed issue on my PL 50, don't shave down your spindle. Get the correct belt. The wrong thickness will cause the table to run fast.
I agree, but how many belts have you found you need to go through to get the proper length/thickness? On this particular table I went through a few and reading more forum posts than I care to admit, found that speed issues on these are very common given the lack of properly sized belts and the design of the table.
I cannot get the steel plate to come off, you made it look so easy. What am I missing??????? Ty
The platter? Tap the spindle with a screwdriver handle and few times.

The correct thickness should be
.025" 35.1" length of belt..
I found the dimensions for the Thrust Bearing online.
Bearing measures .420" in diameter x .081" high. Delrin should be used.
Thought I'd share..😊
Thanks for the tip!
hello i have the same tt, same issue can you tell me what was inside the spindle.
Inside the spindle housing (on the bottom) is a thrust bearing assembly.
Same speed on mine after starting with a much slower speed as well. I'm not as handy as you so thanks for making this video
I'd start off by checking out the thrust bearing.
