If the motor hasn't been lubed for awhile, might not be a bad idea for a drop (NO MORE!) for each exposed shaft bearing after a quick swish with a mineral spirit wetted Q-tip swap at the base of the exposed motor shaft(s) to clear whatever crud may be lurking. I drained the factory fill lube out of the bearing, flushed with mineral spirits ('paint thinner') several times and refilled just above the ball thrust bearing with 75W-90 GL-5 hypoid gear oil. I like a viscous lube such as gear oil - it it's good enough for Rega, it's good enough for me (at least it smells like hypoid gear oil on my Planar 3.). If the platter is spinning at the correct speed, it will be within +/-2 of the specified speed. Most turntables have a built-in speedometer that allows you to check the platter’s speed. There are a few ways to check if your player is playing too fast: First, check the speed of the platter. As others have suggested, clean and lube the TT main bearing. How to check if your player is playing too fast.
