Will a record weight harm the motor in a direct drive turntable?

On my Yamaha PX-2 direct drive, I am using a VEM Record Clamp which is not very heavy but has Dynamic Damping.  Seems to work great.  

@bobsdevices Yamaha PX-2 DD, I so wish I chose this model over the TTS 8000 when I was collecting Vintage DD TT's to have fun with.

The GT's had crept in Value and were quite a few £'s more than other selections made. Mind you they would have been a great investment, as typically they are the best part of 200% appreciated in today's money, where as my TT's are still found at similar monies as when acquired by myself.   

How much weight exactly are you wanting to add?

I have a Kenwood KP-9010 and Kenwood sold quite a few accessories one could purchase to enhance the performance of these DD tables.

All the accessories that were sold for the L07 Kenwood's would work on the KP-9010, KP-1100 and maybe others.

Pretty sure the DD motor on your 59L is a high torque model. I'm not gonna say "no problems" as I have no idea how much weight you're talking about....

Has your table been restored? Caps, resistors, brought back to spec?

If not, and you're running all original electronic parts inside the TT I'd probably not try at all. If you're thinking of adding weight I'd have the TT internals restored/upgraded first.

Aldo, I own an L07D and the record weight that optionally came with it. I’d guess it weighs 250g, tops. I also use it on a Victor TT101 and on my Lenco which has a massive aftermarket bearing. But the problem is when you get up over 500g or even more, which some do use.
