Park Tool PCS-10 stand sticking

I’ve had a Park Tool PCS-10 stand, it’s about 7-8 years old.

There’s a compression sleeve and cone set that allow the clamp to rotate the bike up and down. They’re made of black plastic (ABS?) and I can’t find any guidance on lubrication.

The problem is that once it’s tightened to secure the bike from rotating, I need a hammer to break that “stiction” between the nut and sleeve. Once it breaks free it spins fine.

I’ve tried grease, assembly compound, and anti seize. It’s been either too loose or still sticking.

Trying some MSW now, which seems promising.

Anyone else have a method?


I have the same and it’s been sticking for years. Following to see if anyone has fixed it.

My 9 is the same. Following… Need a breaker bar to move it.

Have you actually disassembled the head and cleaned/lubed everything or are you just spraying lube in the gap between parts? I’ve pulled mine apart a few times, cleaned it up, sprayed it with dry lube, and reassembled and it still works great.

Yes, several times I’ve had it apart, cleaned, put back together and it would still stick.

At one point I had greased it, but then it was hard to get it to hold a bike from rotating.

I tried some Molten Speed Wax, and that seems to be working for now. Didn’t melt it, just put some grains in there and tightened it up, cleaned out some of the excess, and it all seems to work pretty good now.
