Dear All,
The arm-lift of my Hadcock 228 Export drops so fast because there is no more sticky grease on arm-lift cylinder. Can anyone tell me what is the name of such sticky grease? Which type of store sells that grease.
Thank you very much

I had the same thing happen on a rega rb300 - the sob would drop like a rock. I tried a couple of thick greases I had laying around (bearing greases) and, if anything, it dropped faster. I e-mailed Rega off their web page, and they told me that the RB-300 cuing mechanism uses Rocol Kilopoise.Rocol Kilopoise is a damping grease designed to add friction. Try a google search for damping grease. It is used in cameras and microscopes so a camera shop might be able to supply a small amount. I don't think it is interchangeable with silicone, so it is best to ask the manufacturer how to proceed.
In my case, a new cuing mechanism for the rega was $45 so I went with that rather than do trial and error on different greases that might or might not work.
If the mfg. says to use damping grease, the link below has two types available. I thing the heavy nyogel looks like the best bet. Disclaimer - I have never ordered from micro-tools.

But since that's available in different viscosities you'll need to know exactly what a Hadcock 228 uses. Try a search if no one comes up with the precise answer.BTW, you MAY be mis-understanding how the mechanism works. Most damped arm lifts have the oil inside the cylinder. That oil you saw on the outside may have been leakage. Once enough oil leaks out the mechanism will no longer damp, as you're now experiencing. If that's the case you'll have to open and refill the cylinder.

Contrary to popular belief, the silicone is not usually a thin oil in a sealed piston/cylinder like a shock absorber but very thick goo in an unsealed cylinder with a rather loose fitting piston. When new it is so thick it won't really run but after a very long time it can ooze out and there goes the damping. There really isn't much there, just a coating on the cueing rod/cylinder.
about the arm you have. Failing any more informed responses you might want to give it a try.
