AT LP120 Putting new grease for damping the tone arm?

This is just a quick question about what holes to put grease in. I know it's been talked about endless but i still not sure on it. Some people say there 3 holes. I only see 2 and not sure if your putting down the screw hole and the surrounding post, in front of those holes there is one in front a smaller one. I'm not sure if I understand how the lift works to begin with..

I'm going to try this stuff Super Lube® 21010 is an NLGI #2 grease...when I emailed the company this is what they got back and said that Our Super Lube® 21010 is an NLGI #2 grease. Its viscosity is between 800,000 and 1,100,000 cSt
Our NLGI #0 would be a closer fit if you require a thinner grease.

I'm just putting this out there because the video on you tube, there was lots of people who couldn't find the right stuff or was hesitant on what to use. Just my 2 cents..

Hi, first off the damping fluid needed to slow the drop rate of the tonearm is not grease. And super lube which is grease will not work in this area. Super lube is a great grease and I use it in all of the mechanisms I service. But what you need is either 300,000 wt silicone damping fluid or 500,000wt silicone damping fluid like shown in the video. Silicone damping fluid is available on ebay in small tubes or if you have a good hobby shop near by ask them about it. Some hobby shops carry this if they also sell RC cars and trucks. It's used in the shocks to help dampen them so they handle better on rough courses. Who ever made that video did not know what they were doing. The damping fluid is applied to the cue piston that the cue elevator is attached to. It's not gobbed onto the top of the piston or the elevator guild rod as in the video. Now I've never worked on and AT LP120. But I have serviced my far share of Technics 1200 mk2 and other turntables that use silicone damping fluid to slow the drop rate of the tonearm. And since this is a clone model of the 1200 I would believe that AT copied how the tonearm was dampened. The only way to get the damping fluid on the cue piston is to remove the piston from the cylinder. Then clean the piston and the apply a small amount of the damping fluid on the piston. You then push the piston back into the cylinder, spin it a couple of times to evenly spread it over the piston. Then assemble the cue elevator and check the drop rate of the tonearm with the cartridge and counter weight attached. If the tonearm still drops to fast remove the piston and add more damping fluid. If it drops to slow remove the piston clean it off then apply less damping fluid. Unfortunately I cannot tell you how much damping fluid to put on the piston it's a trial and error type of job. The cue piston has to be pulled out from inside the turntable. So the bottom will need to be removed and then you can see what needs to come out to gain access to the cue piston. I hope this helps.

I was just going to buy some of that until I noticed I had this super lube lying around.

Glad I seen these posts, do you have to take the bottom of the turntable to get at this or can you get at it from the top after taking that screw out of the lift?

Thanks

Actually the silicone oil in the viscosities needed for cueing is used in RC cars/trucks in their differentials, not their shocks. The shock oil is much thinner. Sometimes referred to as 'Diff Oil'. But a minor point..

Turntablebasics is well known for long processing times and little to no communication. YMMV, but I'd steer clear.

Ebay has quite a number of listings, a number with shipping to Canada in the $10 range. Search fot 'silicone oil 500000' or '300000'. The 500000 would be more applicable to the mid-mass s-arm on the AT.

I do find it odd there is no hobby shop left in TO and surroundings that has the oil or can order it.

Finally, putting up a 'wanted' in the classified here, on Canuckaudiomart and/or your local kijiji or craigslist would probably net you some enthusiast with some oil to spare ... those 60+ mL bottles of the stuff lasts you for a lifetime!

95% of the time you have take the bottom off. Few turntables allow you to replenish from the top.

On Micro-seiki turntables you just put a silicon oil from the top into a cueing level. If you want to disassemble something like AT-LP120, I am afraid you could just throw it away into a dumpster after that action.

No you do not take the TT apart. You only need to unscrew the lift assembly and remove it (make sure you don't lose the spring). Add a little of the silicone into the trough and replace the assembly. The Turntable Basics silicone is the right stuff for sure and even comes in a syringe to use/store. It's only $10 and I don't remember any kind of crazy shipping charges. Came as ordered promptly.

All the better if you don't need to disassemble on the AT.

As I said, YMMV, but there are multiple threads on multiple forums detailing issues with that vendor.

With Turntable basics, I went o pay the PayPal invoice and he wants 9us to ship, so all together 26.00cad to ship to Canada? I don't think so! Thanks anyway.....

Wow! Throw in in the garbage, little harsh. I know there not well liked on here, but you don't have to be like that.

It was not meant like disrespect to you. But I know how these things are made, especially on a AT-LP120 "hanpin rank". A lot of plastic glued together. If we look at higher "hanpin rank" like AT-LP1240 or PLX-1000, then we can even talk about technical repair.

I was able to buy the silicone damping fluid at a local hobby shop, even in my hick town. OP is from Toronto, where being the center of the known universe, there should be plenty of sources for an item like this.

OP, you need a hobby shop that deals with RC cars and trucks. You're looking for something like "Kyosho #300000 Silicone Oil"
