Correct Oil

[simon]

Hello,

I am hoping to disassemble the gripper arm as it is lifting slightly when about to return a record. I have narrowed the issue down to the mechanism having gunk in/around the cylinders.

Here's the problem - I cannot get 3-in-1 20wt motor oil here in the U.K. only the basic 3-in-1 oil. So, does anybody know the equivalent that I can buy to use to lubricate my jukebox? 

(Ron, I won't use my Liberty oil ever again!)

Many thanks.

Simon

Hi Simon,
You probably do not need to dis-assemble it ! (see the griper post above).
Someone said they found a 20 wt ND oil in the UK-- but-- sorry, I can't recall anymore info-- Amazon sells it as well as I think, eBay--
If you find it, please post it in our FAQ's section on oil-- Ron Rich

Hi Simon,
You could use ISO 46 Machine Slideway Oil. This oil is recommended for small lathes and mechanical workshop equipment and has no detergent additives. You would also be OK with (or may prefer?) ISO 68 Machine Slideway Oil which is recommended for larger workshop machines and is slightly thicker. For comparison, sewing machine oil is lighter than both and is ISO 32.

Hi Norman,
Are either of these oils compatable with graphite grease ? What does the "ISO" stand for ? Ron Rich

[jukenorman]

ISO (or ISO VG to be precise) stands for International Standards Organisation Viscosity Grade. I suggested this slideway oil to Simon because it is the viscosity of 20 WT, has no detergent additives and is readily available in smaller quantities. I'm no expert by any stretch, but as far as I can determine it is not recommended to use any lubricating oil in conjunction with graphite grease.

Hi Norman,
Graphite "grease" is powdered graphite, mixed with oil. The graphite grease originally used by RockOla (and Seeburg), can be "rejuvenated" with a SAE 20 wt.ND oil. Ron Rich

Hi Ron,
I totally misunderstood your question! I was looking at data sheets for compatibility but couldn't find any and eventually came across something which said graphite grease shouldn't be used in conjunction with lubricating oil because the oil tends to wash away the graphite film. I take it that what you are suggesting is that old hardened graphite grease can be treated with a tiny bit of oil to "rejuvenate" it? And my misunderstanding of the question shows that I don't know! Although I can't see why not!

Hi Norman,
No problem-- yes, you now understand what I was attempting to say-- when combining a few drops of 20 wt. oil with "old", "caked", graphite grease, the oil tends to re-constitute it, and combine with the graphite to form a lighter viscosity graphite grease. This process does require some "mixing" it up, however--- Ron Rich

Hi Simon
I have sent you a pm about oil, I have some spare.
