Rega planar 3 bearing and oil


I recently reoiled my rega planar 3 bearing. It had oil in it, and on the shaft of the subplatter, and the turntable had no obvious problems, but I figured it was probably due for it's 3000 mile change, and besides, I like to tinker !
I removed the ball, inspected and thoroughly cleaned all surfaces using isopropyl alcohol, and then added a few drops of castrol hypoid gear oil (as recommended by rega) and checked that the new oil was drawn to the very top of the subplatter shaft.

To my amazement this has resulted in a considerable improvement in the sound of the turntable. Gone is any hint of glassiness or sibilance in the high frequencies, that used to make the deck sound very very similar to my CD player. The sound is just as detailed but beautifully smooth. I wasn't expecting anything like this ... but for $4 of oil (and I have quite a bit left over :-)) I'm very happy.

So any brave owners with old rega decks try changing the oil ... you might be very pleasantly surprised.

On a related issue I noticed that some high-end decks come with ceramic or saphire bearings, of very high tolerance. I have found that www.bocabearings.com can supply such bearings for around $4. Can anyone think of a negative impact of trying a high-precision bearing in the Rega ? Should I stick with steel ? There is an aftermarket subplatter for sale at music direct that uses a ruby bearing.

A bearing company that sells small bearings.They can be oredered online,make sure you get the correct size and you only need one.
At the risk of being pedantic here is Rega's official recommendation for lubrication.> Cleaning Hub/Bearing
> 1. Undo hub nut and remove washer. Remove hub/bearing from turntable. As the brass bearing bush is designed to fit tightly in the plinth, gentle tapping on the base of the bearing bush with a plastic hammer may be necessary. (We advise that this is not done in front of the customer!)
> 2. Slowly withdraw the hub from the brass bearing bush, (if the hub is pulled out quickly the ball bearing may inadvertently be sucked out and lost). Remove ball bearing by turning the bearing bush upside down and tapping sharply.
> 3. It is important that both the hub spindle and the inside of the bearing bush are cleaned and degreased thoroughly. This is best done using a solvent cleaner containing 1.1.1. trichloroethane which is available from R.S Components Ltd. A small amount of this can be poured into the bearing bush, and with a finger placed over the hole, shaken thoroughly and poured out. To clean the spindle apply the solvent to a piece of lint-free cloth or kitchen paper. Wipe both spindle and the ball bearing with same and replace.
> 4. Fit the hub back into the bearing bush and spin to check that it is running freely. If its not, return complete assembly to Rega
> 5. If all is well, remove hub from bearing bush then tilt the bearing bush and place two drops of Comma Hypoid EP80, Castrol EPX80w/90 or Shell Spirax EP90, as recommended, in the position as illustrated. Do not use more than two drops.
> 6. With the bush still tilted, slide hub (without twisting) back into bearing bush. This method should ensure a release passage for trapped air.
> 7. Spin hub to evenly distribute oil and refit into turntable. Replace washer and tighten nut firmly, using an adjustable spanner or Rega tool, to approximately 5Nm, (a full explanation of this torque can be found on Explanation of torque)
> IMPORTANT
> It is essential that the recommended oil is used as any other lubricant will break down under pressure, causing wear. It is available from most car accessory shops or from Rega, free of charge.
> Degreasing: RS Components stock a solvent cleaner containing 1.1.1. trichloroethane which is suitable for degreasing the hub/bearing assembly and lift lower assembly. Please note warning on solvent tin
Tes we should have told you.It is 3/16th of an inch size or the metric eqivalent.Look for a silicone nitride or "ceramic" type.Other boutique companies sell a manufactured "Ruby" bearing as well.The ceramic ball should be fine and is ten times stronger than the normal steel one.This link sells a metal sub-platter for the P2 with a "ruby" ball.http://www.groovetracer.com/subplatter_groovetracer.htm
