Rega Planar 25 problem


My Rega Planar 25 has an obvious problem: the small round black plastic piece that fits over the motor spindle (i.e. the little shiny steel rod. about 1/8" diameter, that turns with the motor)is not fastened to the motor spindle: it can be lifted off with no effort, so it isn't a friction fit, and it shows no sign of glue or cement or the like.

Does anyone know how these two pieces are supposed to be held together? I have a Rega Planar 3 too, and what look like identical parts (except with no shiny steelin sight) are firmly held together. It's a mystery why my 25 ever worked, but however that may be, it sure doesn't now!

Can anyone help? I posted a similar message some months ago and was told to contact the USA Rega distributor, which I tried to do. No answer came back.

Thanks,

STEFANI, the table was purchased brand new as older stock last week. I cracked the seals on the box myself. The table was manufactured in 2004.

I see no belt slipiage either. The platter on start-up need just the tinyest of nudges to get going. What I think is going on, is because my motor runs a little slower than most(correct speed), it has a little harder time on start-up. Maybe this is why most tables run a little fast to begin with, to rid of the start-up hesitation. (Lower torque).

What do you think, is my hypothesis correct or reasonable to say it is just a characteristic?
I have heard of Rega tables (P25 P2&P3) running correctly on speed.

It needs just a little
Jeffjarvis, you had this same pronlem before?

If so, did you see a leak of oil anywhere around the subplatter before doing so?

Thanks,
According to Rega, fast speed is attributed to an old drivebelt and loss of oil. This is what was said to me in an email from them. It goes against everything we all thoughtbut who knows, they must know what they are talking about.
Last weeks I ALMOSTY went through this. I was having a problem with my 25 where the motor could not start the glass platter on start-up without a nudge. The platter would just sit there unless I nudge it. I emailed Rega (very helpful) and they told me to check to see if the pulley is loose from the shaft like you describe. I did check it was not loose but they told me if it was to put a couple of drops of superglue as STEFANI describes above. This is how it is held together in the first place. The glue may come loose over time but hardly no one notices or checks.

Be sure to line up the pulley correctly (not too high or not too low) so that the belt wont slip off the subplatter when in rotation on either 45 or 33 settings. This was also described to me by Rega.

If in doubt email Rega directly, they dont bite. Very helpful buch of people.

BTW - for my situation the pulley was not loose at all, the platter spins exactly at 33 1/3 with stylus drag. So I just chaulk it up to a characteristic of my table. Unless anyone diagrees or has any opinons here, that would be great.
STEFANI, I tried my friends P25 belt after reading your suggestion to try a new belt. I tested his tables speed and it does runa bout 1% fast. With his belt on my table, my table does the same thing.

The manual does state "allow for slow star times and giving the platter a nudge would help speed things up" Granted it does NOT say the platter won't start otherwise.

My motor does not seem to be running slow. Using a KAB speed strobe with stylus drag as a factor it runs at what Rega says it should run at which is 33 1/3 + or - .05%.
Mine is runnig at .03% fast (with either belts) which is basically dead on. I have heard of some Rega's running fast but also I do believe most run on speed. However, the start-up thing.

This start-up issue was concerning me until I realized the speed of the table is steady and right on speed. Also your help as well with troubleshooting also made me feel a little better. Unless you think there is still a problem, if you do I'm open to ideas.
