In the next few weeks I hope to start rebuilding my Empire 689. It has been sitting for a few years I’ve had it....no idea how long it sat idle before I got it.
The part I am most uncomfortable with is the motor. Is there any specific procedure in approaching this? Just lube the bearings...?
I plan to disassemble it as much as possible, do a total cleaning, polishing, lubricate...I am thinking any caps or resistors should be replaced too. :?
Any pointers and suggestions will be gratefully received.

those motors are really good, I was just wondering what yours is doing that requires attention

I have a 598 that I have done some work on and want to do more, I have a sme 3009 that I am going to install and I was thinking of replacing the top deck with slate as I think that does some things to the table vibration wise. Awesome heavy platter my motor is dead quiet

The first thing I did with mine was to get rid of the delrin thrust pad and replace it with tungsten carbide a la Oracle. Rumble disappears.

I actually salvaged mine from an electronics recycling container some time ago. Been sitting on my work bench while waiting for some other projects to get out of the way...and finding some time. The time is nigh.
All I know is that when I plug it in...the lights come on. Definitely needs a belt.
I did not want to do any inadvertent damage by being too eager to see what makes it tick...wanted to play it safe and smart...neither are my strong points. :roll:

Another question...what’s the difference between a 689 and a 689 Troubadour?

Nothing..... and it's 698. There's a fellow stateside that builds replacement IC's with the odd 5 pin connector for the arm. I've two if you need one but in my opinion they're somewhat lacking in "panache".

Looks like you may have your work cut out for you judging by the arm. Those 698 headshells are hard to come by. Those tables are pretty darn quiet so I can't see a real need for a thrust bearing swap unless there's an issue. Also watch out for the belt length; there were a number of changes over the production runs. The most common seems to be a #508 belt (Turntable Basics FM 31.5).

I really love my 598 and BTW..... the arm isn't nearly as massy as they appear.

Ok now it’s like you are speaking a different language. Oh my I better do some research. Thanx though, sounds interesting.

Oh my yes...698. :oops:
I do have a good headshell that I sourced from a fellow CAMer last year.
Thanks for the tip on the belt size...I noticed a few suppliers had two different sizes.
Another fellow CAMer today has been a huge blessing.
Can hardly wait to have this table working.
Already wondering what will be the first LP to play.

The best belt that I’ve used with my 698 is the True Speed Belt for Empire 698/598/498 from Esoteric Sound.

https://www.esotericsound.com/access.htm

All others that I have tried were too thick causing the speed to be slightly fast.

I own a vintage Empire 698 as well. Looking forward to following your rebuild experience. Have read a lot about belt size problems with these decks. The original belt on mine (a one owner) was very thin compared to other BD tables I've had. It finally stretched beyond usability, so the machine has sat on a shelf for a few years. When in service, it was a very good sounding vintage deck. Well worth restoring.

FYI ... Here are speed measurements that I made using the Esoteric Audio True Speed Belt.
