Rowe R-74 turntable speed

[Tim S]

I am having a few issues with the play speed as it varies when playing a record.I have a speed coil on the way so that should be installed in a few days.
I have the manual and I am trying to adjust the counter weight. I loosened the lock nut but the counter weight will not turn. I have a stylus force gauge and there is about 9 grams of force on the stylus and I should be at 4 to 5 grams.
Also, is the rubber idler wheel supposed to have play in it? Should I be able to move it up and down on its stem?
Just a few issues I am having. Any info would be greatly appreciated. Thank you all and have a blessed holiday!

Well I fixed the counter weight issue and set to 4.5 grams. Improved play slightly.

Hello Tim,

I normally set up the tracking weight to be about 3.5 grames.

Have you stripped down the turntable motor to remove old lubrication an
the check for wear? There should be up and down movementon the turntabl
motor shaft but no left to right or forwards and backwards movement, i
there is the shaft is worn or the upper bronze bearing.

Check the three rubber mounts, if you are waiting for a speed spring yo
must be in Europe, Australia or New Zealand etc.

The idler wheel linkage should only move up & down if a speed kit wa
fitted to the mechanism for playing at 33.3 rpm as well as 45 rp
records, most home uses disable the linkage solenoid so it plays dinke
or undinked records at 45 rpm.

Thank you for all of the info Alan. I am currently waiting on delivery of a new Idler wheel. I believe the center shaft has too much play in it. I will be removing the motor to clean and re-lube also. I will also look into the rubber grommets. I will set the weight to 3.5 grams and see if there is any improvement. The spring I did not replace, it was the solenoid. It did improve the play to about 90%.
This is my first jukebox and I am realizing I may have a new hobby when I retire in 3 years. It is great that gentlemen like you share your knowledge. Thank you again!
By the way, I am in the United States in Indiana.

Sincerely,
Tim Serbin

Hello Alan,
I received the new idler from needles4jukeboxes.com. The bore hole in the brass bushing was .005 smaller than the rod that it sits on. Took a few thousandths off with some aluminum oxide and she is running perfect!
