Rockola 1454 running fast

Hi
I have a rockola 1454 and it runs really wall had a few problems in the past but only one issue is outstanding
The problem is the juke plays slightly fast, I purchased a new spring on this site some time ago along with grommets to cure a running noise problem, the spring was too long most probably because the motor or something was non standard, I cut the spring down and noticed less running noise but a higher speed roughly 45 revs in 52 seconds
Is the spring too slack, I don't want to make it too tight and increase the running noise
Any suggestions
The grommets where replaced and the drive wheel appears in good condition

Same problem with my 1448
Had a conversion spring ( 60 >50 hrz )
Result : running too fast ,
Took a piece of emery cloth to sand away a small part of the conversion spring.( making the diameter smaller )
Using a strobe disk sanding away little by little till I had the right speed .

ps , just remove the idler wheel , turntable motor running , emery cloth and you get an even surface.

hi
thank you very much for your very helpful post, it worked and the jukebox is now running at the correct speed, it was a long process but successful

hopefully i will have no more problems

just one thing the idler wheel on my juke can only be replaced as a unit is there anywhere where i can get the replacement rubber tyres from instead of wasting the full wheel,
