Rubbers Components

Often overlooked are the parts made out of rubber in your jukebox.

Parts made from rubber usually have a key role in the function of the juke.

It is essential that these parts are in good condition and are not allowed to become hard, brittle, perished or misshapen in any way as this can seriously effect your jukes performance. Age and bad storage contribute to the rubber parts"going off" . In certain positions it is often the constant contamination of lubricants that also contribute to the rubbers failure. SEEBURG

Rumble in the"selectomatic"mechanism can often be pinpointed to the rubber mount discs top and bottom of the motor and/or the motor coupling between the motor shaft and the Mechanism mechanism drive worm.These need to be checked to make sure that they are still resilient or motor noise will be easily transmitted to the pick-up if they have hardened.

Phono motor drive belts are obvious things to check but what about the two rubber mounts holding the motor to the mechanism AND the two grommets cushioning the motor bracket from the mechanism...Usually "rock hard" by now and giving absolutely no isolation,for the pick-up,from the motor vibration. Result quite a racket reproduced through the speakers and very noticeable on quiet records and lead in- and lead out grooves.

ROCKOLA and AMI Phono motor mounts MUST be pliable to maintain their anti-vibration qualities and the correct height for the motor spindle so the idler wheel is positioned correctly.

The idler wheel should not be"rock hard" as it too must absorb motor noise or it will transmit it.The wheel can also be the source of, an often heard rhythmic knocking/bumping noise that emanates from the speakers, in the background of the record that you are playing. This noise is due to an indentation on the edge of the wheel in the rubber:usually caused by long term storage with the turntable in place - the motor spindle digging in to the rubber surface. As the turntable revolves the bump occurs every -time the blemish goes over the motor spindle.

On earlier RockOlas the tone arm pivots at the rear supported by two rubber grommets. This pair of grommets often deteriorate to the point of disintegration causing inconsistent record set-down any where on the record.

The only real cure when rubber parts are affected is to replace them.
