I got a ingersoll rand sp-54 roller
Just put new berings in the Vibratory
And can not find any information on how tight to make the drive belt
Thanks all

The power belts should be much more stable than individual V-bands. That said, do a little Google and visit websites like Dayco, Gates and Good Year. They have information regarding belt deflection. Whether it's a 16" or 60" span, they should spec the deflection for your chosen brand.
When dealing with older equipment, as you are, the books are either long gone, on a micro-fiche forgotten somewhere or in someone's private stash that they forgot they have. In times like this, default to the suppliers information.

The only problem with the belt is the tension is constantly changing
The drive motor is mounted to the frame the shaft is is mounted to the brum
The drum is mounted to the frame with rubber isalator blocks
So as the drum is going up and down the belt gets loes and tight

Was a poor design on IR’s part for sure !!
IIRC, the rubber drum isolators need to be in decent shape to limit the amount of drum travel in relation to the vibratory drive motor.
In my one and only SP54 vibratory belt experience , I believe I tightened the banded joined belt gradually until it no longer slipped.
At vibratory start up there was always a split second “chirp” sound from the belt that I could never eliminate.
