High starting vibration of the AV80 axial flow fan’s turning mechanism

The AV80-15 axial flow fans produced by Shaanxi Gear Group are equipped with gearboxes made by Mag. During the first start-up of the barring device, the vibration of the high-speed shaft of the gearbox reached 147 um; once the normal operating speed was achieved, the vibration decreased to 90–100 um. At this point, the turntable is stopped and restarted; the vibration of the high-speed shaft of the gearbox is 104 um. Once the rotation speed becomes normal, the vibration decreases to 30–45 um. I would like to ask everyone what the reason is for such a large difference in vibration between the two startups. The turbine, worm gear, and bearings of the turning gear have all been replaced. Is this because the ratchet mechanism is faulty?
