Check and replacement

PERFORMANCE ORDER
1. For check of a condition of the plug shake the driveshaft in the cross-section direction, having unscrewed bolts and nuts of fastening of the elastic coupling to a flange of a shaft of a check point. If it is felt appreciable люфт, the plug replace.
Prevention
