Samsung, Astra, Dynatech, and Unitech VCR replacement rubber kits. We have three replacement rubber kits for these Samsung VCRs. MBK-84: Belt Kit Contains all four belts that are used in these Samsung-made VCRs.   The most common symptom of a worn belt is the VCR will attempt to power up then shutdown.  Your price for our MBK-84 kit is $5.00. MBK-84T: Complete Rubber Kit This kit contains all four Belts and the idler tire.  The idler tire will cause the VCR to display lines in the picture that wont track out.  If the tire is badly worn or dried the VCR may try to play and then shutdown shortly after the picture is displayed.  A bad tire can also cause the VCR to eat tape.  Your price for our MBK-84T is $6.00. MBK-84PT: Complete Rubber Kit This kit is a complete rubber replacement kit.  It contains all four belts, the idler tire, and the Pinch Roller.  If the pinch roller has never been changed you probably need one.  If the pinch roller has a hard glaze on it or the capstan shaft has a black buildup the pinch roller has probably been slipping.  This kit is a complete rubber replacement kit for these VCRs.  Your price for our MBK-84PT kit is $12.50.
