2017-12-6  If you can, measure the drive belt. My belt was down to about 27mm when it got replaced. The belt should be about 32mm. Look for black dust on the pulley and belt guards, easier on the LT than the Storm. When the bearing is really bad, the drive belt will be loose and pushing on the belt will cause the pulley to wiggle.

SOLID MECHANICS DYNAMICS TUTORIAL – PULLEY

2005-11-28  The force (tension) in a pulley belt increases with torque and power. The maximum power that a pulley system can transmit is ultimately limited by the strength of the belt material. If this is a problem then more than one belt should be used to share the load. If the belt does not break then the possibility of the belt slipping exists and this

1. Random cracking across the ribs. Appearance: Small yet visible cracks along the length of a rib or ribs.. Cause: Continuous exposure to high temperatures and the stress of bending around the pulleys leads to cracking.Cracks begin at the rib top and grow to the cord line. As a rule, if cracks appear 1 or 2 cm apart, 80% of the life is gone and the belt should be replaced.

2009-1-23  The belt–pulley contact was formulated as a linear complementarity problem together with a penalty method. This made it possible for us to accurately predict the contact forces, including the stick and slip zones between the belt and the pulley. The belt-drive model was verified by comparing it with the available analytical solutions.
