PULLEY DIMENSIONAL REFERENCE IDENTIFICATION INSTRUCTIONS DAYCO IDLER/TENSIONER PULLEYS The advanced technologies employed in the materials research, engineering and manufacture of DAYCO idler/ tensioner pulleys has earned them a reputation for quality long lasting performance. Maximum structural integrity and optimal design are guaranteed through “modeling” using state-of-the-art 3D Computer Aided Design software and Finite Element Analysis. The manufacture of either our specially formulated glass filled polymer (plastic) pulleys or metal pulleys with smoother surfaces and tighter dimensional tolerances reduces vibration which translates into a cooler running belt and ultimately longer belt life. Lifetime lubricated ball bearing and high temperature grease and seals assure peak bearing performance. These elements working together all provide the smooth, quiet drive service that both the Automotive OE and Aftermarket demand.
