Plastic tensioners for the Cayenne.The timing change tensioner for the Porsche Cayenne The Porsche Cayenne is a mid-size luxury SUV produced by the German automaker Porsche since 2002, and North American sales began in 2003. It is the first V8 engined vehicle built by Porsche since 1995, when the Porsche 928 was discontinued. is actually a plastic assembly, not metal as is often the case. Specifically, the component, produced by German suppler IWIS i·wis also y·wis adv. Archaic Certainly; assuredly. [Middle English, from Old English gewis, certain; see weid- in Indo-European roots.] (www.iwis.com/en), is a two-piece assembly. There is a wear-resistant grade of Stanyl (TW341) for the top layer that presses on the timing chain and a high-stiffness grade of the polyamide polyamide material used in the creation of nonabsorbable, synthetic, nylon sutures. (TW241F10) used for the tensioner base. "According to Ton Vet, application development manager for Stanyl at DSM 1. DSM - Data Structure Manager. An object-oriented language by J.E. Rumbaugh and M.E. Loomis of GE, similar to C++. It is used in implementation of CAD/CAE software. DSM is written in DSM and C and produces C as output. Engineering Plastics (Evansville, IN; www.dsm.com), "In the IWIS design, the tensioner base can be made as stiff as needed as needed prn. See prn order. by using high-stiffness materials. At the same time, the top layer can offer a non-abrasive surface to the chain for maximum life with minimum wear and friction." The top layer comes out of the mold with a smooth finish, including with the gears to guide the chain; the bottom layer is molded in its final shape, including all reinforcing ribs and mounting and pivot points for assembly.
