78639600 Kolbenschmidt TW SET

A Timing Belt Kit, the TW SET is designed for use within the crankshaft compartment of an engine. Its primary function is to ensure accurate timing in engines that require precise control over crankshaft rotation. This kit offers several technical advantages, including enhanced timing precision and prolonged lifespan of engine components. Crankshaft bearings are precision components facilitating smooth rotary motion between the crankshaft and engine block. Located within the engine’s main and connecting rod bearing bores, these bearings support significant loads and reduce friction generated by reciprocating piston motion. Typically manufactured from tri-metal or polymer-coated steel, they feature a split design for ease of installation and precise clearance control. Oil grooves and channels within the bearing surface maintain a hydrodynamic oil wedge, preventing metal-to-metal contact. Dimensional accuracy and material hardness are critical for maintaining engine performance and longevity, with variations existing for different engine families and load requirements.
