| Timing chain replacement kit MASUMA MGR-9023 for the M57D engine, which was installed on BMW cars (3-SERIES (E90), 3-SERIES (E91), 3-SERIES (E92), 5-SERIES (E60), 5-SERIES (E61), 6-SERIES (E63), 7-SERIES (E65), 7-SERIES (E66), X3 (E83), X5 (E70), X6 (E71)). Complete set: Timing chain (Number of links - 74) Fuel pump chain (Number of links - 66) Oil pump chain (Number of links - 42) The gear wheel of the pump of the injection pump Camshaft gear Masuma manufactures a complete kit for replacing the timing chain, which allows for a comprehensive service of the gas distribution mechanism. Masuma timing chains are made from high quality alloys, which are distinguished by wear resistance and durability. The chain rollers undergo a nitrocarburizing process, due to which they have a hardened surface layer. Tensile strength (mechanical stress): 13KN (~ 1325 kg) Outer plate (material - 40Mn, hardness - 47-51HRC) Inner plate (material - 50CrV, hardness - 48-52HRC) Pin (material - 38CrMoAl, hardness - 88- 92HR15N) Roller (material - 20CrNiMo, hardness - 88-92HE15N, nitrocarburizing - 0.15-0.25 mm) Masuma timing chain tensioner shoes effectively reduce the vibration amplitude of the timing chain. Coated with heavy-duty polymer material for long service life. Masuma timing chain dampers dampen residual vibration after the tensioner, preventing the chain from sliding off the camshaft and crankshaft sprockets. Reduces noise levels. Comprehensive replacement of all parts of the unit guarantees the correct operation of the timing. Laboratory tests showed that minor displacements of the valve timing began after 19,102 hours of operation at variable loads (bench tests were carried out on engines? - 1ZZ-FE, SR20). The break-in stand showed - a slight displacement of the phase angle | Timing chain replacement kit MASUMA MGR-9023 for the M57D engine, which was installed on BMW cars (3-SERIES (E90), 3-SERIES (E91), 3-SERIES (E92), 5-SERIES (E60), 5-SERIES (E61), 6-SERIES (E63), 7-SERIES (E65), 7-SERIES (E66), X3 (E83), X5 (E70), X6 (E71)).
