Timing chain replacement kit MASUMA MGR-9004 for N43B16, N43B20
engines, which were installed on BMW cars (1-SERIES (E81, E82,
E87), 3-SERIES (E90, E91, E92), 5-SERIES (E60, E61) Timing chain

chain tensioner Timing chain damper Crankshaft gear Masuma produces
a complete kit for replacing the timing chain, which allows you to
comprehensively service the timing 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-9004 for N43B16, N43B20
