TIMING CHAIN KIT  MGR-4001

Timing chain replacement kit MASUMA MGR-1001 for 1KR-FE engine , which was installed on TOYOTA (AYGO, PASSO, VITZ, YARIS, YARIS) cars.

Equipment:

• Timing chain (Number of links - 124; marking - 1, 7, 33)
• Timing chain tensioner
• Timing chain tensioner bar
• Timing chain guide
• crankshaft gear
• Camshaft gear

Masuma produces a complete  timing chain replacement kit , which allows you to comprehensively service the timing mechanism. Masuma timing chains are made from high quality alloys that are wear resistant and durable. The rollers of the chain 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 a heavy-duty polymer material for a long service life.

Masuma timing chain dampers dampen residual vibration after the tensioner by preventing the chain from slipping off the sprockets on the camshafts and crankshafts. Reduce noise level. A comprehensive replacement of all parts of the assembly ensures the correct operation of the timing.

Laboratory tests showed that slight shifts in the valve timing began after 19,102 hours of operation at variable loads (bench tests were carried out on engines - 1ZZ-FE, SR20). The ""running stand"" showed - a slight shift in the phase angle, gas distribution began after 357,000 km. Real world testing ~ 241,000 - 287,000 km. Summing up the results of the tests, the life of the Masuma timing chain kit is at least 200,000 km.

Guarantee for the timing chain kit is 24 months or 80 thousand km. mileage only if timing chain kits are installed at Vehicle Service Stations or Authorized Service Centers. Do-it-yourself timing chain kits come with a 14-day limited warranty from date of purchase.
