MASUMA MGR-2003 timing chain kit for the QR20, QR25, used in NISSAN cars (AVENIR, BASSARA, LIBERTY, MURANO, PRESAGE, PRIMERA, SERENA, TEANA, WINGROAD, X-TRAIL).

Equipment:

  • Timing chain (164 links; 1, 14, 46 are marking)
  • Balance shaft chain (70 links; 1, 18 are marking)
  • Timing chain hydraulic tensioner
  • Timing chain tensioner bar
  • Timing chain damper
  • Timing chain guide
  • Balance shaft chain tensioner
  • Crankshaft gear
  • Camshaft gear

Masuma designed the full set for the timing chain replacement, which provides comprehensive maintenance of the timing mechanism. Masuma timing chains are produced of high-quality alloys, which are special for wearing resistance and durability. The chain rollers are nitrocarburized , so their surface layer is hardened.

  • Ultimate strength (mechanical stress): 13KN (~1325 kg)
  • Outer plate (material – 40Mn, hardness – 47–51HRC)
  • Inner plate (material – 50CrV, hardness – –52HRC)
  • Pin (material – 38CrMoAl, hardness – 88-92HR15N)
  • Roller (material – 20CrNiMo, hardness – 88-92HE15N, nitrocarburizing – 0.15–0.25 mm)

Masuma timing chain tensioner shoes efficiently reduce the timing chain vibration amplitude. They are covered with a heavy-duty polymer, which extends the lifetime.

Timing chain dampers eliminate the residual vibration from the tensioner and prevent the chain from jumping off the camshaft and crankshaft sprockets. They also reduce the noise level. Full replacement of all the assembly parts guarantees the correct operation of the timing mechanism.

As laboratory tests show, slight shifts in the timing angle appear after 19 102 hours of operation under variable loads (bench tests were applied to 1ZZ-FE, SR20). The break-in stand showed a slight shift in the timing angle after 357 000 km. Real world testing shows ~ 241 000 - 287 000 km. According to the tests, the lifetime of the Masuma timing chain kit is at least 200 000 km.

Masuma is a world brand for spare parts, accessories and consumable items for cars. The main brand field is consumables for post-warranty service of the Japanese cars. The company strategy is offering the customers the best reliability and price balance for parts. All the products are produced at dozens of plants, located in East Asia, by the order, technologies and under control of the head company, which is Masuma Auto Spare Parts Co., LTD (Tokyo, Japan).
