I need torque sequence for rod bearing caps


There is no sequence for the rod caps Since there are only 2 bolts per cap you only have to snug up each bolt then apply half the listed torque value to each cap bolt. then continue back and forth on them until the end torque value is applied to both bolts.

  • Coat the inner side of the bearing shells with engine oil.
  1. NOTE: The crankshaft must rotate freely, if necessary check and adjust the bearing clearances.
    Tighten the main bearing and connecting rod bearing bolts.
    1. Tighten the main bearing bolts in two stages.
      • Stage 1: 25 Nm.
      • Stage 2: 60 degrees.
