Crankshaft - Installation

caution
Always check the bearing journal clearance (see Connecting Rod Big End Journal Checking, Measuring and Bearing Selection and Crankshaft Main Bearing/Journal Checking, Measuring and Bearing Selection), before final assembly of the crankshaft. Failure to correctly select crankshaft bearings will result in severe engine damage.
    caution
    Ensure the three piston cooling jets are installed. If the piston cooling jets are omitted, oil pressure will be reduced. Running the engine with low oil pressure will cause severe engine damage.
  1. Select and fit new main and big end bearing shells using the selection processes (see Crankshaft Main Bearing/Journal Checking, Measuring and Bearing Selection).

  4. Ensure that the crankshaft is clean, and that the oil ways within the crankshaft are clean and free from blockages and debris.
  5. Refit the balancer (see Balancer - Installation).
  6. Install the crankshaft ensuring that the crankshaft journals align with the big ends and that the crankshaft and balancer gear markings align as shown in the next illustration.
