To fit
1 Clean the bearing faces of the connecting rod and the crank pin.
Cautions:
- Engine models RG, RH, RJ and RK have a different shell bearing fitted to the cap and connecting rod.
Ensure that the relevant shell bearing is kept with the correct cap or connecting rod.
- Do not stamp or punch the connecting rod assembly, as this could cause a fracture.
2 Clean the complete bearing and lubricate the bearing surface and the crank pin with clean engine lubricating oil.
3 Fit the upper half of the shell bearing to the connecting rod; ensure that the bearing shell is fitted centrally (A1). Fit the connecting rod to the crank pin. Ensure that the forged marks (B1) face to the front of the engine.
Note: The fasteners used with these connecting rods must only be used once.
4 Clean, lubricate and fit the lower half of the shell bearing into the cap; ensure that the bearing shell is fitted centrally (A1). Fit the connecting rod fasteners. Fit the cap to the connecting rod. Ensure that the assembly has both of the forged marks on the same side (B1).
5 Tighten the new fasteners to an initial torque of 18 Nm (13 Ibf ft) 1,9 kgf m.
6 Tighten the new fasteners to 70 Nm (52 Ibf It) 7,1 kgf m. The fasteners must then be tightened a further 1200.
7 Ensure that the crankshaft rotates freely.
8 Fit the lubricating oil pump, see Operation 10-10, or fit the balancer unit, see Operation 5-15.
9 Fit the lubricating oil sump, see Operation 10-5 and fill the sump to the correct level with lubricating oil of an approved grade.
