Bearing Cap Numbers for MH and 2G Engines A – projection of the bearing cap facing the intake manifold; B – bearing number stamped on the cap

PROCEDURE 1. Install the valves as described above in steps 1–7.

2. Install the hydraulic valve lifters in accordance with the marks made during disassembly, after lubricating them with engine oil. 3. Place the camshaft on the bearings. 4. Install bearing caps No. 2 and 4. Install the cap retaining nuts and gradually tighten them diagonally to torque 6 N·m, then loosen them by a quarter turn. 5. Install bearing caps No. 3, 1 and 5. Tighten the bearing nuts in the same way as in the previous step. Tighten the nuts of cap No. 5 to torque 10 N·m. 6. Install the camshaft sprocket, install the sprocket bolt and tighten to torque 80 N·m. 7. Install the ignition distributor and fuel pump.
