ASSEMBLY Always use new gaskets, sealing rings, sealing washers and lock-washers . Coat the sealings with grease or oil them and also oil all moving parts prior to installing them . If the engine is fresh-water cooled, see page 21 . 1 . Heat the crankshaft gearwheel to approx . 150°C (302 ° F) 3 . Turn the piston rings so that the gaps are offset in relation to each other . The piston crown is marked with an arrow that points towards the belt pulley . Use installation ring 884813-7 . prior to the installation . Place the key in the key-way of the crankshaft and press on the gear wheel . Oil the new main bearing halves (with oil hole) and install them in the block . Put in the crankshaft .
NOTE! The main bearing shell at the Fit the caps with the marking aligned with the crankshaft's marking . The crankshaft can be turned in any direction towards the piston . Tightening torques : Step 1 : 25 Nm (2.5 kpm) (18 ft/lb) Step 2 : 70 Nm (7 .0 kpm) (53 ft/lb) flywheel also functions as a thrust-bearing . 2 . Oil the cap bearing halves and install them . Install the caps in accordance with the marking in the block (2001 has no intermediate bearing) . If an arrow is cast, it shall point towards the oil dipstick . Tightening torque for the main bearings : 1st tightening 20 N m (2 kpm) (14 .7 ft .lb), 2nd tightening 60 Nm (6 kpm) (44 .2 ft .lbs) . Turn the engine . 4 .
Install the main bearing halves in the oil pan and coat the edge of the oil pan with thin layer of sealing compound p/n 840879 . Install the oil pan and tighten the oil pan screws and the main bearing screws alternatingly to 20 Nm (2,0 kpm) (14 .7 ft .lbs .) and then the main bearing screws to 60 Nm (6,0 kpm) (44 .2 ft .lbs .) .
