Before installing the piston and connecting rod, make sure you put on the piston rings and dip the piston and its rings in oil. Adjust the ring compressor above the piston and rings so the rings stay in the right spots. Later, fit the bearing onto the connecting rod, so that the lubrication holes line up, then lubricate that part with clean engine oil. Screw the Connecting Rod Guides 8507 onto the bolts of the connecting rods after placing the bolts into the cylinder head holes. Each piston has an "F" symbol raised on the face of the piston bore and both must be faced toward the engine's front; the connecting rod oil slinger slot also needs to be pointed this way. Carefully clean the cylinder insert and spread clean engine oil on it. Turn the
Crankshaft so that the connecting rod journal is exactly centered in the bore, then put the rod and piston into the bore and place the connecting rod guides onto the crankshaft journal. Hold the connecting rod over the rod journal as you tap down the piston with a hammer handle. You should always change the connecting rod bolts when they become loose or need to be taken out. Apply engine oil to the fresh bolts and the connecting
Rod Bearings, fit the cap and only the main bolt with a length to 27 Nm plus 90°. Once all other steps are finished, set the cylinder head(s),
Timing Chain and cover, cylinder head covers and
Oil Pan with gasket/windage tray, add the engine oil up to the correct level in the crankcase and attach the negative cable to the battery.
