5.3 Assembly
Assembly sequence: piston and connecting rod assemblies and crankshaftThe assembly sequence is indicated by the numbers in the drawing above. KEY POINTS FOR ASSEMBLY(1) Installing Main Bearings(a) Press the main bearings (upper and lower) into the cylinder block and main bearing caps, respectively, such that the bearings' lugs fit into the grooves.
Installing main bearings(b) Fit the flanged main bearing in the No. 3 journal position.(c) Smear a little engine oil on the inner surface of each bearing.
Installing flanged main bearing(2) Installing Crankshaft(a) Wash the crankshaft thoroughly in cleaning solvent, then dry it with compressed air.(b) Keeping the crankshaft horizontal, gently lower it into the cylinder block.(c) Smear a little engine oil on each crankshaft journal.
Installing crankshaft(3) Installing Main Bearing Caps(a) Before installing the main bearing caps, apply sealant to the mating surfaces of the frontmost and rearmost caps and to the corresponding surfaces in the cylinder block.
Installing main bearing caps(b) Referring to the cap numbers, fit the main bearing caps sequentially starting at the front of the engine. The arrow on each cap must point toward the front of the engine.
Make sure the frontmost and rearmost caps fit flush against the cylinder block.
Front marks and cap numbers(4) Tightening Bearing Cap BoltsTighten the bearing cap bolts alternately a little at a time, then torque each bolt to specification.
Tightening bearing cap bolts(5) Checking Crankshaft RotationConfirm that the crankshaft turns smoothly.
Checking crankshaft rotation(6) Measuring End Play of CrankshaftApply a dial gauge to the end of the crankshaft and measure the end play. If the measurement exceeds the specified limit, replace the No. 3 flanged bearing.
Unit: mm (in.)
Measuring end play of crankshaft(7) Inserting Side Seals(a) Apply sealant to the mating surfaces of each side seal. (b) With the radius of each side seal facing the outside, push the side seals part-way into the frontmost and rearmost caps by hand.
Alignment of side seals for installation(c) Press each side seal completely into position using a flat implement. Be careful not to bend the side seals.
Inserting side seals(8) Preparation for Installation of Piston and Connecting Rod Assemblies(a) Clean each cylinder's inner surface with a rag, then smear each with engine oil.(b) Press the connecting rod bearings (upper and lower) into the connecting rods and caps such that the bearings' lugs fit into the grooves.(c) Smear the connecting rod bearings with engine oil.(d) Turn the cylinder block onto its side.
Preparation for installation of piston and connecting rod assemblies(9) Preparation for Installation of Piston and Connecting Rod Assemblies(a) Smear the pistons' sliding surfaces and piston rings with engine oil.(b) Position the piston ring gaps as shown in the drawing. Do not align any ring gap with the piston pin or at 90° to the piston pin.
Piston ring positions(c) Turn the crankshaft until the crank pin onto which the connecting rod is to be fitted reaches its TDC position.(d) Align the piston such that its front mark (this is stamped on the piston crown) points toward the timing gear case mounting surface (the front of the engine).(e)
