Tools marked with * are components of the timing chain tool set (MH063679). [Inspection] • Perform the following inspections. If there is any abnormality, replace the timing chain. (1) Noise • Run the engine and check for any abnormal noise caused by interference between piston and valve. • If abnormal noise is heard, check the… Read More »
• Valve clearance should be checked and adjusted as follows while the engine is still cold. [Inspection] • Remove the rocker cover. • Bring the No. 1 or No. 4 cylinder piston to the top dead center (TDC) on the compression stroke according to the following procedure: • Rotate the crankshaft pulley in the illustrated… Read More »
•For the hybrid electric vehicle system, there are two methods of cranking the engine, a conventional method using the starter and a method using the motor of the hybrid electric vehicle system. • If the engine is cranked with the motor of the hybrid electric vehicle system, measurement of compression pressure may become inaccurate since… Read More »
10.1 Front oil seal • The front oil seal is fitted in the timing gear case, and prevents oil from leaking by contact of its lip with the crankshaft pulley. 10.2 Rear oil seal • The rear oil seal is fitted in the rear oil seal case, and prevents oil from leaking by contact of… Read More »
9.1 Crankcase • The crankcase is a bi-block type consisting of an upper crankcase and a lower crankcase that are assembled to grip the crankshaft in between. • The upper crankcase has cylinders whose surfaces are machined for direct contact with sliding pistons. The walls of the cylinders have water jackets for cooling the cylinders.… Read More »
• The bearing is fitted into the flywheel and held in place by the washers. • The peripheral edge on one side of the ring gear is chamfered for easy engagement of the gear with the starter pinion.
•For selective fit of the pistons with the upper crankcase, match corresponding size marks on the pistons and upper crankcase. The size marks of the pistons are “A” through “C” and the “C” marked piston has the largest outside diameter. • Install the pistons with the front marks facing forward of the engine.
• The “F” mark indicates the assembly direction onto the piston and engine front side. • The color mark indicates the diameter class of the large end.
•Each timing gear has mating mark(s) “1” or “5” to ensure that it is engaged correctly with another gear during installation. 5.1 Idler gear • The idler gear is press fitted into the idler sprocket, which drives the timing chain, and rotates on the idler shaft. • The idler shaft is anchored to the crankcase… Read More »
