Information:

Cylinder Block, Cylinder Liners, and Cylinder Head
The cylinder block has cylinders which are arranged in-line. The crankshaft of the six cylinder engine has seven main bearings. The thrust bearings on the main bearing journals control the end play of the crankshaft.A cylinder sleeve is available as a replacement. Replace the cylinder sleeve if a sleeve is worn or if a sleeve is worn in excess of the service limit. Set up a boring bar on the cylinder block. Bore the cylinder sleeve to 0.5 mm (0.02 inch) of the original thickness. Remove the remainder of the cylinder sleeve with a hammer and punch. Install the cylinder sleeve in the bore of the block with the appropriate tooling. Bore the sleeve and hone the sleeve to a diameter of 102.00 to 102.04 mm (4.016 to 4.017 inch).A cylinder head gasket is used between the plate and the head in order to seal combustion gases, water, and oil.The engine has a cast cylinder head. An inlet valve and an exhaust valve for each cylinder are controlled by a pushrod valve system.Pistons, Rings, and Connecting Rods
The cast aluminum piston has three rings: two compression rings and one oil control piston ring. All rings are located above the bore of the piston pin. The two compression rings sit in a cast iron insert.The oil control piston ring is a standard type and the oil ring is spring loaded. Oil returns to the crankcase through holes in the groove of the oil control piston ring.The direct injection piston has a full skirt. The direct injection piston uses a special shape on the top surface in order to help combustion efficiency.The full floating piston pin is retained by two snap rings. The two snap rings fit in grooves in the pin bore.Piston cooling jets are located on the main webs of the cylinder block. The piston cooling jets direct oil in order to cool the piston components and the cylinder walls. The piston cooling jets also direct oil in order to lubricate the piston components and the cylinder walls.Crankshaft
The crankshaft changes the combustion forces in the cylinder into usable rotating torque in order to power the machine. Vibration is caused by impacts from combustion along the crankshaft.A gear at the front of the crankshaft drives the timing gears. The gear also drives the oil pump.Pressurized oil is supplied to all bearing surfaces through drilled holes in the crankshaft.Lip type seals are used on both the front of the crankshaft and the rear of the crankshaft.Camshaft
The engine has a single camshaft. The camshaft is driven at the front end. Bearings support the camshaft. As the camshaft turns, the camshaft lobes move the valve system components. The valve system components move the cylinder valves. The camshaft gear must be timed to the crankshaft gear. The relationship between the lobes and the camshaft gear causes
