2-3 JIV11001 ENGINE M MECHANISM AND FUNCTION 1 . General The Subaru 3300cc, 6-cylinders engine is made from aluminum alloy and is horizontally opposed . It is a 4-stroke cycle, water-cooled, DOW 24-valve engine . The fuel system utilizes an MPFI (multiple fuel injection) design . A summary of the major construction and function features is given be[...]

ENGINE [nn2ool 2-3 2 . Timing Belt A single timing belt drives two exhaust camshafts (one in the left bank and one in the right bank) . The back of the belt also drives the water pump . The timing belt teeth have a specially designed round profile to provide quiet operation . The timing belt is composed of a strong and inflexible core wire, a wear-[...]

2-3 [M3001 ENGINE 3 . Belt Tension Adjuster The belt tension adjuster provides a constant value of tension for the timing belt . Proper belt tension is main- tained using a rod to push the tension pulley . The location of the tensioner pulley shaft center is offset in relation to the center of the pulley's outside diameter . The tensioner adju[...]

ENGINE [M500] 2-3 4 . Belt Cover The belt cover is made of synthetic resin molding which is lightweight and heat resistant . It has a totally enclosed design that utilizes rubber packing at the mating surface of the cylinder block . This eliminates the chance of dust and water from entering the interior . A floating design is utilized by placing ru[...]

2-3 [M600] ENGINE 6 . Hydraulic Lash Adjuster The hydraulic lash adjuster is located between the camshaft and valve stem . The top surface of the hydrau- lic lash adjuster is always in contact with the cam face . The cam directly pushes the lash adjuster to open or close the valve . The engine oil flows through the cylinder head and goes into the l[...]

ENGINE [Wool 2-3 7 . Cylinder Head Combustion chambers in the cylinder head are com- pact, center plug, pentroof types which feature a wide "squish" area for increased combustion efficiency . Four valves (two intake and two exhaust), which are arranged in a cross-flow design, are used per cylinder . The cylinder head gasket is made from c[...]

2-3 [M8001 ENGINE 8 . Cylinder Block The cylinder block is made from aluminum diecast . The cylinder perimeter has an open-deck design which is lightweight, highly rigid and has superb cooling effi- ciency . The cylinder liners are made from cast iron and are dry types which are totally cast with aluminum cylinder block . Seven main journal block d[...]

ENGINE [nn1ooo1 2-3 9 . Crankshaft The crankshaft is supported by seven bearings to pro- vide high rigidity and strength . The corners of the crankshaft journals and webs, as well as the crank pins and webs, are finished with fillet-roll work to increase strength . The seven crankshaft bearings are made from aluminum alloy and the No . 5 bearing is[...]
