CRANKCASE AND CYLINDER SLEEVE 1.

Crankc Crankcase ase is manuf manufact acture ured d firmly with with cast iron iron to prevent stress concentration and deformation.

2.

The 5 camshaft camshaft b bushes ushes are install installed ed to the camshaf camshaftt bore of the crankcase. To facilitate the removal and installation of camshaft, inner diameter of bush is tapered to the rear side.

PISTON 1.

Piston pin type type is full float type and and piston piston pi pin n is offset from thrust.

2.

Marks on the the p piston iston indicat indicate e weight, weight, part number number and oversize. The front mark indicates the front direction of the engine. NOTE When assembling a piston, let the arrow mark ( →) faced to the center of cylinder head bolt hole.

OIL COOLER

REGULAT REGU LATOR OR VAL VALVE VE

Oil cooler is equipment for heat exchange between the coolant and oil fed from the crankcase water jacket and oil pump, respectively. The oil cooler has a bypass valve that opens when the element (1) becomes clogged.

When oil pressure in main oil gallery exceeds the specification, regulator valve (1) opens and some engine oil drains to the oil pan to adjust the oil pressure.

SUDEM7232L SUDEM7230L

OIL PRESSURE SWITCH

BYPASS VALVE VALVE When the oil viscosity is high (in cold) or oil path shows high resistance depending on the element load, the bypass valve (1) opens and oil goes directly to oil filter without passing oil cooler.

If the pressure of engine oil which is sent to the main oil gallery is below the specificat specification, ion, the built built-in -in relay in the oil pressure switch (1) is closed, then the warning lamp in the instrument panel is on to inform the driver of abnormal pressure.

WATER WA TER PUMP Water ater pump pump,, a cent centrif rifug ugal al type type,, is dri drive ven n by the VV-bel beltt from from the crankshaft pulley. A unit seal is installed between impeller and water pump that prevents leakage of coolant. There is a drain hole provided at the bottom of the water pump case, which ensures that water should leak from the unit seal, does not enter bearings. The water pump is mounted on the timing gear case provided with a suction pipe and swirl chamber. An Impeller, pressed fit into the one end of water pump shaft, has the combination blade, which feeds coolant under pressure into the engine.

A jigg jiggle le valv alve is inst instal alle led d in the the air air plug plug hole hole of ther thermo mo-stat, which heats up the coolant temperature rapidly to put the engine temperature to the normal one. When engine stops, and coolant flows as jiggle valve falls down by its weight so that air in the engine is led to radiator through the cleara clearance nce between the jiggle valve and the breather hole. When the engine starts, coolant flow into the radiator and jiggle valve is pushed up by the water pressure. As a result, valve covers the air plug hole to prevent the coolant from leaking through the hole.

RADIATOR The radiator radiator,, which consists of tube-and-corruga tube-and-corrugated-fi ted-fin n type typ e core, core, not only cools the engine engine coolant coolant but also also separates vapor from liquid water and regulates pressure in the cooling system.

2.

Since Since the fluid (silic (silicon on oil) ke keeps eps flo flowing wing,, viscos viscosity ity between the coupling case and rotor increases, and the fan mounted to the case has the similar speed of shaft. Viscosity Viscosity varies varies with the fluid amount (silicon oil).

RADIATOR RADIA TOR CAP Radiator cap regulates the pressure in the cooling system. When the pressure exceeds the predetermined level, the pressure valve compresses the pressure spring to release the excessive pressure to the air. As the coolant temperature drops and forms a vacuum in the radiator radiator,, the vent valve opens to admit air into the radiator, thus preventing the radiator from being deformed by the vacuum.
