Fig. 10 – Diagram of the Cooling System

The thermostat with solid filler serves to speed up the engine warming-up after starting it

and automatic regulation of the temperature regime at various loads and ambient temperatures.

The water pump, fan and alternator are driven from the engine crankshaft pulley by

means of a V-belt. On the D-245 engine these units are driven by means of two belts.

The "Litol-24" lubricant is injected into the bearing cavity of the pump during the assem-

bling. The pump bearings need not lubrication for the whole period of operation of the diesel en-

gine.

The cooling system of the engines equipped with starting engines is connected with the

cooling system of the starting engine. The cooling jacket of the starting engine cylinder communi-

cates with the cooling jacket of the diesel engine cylinder head and the cooling jacket of the cylin-

der head of the starting engine communicates with the housing of the diesel engine thermostat.

1.2.2.7. Lubricating System

The diesel engine has a combined lubricating system. The bearings of the crankshaft and

camshaft, bushes of the intermediate gear and fuel-pump driving gear, the connecting-rod bearing

of the air-compressor crankshaft, as well as valve driving gear and on the D-245 engine also the

turbo-supercharger shaft bearing, in accordance with Fig. 11, are lubricated under pressure. The

sleeves, pistons, piston pins, push rods, pushers and cams of the camshaft are splash lubricated.

The oil pump 12 is a gear-type, single-section one bolted to the first main bearing cover.

The pump delivers oil via pump outlet pipe and cylinder block channels to the centrifugal filter 3,

where it is cleaned from foreign particles, combustion and wear products. Cleaned oil is trans-

ferred from the centrifugal oil filter to the radiator for cooling, and, on the D-245 engine, addi-

tionally to the turbo-supercharger shaft via oil duct. The oil is transferred from the oil radiator in-

to the diesel main pipelines.
