Information:

The regulator valve is mounted at the lower portion of the injection pump on the left side of the crankcase. It regulates pressure of engine oil that flows through the oil filter and oil cooler into the main gallery.When oil pressure in the main gallery exceeds specified level the regulator valve opens to return part of engine oil to the oil pan.(5) Lubrication of All PartsThe engine oil routed to the main oil gallery lubricates all parts as described in the following.(a) Main bearing and connecting rod bearing The oil main gallery connects to the crankshaft main bearing through oil holes for lubrication of the main bearing. Part of engine oil that has lubricated the main bearing flows through the oil
