Internal combustion engine and lubrication system thereof

An internal combustion engine for a vehicle, the engine comprising:

• a crankcase;
• a crankshaft disposed at least in part in the crankcase;
• a cylinder block connected to the crankcase, the cylinder block defining at least one cylinder;
• at least one piston operatively connected to the crankshaft and disposed in a corresponding one of the at least one cylinder;
• an oil tank defining an oil reservoir configured to contain oil therein;
• and
• a dry-sump lubrication system comprising a pump module for circulating oil throughout the engine, the pump module comprising an outer flange rotatably connected to the pump shaft and fastened to the crankcase to secure the pump module in place, the pump module comprising:
• a pump shaft rotatable about a pump shaft axis;
• at least one pressure pump mounted to the pump shaft and configured to pump oil from the oil tank;
• and
• at least one scavenge pump mounted to the pump shaft and configured to draw oil from a respective part of the engine.
