CRANK SHAFT FITMENTThe crankshaft, sometimes casually abbreviated to crank, is the part of an engine which translates reciprocating linear piston motion into rotation

CAM SHAFT FITMENTA camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.

GEAR CASING FITMENTA gear is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part in order to transmit torque. Two or more gears working in tandem are called a transmission and can produce a mechanical advantage through a gear ratio and thus may be considered a simple machine

CRITICAL AREA PISTON ASSEMBLY

In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod

CYLINDER BLOCK FITMENTThe cylinder block or engine block is a machined casting (or sometimes an assembly of modules) containing cylindrically bored holes for the pistons of a multi-cylinder reciprocating internal combustion engine, or for a similarly constructed device such as a pump

OIL SUMP FITMENTOIL SUMP IS USED TO STORE THE LUBRICATING OIL WHICH IS SUPPLIED FOR LUBRICATION TO DIFFERENT ENGINE PARTS THROUGH SUCTION TUBE.

CYLINDER HEAD FITMENTIn an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It consists of a platform containing part of the combustion chamber (usually, though not always), and the location of the poppet valves and spark plugs

WATER PUMP FITMENT

WATER PUMP IS USED TO SUPPLY WATER IN DIFFERENT PARTS OF ENGINE FOR COOLING PURPOSE.

FIP FITMENTFUEL INJECTION PUMP IS USED TO SUPPLY THE FUEL FOR COMBUSTION.
