    Mitsubishi 4G63 and 4G64 forklift engines

    The 4G63 and 4G64 are Mitsubishi's 2.0 and 2.4 liter industrial spark-ignition engines, fitted to gas and LPG lift trucks under several brands. They share an architecture, iron block and aluminum head on a belt-driven camshaft, but every part set by displacement differs. Read the stamped engine number rather than the family designation, and confirm the fuel system separately.

    The Seven OSHA Forklift Classes

    Every powered industrial truck falls into one of seven OSHA classes, sorted by power source, tire type and how the operator works the machine. Classes I–III are electric, IV and V are internal combustion on cushion and pneumatic tires, VI covers tractors and tow vehicles, and VII is rough terrain. The class tells you where a truck can run and which parts it consumes.

    Forklift Drum Brakes: How They Work, What Fails and How to Diagnose It

    Most internal combustion forklifts stop on drum brakes at the drive axle: one master cylinder feeding a wheel cylinder at each end, spreading two shoes against a drum. The shoes self-adjust, but on most designs only when the truck brakes in reverse. Three quarters of brake complaints come down to contaminated linings or adjustment, not worn parts.

    Forklift Cooling Systems: How They Work, What Fails and How to Diagnose It

    A forklift cooling system is a pressurised loop of water and antifreeze moved by a belt-driven water pump, regulated by a wax-pellet thermostat and cooled by a fan through the radiator. On powershift trucks the same radiator also cools transmission oil, so overheating is a whole-truck problem. The radiator cap holds pressure to raise the coolant's boiling point — a weak cap causes overheating on its own.

    Forklift Carburetors: How They Work, What Fails and How to Adjust Them

    A carburetor meters fuel into the engine's airflow using calibrated jets and mechanical linkage, with no sensors or feedback. Separate circuits handle idle, main running, full load, sudden acceleration and cold starting, all working from one constant fuel level in the float bowl. On a forklift the throttle pedal commands a governor, not the carburetor directly, and coolant is routed through the casting to stop the throttle plate icing.
