    Guides for this model

    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.

    Nissan K21 and K25 Engines Explained

    The K21 and K25 are four-cylinder industrial engines sharing an 89 mm bore and differing in stroke, at 2,065 cc and 2,488 cc. Both use an overhead-valve pushrod valvetrain with a rocker shaft and screw adjusters, a bathtub combustion chamber, a timing chain, five main bearings and a chain-driven side power take-off. Both run gasoline or LPG.

    Nissan K21 and K25 Maintenance and Troubleshooting

    Routine service on a K21 or K25 covers valve clearance set hot at 0.38 mm on every valve, a cold retighten of the head bolts and manifold nuts, belt deflection, oil and filter, plugs, air and fuel filters and coolant. Most running complaints trace back to compression, ignition or fuel, and a compression test separates them quickly.
