This document provides instructions for removing an engine from various models including the MC80B, MC90B, and MC110B. It is a multi-step process that involves draining fluids, disconnecting hoses and electrical connections, removing mounting hardware, and then using an overhead lift to remove the engine. Safety precautions are provided regarding hot fluids and ensuring stable support of heavy engine components during removal.

Engine for MC80B, MC90B and MC110B, description
The engine is a vertical in-line, four cylinder, four stroke, water-cooled diesel engine with a direct injection system. The
engines for MC90B and MC110B are also equipped with a turbocharger of radial flow type. The valve mechanism receives its
movement from the camshaft via rods and rocker arms. Turning direction is counter-clockwise seen from the flywheel. Firing
order is 1-3-4-2 and the first cylinder is on the flywheel side.
The fuel system is direct injection via a rotary high pressure pump, a so called MP pump. The pump has only one plunger
cylinder to pressurize the fuel and a distribution shaft which regulates the fuel flow to each cylinder.
The lubrication system consists of forced lubrication with a trochoid pump.
The air system consists of a dual element, self cleaning air cleaner.
The cooling of the engine is performed by a high capacity radiator and a hydraulic oil cooler. The type of fluid used in the
cooling system consists of 50% ethylene glycol and 50% water, which gives an anti-freeze protection.

mechanism receives its movement from the camshaft via rods and rocker arms. Turning direction is counter-clockwise seen
from the flywheel. Firing order is 1-3-4-2 and the first cylinder is on the flywheel side.
The fuel system is fed by an electric fuel pump that supplies the fuel to the electronic fuel injection pump.
