Engine, description (Deutz D6D EBE2)
The engine is a 6–cylinder, 4–stroke, direct injected, turbocharged, aftercooled with a cast iron block and cylinder head.
Gears in the engine gear case are hardened helical type for strength and reduced noise, arranged to provide quiet, smooth
transmission of power.
The cylinder block and head are designed with internal passages forming galleries for both lubricating oil and coolant.
The fan belt is a poly type V-belt for improved performance and an auto tension adjuster maintains belt tension.

211 Service Information 2015/3/12
Profile:
EXC, EC180B LC [GB]
Determining cylinder head gasket


The thickness of the cylinder head gasket is responsible for the correct piston crown clearance of the engine. The
piston crown clearance (0.65 mm) essentially influences the combustion and thus:



Power
Fuel consumption
Exhaust emission
The piston crown clearance is adjusted by determining the piston projection and the thickness of the cylinder head
gasket.
Measuring piston projection


A dial gauge with a fixture is needed to measure the piston projection.
The piston is in its TDC position above the cylinder block face.

Set the dial gauge on the level of the cylinder block face to “zero”.
Position the dial gauge at measuring points (C), at the piston pin axis on the piston and determine the
maximum projection.
Measuring points on the piston.
Distance X = 90 mm
This measurement is performed on each piston. The maximum measured piston projection determines the thickness of the
cylinder head gasket (see table). There are 3 different gasket thicknesses identified by bores (4):



1 bore = 1.2 mm
2 bores = 1.3 mm
3 bores = 1.4 mm
