EB2L direct injection engine : The crankshaft, made of forged steel, is non-repairable.

2.1. References on crankshaft

The diameter values for the main journals and crank pins are referenced on the crankshaft (at "e", "f") (Flywheel side).

"e" Record of the value of the main journals (Machined surface) - Alphabetical characters.

"f" Record of the value of the crank pins (Machined surface) - Alphabetical characters.

N.B. : Direction of reading from the flywheel towards the timing.

Components "e"	Main journal bearing n°
O	1
L	2
M	3
M	4

N.B. : Bearing n°1 flywheel end (Cylinder no 1).

Components "f"	Crank pin bearing n°
J	1
H	2
H	3

N.B. : Bearing n°1 flywheel end (Cylinder no 1).

2.2. Crankshaft measurements

engine	EB2LTD / EB2LTED / EB2LTDH2 / EB2LTEM
"C" Nominal diameter of the main journal	42 (0 ; -0,016) mm
"D" Nominal diameter of the crank pin	42 (0 ; -0,016) mm

2.3. Measurement of the diameter of the main journals

N.B. : Journals (3).

Components	Measurement	Values
"E"	Measuring zone	10 mm
"F"	Angle between each diameter	120°
"G", "H", "J"	Measurement diameters	-

Calculation of the diameter of the main journal "C" :

• ØG = (ØG1 + ØG2 + ØG3) / 3
• ØH = (ØH1 + ØH2 + ØH3) / 3
• ØJ = (ØJ1 + ØJ2 + ØJ3) / 3

Diameter of the main journal "C" : ØC = (ØG + ØH + ØJ) / 3.

N.B. : The method for measuring the diameter "D" of the crank pins is identical.

3. Crankshaft bearing shells

CAUTION : Do not invert the crankshaft shells and big end shells of the EB2L engines (The diameter of the bearings is identical, but the thickness and part number of the shells are different).

CAUTION : The crankshaft shells have only one colour marking (at "j").

CAUTION : Only the crankshaft lower half-shells (5) are classed.

The upper half-shells (4) are different :

• Bearings number 1 and 4 : Partially grooved half-shells (at "g")
• Bearings number 2 and 3 : Fully grooved half-shells (at "h")

The lower half-shells are identical, smooth, and are available in 4 thicknesses.
