Crankshaft characteristics (petrol engines 1.4 and 1.6 l, EPZ, TU5) (Peugeot 207)

Crankshaft

Cylinder Block / Crankshaft Marking (1.4L engine)

Marking area (E):

• letters denoting the code (five letters allow you to identify the inserts that need to be installed);
• the first letter indicates the root neck according to No.1;
• an arrow that indicates the direction of rotation of the timing mechanism.

Zone (A):

• letters denoting the code (five letters allow you to identify the inserts that need to be installed) (WITH);
• the first letter indicates the root neck according to No.1;
• the arrow indicates the timing mechanism drive side.

Zone (B): Barcode used in the factory.

Zone (D): marking zone - engine type.

Ensuring the pairing of crankshaft journal liners (1.4L engine)

• Class A: Blue Label.
• Class B: orange label.
• Class C: Black Mark.
• Class D: yellow mark.
• Class E: green label.
• Class G: White Mark.

Bearing cap side (example): If the first letter in the crankshaft marking is S and in the cylinder block marking is E, the main bearing bearing on the side of the main bearing cap No.1 must be class B (color: orange).



Cylinder Block Side: Upper Bearing (from the cylinder block side) must always be class C (color: black).

Ensuring the pairing of crankshaft journal liners (1.6L engine)

• Class A: Blue Label.
• Class B: Black Mark.
• Class C: green mark.

Bearing Cap Side (Example): If the first letter in the crankshaft marking is S and in the cylinder block marking is E, the main bearing bearing on the side of the main bearing cap No.1 must be class A (color: blue).

Cylinder Block Side: Upper Bearing (from the cylinder block side) must always be class B (color: black).

Inserts

The colour mark (C) allows identification of the liner class.

Characteristics

The thrust half rings for adjusting the side clearance are indicated in the figure by the number (1). The main journal liners 2 and 4 have grooves.



Side shim thickness (crankshaft): (G) 2.40/2.50/2.55/2.60 mm.

Attention: Make sure the inserts are installed correctly.

Main journals 1-3-5: smooth bearings (from the cylinder block and bearing cap side). Main journals 2 - 4: grooved bearings (from the cylinder block and bearing cap side).

Note: Oversize main journal bearings are stamped on the R side of the main journal cap.

Dimensions of 1.4L engine liners

* Letter R stamped on the back of the insert.

Dimensions of 1.6L engine liners

* Letter R stamped on the back of the insert.

• Class A (initial size) becomes class U (repair thickness).
• Class B (initial size) becomes class V (repair thickness).
• Class C (initial size) becomes class W (repair thickness).
• Class D (initial size) becomes class X (repair thickness).
• Class E (initial size) becomes class U (repair thickness).
• Class G (initial size) becomes class Z (repair thickness).

Main journals 1-3-5: smooth to bearings (from the cylinder block and bearing cap side).



Main journals 2 - 4: grooved bearings (from the cylinder block and bearing cap side).

Note: Oversize main journal bearings are stamped on the R side of the main journal cap.

• Class A (initial size) becomes class Z (repair thickness).
• Class B (initial size) becomes class U (repair thickness).
• Class C (initial size) becomes class X (repair thickness).

Attention. Boring of connecting rod and main journals requires subsequent polishing operation.
