B1BJ0LK1 - 206 TU ENGINE

MATCHING MAIN BEARING SHELLS (ENGINE WITH IDENTIFICATION)

There are 2 different cases :

- engine with identification
- engine without identification, ENGINE REWORKED OR FITTED WITH A REGROUND CRANKSHAFT

Markings on the cylinder block and crankshaft enable matching .

1 - ENGINE IDENTIFICATION

Zone A :

- code reference letters (five letters to identify the shells to be fitted)
- the first letter indicates no.1 bearing
- the arrow indicates the timing gear end

Zone B :

- bar code used in plant

2 - IDENTIFICATION (HALF SHELLS)

A paint mark at (C) identifies the grade .

3 - MATCHING TABLE

3 - 1 - CAST-IRON CYLINDER BLOCK

Category (A) : Blue marking .

Category (B) : Black identification mark .

Category (C) : Green marking .

Half shells, Bearing cap .

Example : if the first crankshaft letter is (S) and the cylinder block (E) :

- the half shell on the main bearing cap no. 1 side will be of grade (A) (colour : blue)

Cylinder block shells :

- the half shell on the cylinder block side will always be grade (B) (colour : black)

IMPERATIVE : the half shells must be fitted in the correct locations .

Bearings 1 - 3 - 5 = smooth shells (cylinder block and bearing caps) .

Bearings 2 - 4 = grooved shells (cylinder block and bearing caps) .
