3.    Install:

o Timing belt lower cover (9). o Crankshaft pulley [8]. o Crankshaft pulley bolts (7).

4.    Lightly tighten crankshaft pulley bolts (7).

5.    Ensure timing mark on crankshaft pulley aligned [6].

6.    Fit timing belt to tensioner pulley and camshaft sprocket.

7.    Slacken tensioner bolt (10).

8.    Fit two-pin wrench (13). Tool No.Matra V.159.

NOTĘ: Two-pin wiench locates in hole [1G] and against Ing [17J. Wlien tuining two-pin wrench clockwise. the tensioner pulley will turn a nti-clockwise and apply tension to belt.

9.    Tum two-pin wrench clockwise (15) until piston (14) (A) is fully extended and piston (14) (B) has risen approximately 1 mm.

10.    Lightly tighten tensioner bolt (10).

11.    Turn crankshaft two turns clockwise.

12.    Ensure timing marks aligned (5) & (6).

o (14) (D) - adjustment correct, o (14) (E) - wear area, re-adjust. o (14) (F) - check tensioner and re-adjust.

14.    When adjustment correct, dimension (14) (G) will be 25-29 mm.

15.    If alignment incorrect or dimension (14) [G] not as specified: Repeat tensioning procedurę.

NOTĘ: Aftei instaiiation, correct adjustment is maintained providing upper edge of piston [14] [B] is positioned within areas [14] [D] and [14] [EJ.

16.    Tighten tensioner bolt to 25 Nm (10).

17.    Tighten crankshaft pulley bolts (7). Tightening torque:

o Class 8.8 = 10 Nm + 90° Use new bolts. o Class 10.9 = 40 Nm.

(A4 - 45 Nm) (A5 - 50 Nm)
