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.
