A4 1 8 turbo (150 koni)

~T. tnsure timing mark angned [bj.

2.    Fit timing belt to crankshaft sprocket and auxiliary shaft sprocket.

NOTĘ: If leusing old belt: OI>seive diiection of lotation maiks on belt.

3.    Install:

o Timing belt lower cover [9]. o Crankshaft pulley [3]. 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].

3. Fit two-pin wrench [13], Tool No.Matra V.159.

NOTĘ: Two-pin wiench iocates in hole [1G] and against Ing [17J. When tuming two-pin wiench clockwise. the tensionei pulley will turn anti-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].

13.    Check alignment of tensioner lever [14] [C] in relation to upper edge of piston [14] [B] as follows:

o [14] [D] - adjustment correct, o [14] [E] - wear area, re-adjust.

° I¹⁴) IN • 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: After instaliation, conect adjustment is maintained pioviding 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)
