Tightening torques
  Note
t  Tightening torques apply only to lightly greased, oiled, phosphated or black-finished nuts and bolts.
t  Additional lubricants such as engine or gearbox oil may be used, but do not use lubricants containing graphite.
t  Do not use de-greased parts.
t  Tolerance for tightening torques: ± 15 %.

l  1) Also secures starter.
l  2) Property class 10.9. The steel bolt may be re-used as often as necessary.
l  3) Aluminium bolts must not be used more often than twice → Anchor.

   
t  The aluminium bolts -2 … 11- must not be used more often than twice. After the first use, the bolts must therefore be identified with an „X“ made by two chisel marks -arrow-.
t  To avoid damaging the bolts when making this mark, do not clamp them directly in a vice. Clamp a 14 mm socket with 1/2" drive in a vice and insert the bolt as shown.
t  Bolts already marked with an „X“ must not be used again.
Procedure
  Note
t  Renew the bolts tightened with specified tightening angle.
t  Renew self-locking nuts and bolts as well as seals, gaskets and O-rings.
t  Hose connections and air pipes and hoses must be free of oil and grease before assembly.
t  Secure all hose connections with the correct type of hose clips (same as original equipment) → Electronic parts catalogue.
t  Fit all cable ties in the original positions when installing.
–  Before installing gearbox, remove residue from threaded holes for engine/gearbox bolts in cylinder block using a thread tap.

  A13-0763
–  The following preparations are required before joining engine and gearbox.
–  Insert assembly aid -T40169- into gearbox housing and clutch module from below, as illustrated.
l  The assembly aid must engage in the semi-circular recess -1- and in the inspection hole -2-.
  Note
There is only one inspection hole on the circumference; turn the clutch module accordingly.
–  Insert pin of assembly aid into hole on gearbox housing.
  A10-10825
–  Insert transport lock -T40170- into gearbox housing from below and clamp onto flange shaft -1-.

  A10-10826
–  Check whether dowel sleeves -A- for centring engine and gearbox are fitted in cylinder block; install missing dowel sleeves.
–  Check whether aluminium bolts securing engine to gearbox can be reused; if so, apply marking → Anchor.
–  Bring gearbox into position on engine and tighten bolts -1 … 10-.
–  Remove transport lock -T40170- and assembly aid -T40169-.
–  Install engine supports and engine mountings → Chapter.
  Note
  A34-10471
The following step is necessary to ensure that the clutch module is straight and that it makes even contact with the drive plate.
–  Use assembly lever -1- to press clutch module -2- slightly against drive plate -3- in direction of -arrow-.
  A34-10497
–  Bolt clutch module onto drive plate as follows:
  Note
Use ring spanner insert AF 16 -V.A.G 1332/14- to tighten bolts.
–  Hand-tighten first bolt -arrow- (2 Nm).
  A10-10629
–  Fit adapter -T40257- onto wrench -T40263-.
–  Position adapter on bolts of vibration damper.
l  The semi-circular recess -arrow A- on the adapter -T40257- must point to the semi-circular recess -arrow B- on the vibration damper.
  Note
Disregard notch on adapter -T40257-.
–  Turn crankshaft 180° in direction of engine rotation -arrow-.
–  Tighten bolt accessible in this crankshaft position to specified torque → Rep. gr.34.
–  Turn crankshaft by 60° each time and tighten remaining 5 bolts to specified torque → Rep. gr.34.
–  Install hydraulic lines for power steering → Rep. gr.48.
–  Bolt drive shafts (left and right) onto gearbox flange shafts → Rep. gr.40.
