Oil sump - specified torques and installation sequence 1.  Tighten the bolts -1 … 18- to 5 Nm crossways. 2.  Tighten sump/gearbox bolts: 45 Nm. 3.  Tighten bolts M10 -arrows- to 40 Nm. 4.  Tighten the bolts -1 … 18- diagonally to 15 Nm. –  Tighten bolts in 3 stages:

stage:	Bolts	Tightening torque
1.	-1 … 20-	5 Nm in diagonal sequence
2.	-Arrows -	40 Nm.
3.	-1 … 20-	Tighten in stages and in diagonal sequence; final torque 13 Nm.

Installation position of thrust washer   Caution When installing the idler wheel, take care that the thrust washer -A- does not slip from the journal of the balance shaft assembly -arrows- and does not block. If necessary, fix the assembly using lubricant.

Balancer shaft module - specified torques and sequence   Note Renew the bolts tightened with specified tightening angle. –  Tighten bolts securing balance shaft assembly as follows:

stage:	Bolts	Tightening torque/angle specification
1.	-1 … 6-	Screw in hand-tight in this sequence
2.	-1 … 6-	Pre-tighten bolts in this sequence to 6 Nm
3.	-1 … 4-	Tighten with 20 Nm
4.	-5 and 6-	Tighten with 13 Nm
5.	-1 … 6-	Use rigid wrench to turn 90° further in this sequence
