Stress - Free Alignment of Exhaust System

^ The exhaust system must be aligned when cold.





^ As a tool for aligning the exhaust system, modify an M10 bolt according to the dimensions given.
- Dimension - x - = 4 mm
- Dimension - y - = 25 mm

Notes: Two technicians are required to align the exhaust system.

^ Loosen bolted connections on clamp.





^ Insert modified bolt (aligning tool) through rear drilling - arrow - in tunnel cross - piece, with flat part of bolt facing toward mounting pin on exhaust system.

Notes: With bolt inserted, exhaust system is pro - tensioned in the direction of travel.





Vehicles with front wheel drive
^ Align catalytic converter horizontally - C - and make sure that gaps - A - and - B -between catalytic converter and tunnel are equal.





Vehicles with all wheel drive
^ Align catalytic converter horizontally - 4 - and make sure that gaps - 3 - between catalytic converter and heat shield in tunnel - 2 - are equal.

All vehicles
^ Align front and rear silencers horizontally.





^ Mounting pin on exhaust pipe must be parallel to tunnel cross - piece (dimension - x - must be the same on left and right).





Aligning tailpipe in bumper cut - out
^ Align rear silencer so that gaps - a - and - b - between silencer and bumper cut - out are equal. To do this, it may be necessary to loosen the rear silencer mounting.
^ On vehicles where the exhaust has been cut through between the front and rear silencers, it may be necessary to loosen the clamp in order to achieve proper alignment.





^ Install sleeve clamps so that the screws are at right and the screw ends do not project out over the lower edge.





^ Position each clamp at a distance of about 5 mm from the notched markings. Arrange horizontally, then tighten evenly to 40 Nm.

The bolted connections on the clamp point to the left.
