Exhaust System, Aligning Free of Stress



Exhaust System, Aligning Stress-free

- The exhaust system must be aligned when cold.







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

NOTE: 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.

NOTE: With bolt inserted, exhaust system is pre-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 mufflers horizontally.







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







Aligning tailpipe in bumper cut-out

- Align rear muffler so that gaps -a- and -b- between muffler and bumper cut-out are equal. To do this, it may be necessary to loosen rear muffler mounting.

NOTE: On vehicles where the exhaust has been cut through between the front and rear mufflers, it may be necessary to loosen the clamp in order to achieve proper alignment.







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







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

Bolted connections on clamp point to left.
