INSTALLATION






1.Install gasket between turbocharger and catalyst as shown in the figure.





2.Install catalyst converter with the following procedure.





- Tighten in numerical order as shown in the figure.
- Install catalyst converter (base on stud position 1).
- Temporary assemble 2 (no priority).
- Temporary assemble 3, 4.
- Tightening 5, 6 and 7.
- Tightening again 8, 9 and 10.
- Temporary assemble 11.
- Tightening 12,13,14,and 15.
