   *2	Gasket
   *a	1.5 mm (0.0591 in.) or less
   *b	Knock Pin

   NOTE:

   When reusing the converter assembly RH, thoroughly clean the gasket groove so that no old gasket remains.

   HINT: 

   Fully insert the gasket into the gasket groove of the converter assembly RH.

2. Set a new exhaust pipe clamp RH to the converter assembly RH.
   NOTE:

   Make sure the end of the exhaust pipe clamp RH does not open 140 mm or more (standard amount approximately 60 mm).

3. Temporarily install the manifold stay to the converter assembly RH with the nut.
   NOTE:

   Tighten the nut by hand until it contacts the surface.

4. Align the converter assembly RH with the knock hole on the No. 1 turbocharger sub-assembly side to connect the converter assembly RH.
   NOTE:

   Make sure that there is a knock pin on the converter assembly RH.

5. Tighten the nut.

   Torque: 43 N.m (438 kgf/cm, 32 ft.lbf)
