Exhaust manifold
To remove/replace the exhaust manifold:
1. Remove the muffler by following the procedures
described in the previous section.
2. Remove the manifold screws using a 10 mm
wrench. See Figure 8.3.
3. Clean the cylinder head and muffler of any residual
gasket material.
NOTE: The exhaust gasket is made of a graphite
material. It will stick to the sealing surfaces
when pressure is applied, tearing when
pressure is relieved. The gasket can only be
used one time.
4. Using a new gasket, install the manifold by following
the above steps in reverse order.
NOTE: Tighten the manifold screws to a torque of
80 - 106 in-lbs (9 - 12 Nm).
5. Test run the engine before returning to service.
