HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
- Make sure that SST and a wrench are connected in a straight line.
2. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Check the compression springs.
(1) Check the compression springs using vernier calipers
Specified length: 38.86 mm (1.5299 in.)
HINT: If the result is not as specified, replace the compression spring.
(b) Install the gasket.
(1) Install a new gasket by hand onto the front exhaust pipe assembly.
(2) Using a plastic hammer and wooden block, tap in the new gasket until its surface is flush with the front exhaust pipe.
