Installation and Fitting Points:
The flange and exhaust pipe are flat seals, fastened with M10×35 bolts at a torque of 45–50 N·m, and fitted with a graphite composite gasket to prevent air leakage.

The lifting lugs are clearance-fitted to the vehicle body/frame spreader, positioned with Φ16 mm pins, and cotter pins are used to prevent them from falling off, avoiding the transmission of vibration through rigid connections.

Before installation, clean the flange face and lifting lug holes, and check that the muffler is free from deformation and damage, and that the gaskets are free from aging and cracks.

Axially, it is positioned against the exhaust manifold; radially, it is unrestrained to ensure free thermal expansion and contraction. After installation, check for air leakage, abnormal noise, and that the spreader is secure.

As required by the model manual, check the fastener torque and sealing condition every 1500 working hours, and tighten or replace the gaskets as needed.
