Installation Notes
Professional mechanic or diesel specialist installation recommended:
- Ensure exhaust system is cool - Never work on exhaust components when the engine has been running
- Locate the exhaust brake unit - Typically installed in the exhaust pipe between the turbocharger outlet and the muffler
- Remove the old unit - Unbolt the exhaust brake unit from the exhaust pipe flanges; remove any mounting brackets
- Inspect exhaust pipes - Check the connecting exhaust pipes for damage, corrosion, or misalignment
- Clean flange surfaces - Remove all old gasket material and debris from the flange mating surfaces
- Install new gaskets - Position new exhaust gaskets on both flange connections (if applicable)
- Mount the new unit - Position the new exhaust brake unit between the exhaust pipe sections; align the flanges
- Install mounting bolts - Hand-start all flange bolts; do not fully tighten yet
- Secure mounting brackets - Attach any support brackets or braces to ensure proper alignment
- Torque flange bolts - Tighten all flange bolts evenly to manufacturer torque specifications
- Connect actuator lines - Reconnect the pneumatic/vacuum actuation line to the actuator; ensure a secure connection
- Check electrical connections - If the unit has electrical components, ensure proper connection
- Inspect clearance - Verify no components contact wiring, fuel lines, or other sensitive parts
- Test operation - Start the engine; engage the exhaust brake; verify proper valve movement and braking effect
- Check for leaks - Inspect all exhaust connections for leaks while the engine is running
- Road test - Test the exhaust brake operation on a safe downhill grade or under load
Quality Control
- Material Verification: Confirms housing and valve materials meet high-temperature and corrosion resistance specifications
- Valve Operation Testing: Each unit tested for smooth valve actuation and proper sealing
- Actuator Performance Test: Actuator movement and response verified to ensure consistent operation
- Dimensional Inspection: Flange spacing, mounting points, and overall dimensions verified for exact fit
- Pressure/Leak Testing: Unit tested for exhaust gas sealing integrity
