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
