Proper clamping force is essential to preventing exhaust leaks, which can create operator safety hazards and reduce engine performance.

Replace the 8T6675 if you see:

• Visible cracking or fracturing of the clamp band
• Rusting or corrosion through the clamp body
• Leaking exhaust gases at the connection despite proper torquing
• Stripped bolt threads that prevent achieving the specified clamp torque

Clamp compatibility depends on the pipe OD, pipe wall thickness, and the pipe end profile. For related engine and exhaust components, visit our engine parts category. Verify the part number against your service documentation.

Position the clamp squarely over the pipe joint. Snug both fasteners evenly before final torquing. After initial startup and heat cycling, re-check and re-torque the clamp ??? new exhaust clamps typically seat slightly during the first thermal expansion cycle.
