Hartzell Engine Tech V-Band Clamp 490127-0001

FAA-PMA Turbo Exhaust Clamp for Continental TSIO / TIO Series Engines

The AeroForce 490127-0001 V-Band Clamp is an FAA-PMA approved replacement for Continental turbocharged engines including TSIO-360, TSIO-520, TSIO-550, and related models.
This clamp secures the exhaust-to-turbocharger flange connection, helping maintain proper exhaust sealing in high-temperature turbo applications. A compromised V-band clamp can lead to exhaust leakage, turbocharger performance loss, carbon monoxide risk, and potential engine power loss.
AD 2023-09-09 placed a 500-hour life limit or recurring inspection requirement on many spot-welded V-band clamps. The Hartzell PMA clamp is not subject to this AD, offering Continental operators a durable alternative without recurring life-limit replacement.

Why Choose 490127-0001:

• FAA-PMA approved for applicable Continental TSIO / TIO engines
• Not subject to AD 2023-09-09
• Weld-free, rivet free construction to eliminate legacy weak points
• Braided wire cable and a floating retainer for improved load distribution and durability
• Cable safety retention band for additional clamp security
• Designed for high-heat turbocharger exhaust connections
• Direct replacement for applicable OEM Continental part numbers

Inspection and Replacement Considerations

• Replace the clamp if any of the following are observed:
• T-bolt cracking or deformation
• Clamp band distortion or uneven seating
• Exhaust leakage at turbo flange
• Inability to maintain specified torque

Inspect during each 100-hour or annual inspection in accordance with Hartzell Engine Technologies Service Information AF3003.
