21545619 V-Clamp | Genuine Volvo Penta Part

🔧 Product Description

A stainless-steel V-band clamp used to secure the designated exhaust-pipe, turbocharger or aftertreatment flange on Volvo Penta D11 and D13 heavy-duty diesel installations.

⚙️ Key Features

• Approximate clamp diameter: 4-5/16 inches
• High-temperature stainless-steel construction
• Provides even circumferential flange loading
• Designed for exhaust-pipe and aftertreatment joints
• Suitable for heavy-duty marine and industrial engine service

🔌 Function

The clamp draws two mating exhaust flanges together and maintains a gas-tight joint under heat, vibration and thermal cycling.

⚠️ Common Signs of Failure

• Soot leakage around the joint
• Cracked or distorted clamp band
• Seized or stretched clamp bolt
• Joint movement or heat damage nearby

🛠️ Service Notes

• Bring the two flanges squarely together before the clamp goes on — a V-clamp centres and holds a joint but cannot pull a misaligned pipe into line
• Seat the clamp evenly round the flanges and nip it up lightly, then tap around the circumference with a soft mallet so the band settles and the flanges centre before final tightening
• Tighten in stages to the figure in the workshop manual for your engine and no further; the clamp is meant to pinch the flanges while still allowing for expansion and vibration, and overtightening distorts the band or the flanges
• Renew the clamp if the band is stretched, cracked or corroded, or if the bolt, nut or trunnion is damaged — a fatigued clamp can let the joint go completely
• Recheck the clamp after the first run up to working temperature, and again at the next service
