⚙️ Key Features

• Genuine Volvo Penta crankcase-ventilation support bracket
• Factory shape and mounting-hole alignment
• Supports the oil trap and associated ventilation plumbing
• Helps prevent hose chafing and connection fatigue
• Direct replacement for a bent, cracked or corroded original bracket
• Engine type: 2.4L inline five-cylinder common-rail marine diesel

🔌 Function

Holds the crankcase-ventilation oil trap and hoses in the correct position so vapour can be separated and routed without vibration damage or hose restriction.

⚠️ Common Signs of Failure

• Oil trap or hose movement while the engine is running
• Rattling from a cracked or loose bracket
• Oil-mist leakage around stressed hose connections
• Chafed or kinked ventilation hoses
• Fatigue cracking or corrosion around mounting holes

🛠️ Service Notes

• Offer the bracket up and start every fastener by hand before tightening any of them, so the component is not pulled into a strained position
• Check the mating faces are clean, flat and free of corrosion scale — a bracket that does not sit flat will work loose and let the component move
• Renew self-locking nuts, lock washers, tab washers or thread-locking compound wherever the original assembly used them, and tighten to the figure given in the workshop manual for your engine
• Where the bracket carries a rubber mount or bush, renew that at the same time rather than reusing a perished one
• On brackets in the inlet and exhaust area, never force alignment to make the holes line up — cure the misalignment at its source, or the bracket and the component it holds will both crack
