🔧 Product Description

A heavy-duty support bracket used in the charge-air cooler and intake-pipe arrangement on selected Volvo Penta TAD16 and TWD16 engines.

🚤 Compatibility

Typically suits:

• Volvo Penta TWD1643GE

• Engine Family: TWD

⚙️ Key Features

• Supersedes earlier bracket 3840411
• Supports heavy cooler and intake-pipe components
• Reduces vibration loading on charge-air hoses
• Engine type: TAD16 or TWD16 inline-six turbocharged diesel

🔌 Function

Supports and aligns the charge-air cooler and connecting pipes.

⚠️ Common Signs of Failure

• Cooler movement
• Charge-air hose failure
• Boost leakage from misaligned connections
• Excessive vibration or pipe fatigue

🛠️ 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
