21647985 Bracket | Genuine Volvo Penta Part

🔧 Product Description

Auxiliary mounting bracket used on a serial-specific Volvo Penta diesel engine. The current part replaces earlier bracket 20405805 and supports the associated pipe, shield, electrical or engine-mounted component.

• Genuine Volvo Penta structural bracket
• Factory hole spacing and offset
• Heavy-duty corrosion-protected construction
• Serial-specific installation position

🔌 Function

Supports and locates an auxiliary engine component while controlling vibration and maintaining clearance.

⚠️ Common Signs of Failure

• Cracking or bending
• Elongated bolt holes
• Component chafing or movement
• Fastener loosening
• Corrosion at mounting points

🛠️ 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
