⚙️ Key Features

• Genuine Volvo Penta steering-system bracket
• Maintains pump and pulley alignment
• Supports the original steering reservoir and hose arrangement
• Used with support rubber 21434108
• Designed for marine V8 accessory-drive loads
• Engine type: V8 marine petrol

🔌 Function

Supports the steering pump and maintains correct alignment between the pump pulley and accessory-drive belt.

⚠️ Common Signs of Failure

• Belt misalignment or squeal
• Steering-pump movement
• Repeated hose or fitting leakage
• Excessive accessory-drive vibration

🛠️ 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
