21636474 Connection Block | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta connection block weighing 0.054 kg and listed for thirty-one D3 applications, chiefly the F, G and H generations. Volvo Penta's reman catalogue calls for it as an order-also item alongside the D3 remanufactured long block 3801634, together with hollow screw 21636477 and 21750952, so it is one of the small parts that has to go on the same order if the engine change is not to stall for want of a fitting. It is a new genuine part rather than a remanufactured one, so there is no core to return against it.

🚤 Compatibility

• Engine Family: D
• HP Range: 110-220 HP
• Year Range: Approximately 2013 - 2018

⚙️ Key Features

• For thirty-one D3 applications, chiefly the F, G and H generations
• 0.054 kg
• Called for alongside the D3 reman long block, with hollow screw 21636477
• New genuine part - no core to return

🔌 Function

Forms the fixed junction where a line is landed on the engine, clamped by a hollow screw that carries the flow through its centre.

⚠️ Common Signs of Failure

• Weeping at the joint once the engine is warm and up to pressure
• Sealing faces scored or the washers flattened when the joint is opened
• Threads pulled or the seating distorted by over-tightening

🛠️ Service Notes

• Order hollow screw 21636477 at the same time - the reman catalogue lists the two together against the D3 long block
• Use new sealing washers rather than the old ones, and tighten to the engine's own figure
