3863066 Adjusting Washer | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta adjusting washer 3.05 mm thick, weighing 0.007 kg and listed for 16 applications across the DPH and D families. It is the thickest of the graded set yet carries the lowest published weight of the four, which cannot be right for a plain washer — treat the weight as unreliable and order on the 3.05 mm figure, with 3863063, 3863064 and 3863065 covering 2.85, 2.90 and 3.00 mm.

🔌 Function

Sets the shim thickness in a stack so the clearance or preload of the assembly falls where it should.

⚠️ Common Signs of Failure

• Clearance or preload out of specification after assembly
• Washer dished or indented on one face
• Polished marks showing it has been turning
• Play or backlash returning after a rebuild

🛠️ Service Notes

• Order on thickness only — the published weight for this grade is inconsistent with the rest of the set
• Measure the existing shim and the clearance it gave before choosing the replacement grade

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
