859876 Plug | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta plug from the Engine group, weighing 0.009 kg and listed for 9 applications across the TMD, MS, TAMD and MD engine series. Plug 859877 sits beside it in the same group with the same nine applications; the two differ in weight but the published detail gives no dimension or thread, so the two must be ordered by number and not by size.

🔌 Function

Blanks off a drilling or gallery in the engine casting so oil or coolant follows its intended route.

⚠️ Common Signs of Failure

• Weeping or seeping from the plug rather than from a joint face
• Drive recess rounded or corroded so the plug cannot be gripped
• Sealing washer or taper found crushed hard on removal
• Plug found loose, having backed out under vibration

🛠️ Service Notes

• Renew any sealing washer with the plug
• Do not overtighten into an alloy casting; the thread will strip long before the plug gives way

📦 Condition

• Brand new
• Supplied in original or equivalent packaging
