# 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.

-   0.009 kg
-   9 applications across TMD, MS, TAMD and MD engines
-   Engine group
-   Separate part from plug 859877 — order by number, as no size is published for either

## 🔌 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
