## ⚙️ Key Features

-   Std D size
-   0.313 kg
-   34 applications across the D, TMD, MS, TAMD and MD series
-   Matches big-end bearing kit 859807 and piston ring kit 859642

## 🔌 Function

Provides the replaceable bearing shells the crankshaft main journals run in, carrying the crank in the block on a pressure-fed oil film.

## ⚠️ Common Signs of Failure

-   Deep rumble from low in the engine, worst under load and pulling away
-   Oil pressure falling, especially hot at idle
-   Warning light flickering at low revolutions
-   Bearing metal or bright flakes found in the sump or the filter
-   Shells found scored, wiped or with the overlay worn through to the backing

## 🛠️ Service Notes

-   Ordered by size grade, not by mass — confirm the grade from the crankshaft or the last rebuild record before committing to the Std D set
-   Have the journals measured before fitting: new shells on a worn or out-of-round crank will not last
-   Big-end bearing kit 859807 is normally renewed at the same time
