## 🔧 Product Description

## 🚤 Compatibility

Typically suits:

-   Volvo Penta D9A2L MH
-   Volvo Penta D9A2M MP

-   **Engine Family:** D

## ⚙️ Key Features

-   Genuine forged connecting rod
-   Matched big-end and small-end geometry
-   Correct mass and structural specification
-   Designed for the listed engine family
-   Bearing shells, bushing, bolts and piston pin are separate unless listed
-   Engine type: Volvo Penta 9-litre inline six-cylinder marine diesel
-   6 used per assembly

## 🔌 Function

Transfers combustion force from the piston to the crankshaft and converts reciprocating piston motion into crankshaft rotation.

## ⚠️ Common Signs of Failure

-   Knocking from the big-end or small-end
-   Bent or twisted rod causing piston or liner wear
-   Fretting at the cap joint
-   Cracks, heat discolouration or damaged bolt seats
-   Repeated bearing failure or abnormal piston protrusion

## 🛠️ Service Notes

-   Return each rod to its own bore and its original orientation, with its own cap the right way round — caps are machined with their rod and are not interchangeable
-   Fit new connecting rod bolts unless the manual for your engine expressly permits reuse, and follow its torque-plus-angle sequence exactly; these fasteners are stretched into place, and a reused or mis-tightened bolt is a thrown rod
-   Measure the journals, the bearing shells and the rod's big-end and small-end bores against the figures in the manual for your engine, and check the rod for bend and twist before it is used
-   Fit the shells clean and dry into their seats with the locating tabs home, then oil only the running faces — never scrape, shim or adjust a bearing shell
-   Lubricate the bolt threads and faces only as the procedure specifies, and check the rod turns freely with the correct side clearance before moving on
