Volvo Penta 1542078 is a genuine OEM connecting rod bolt nut used on Volvo Penta diesel engine applications. Volvo Penta’s official parts shop lists 1542078 as an active genuine part with the description “nut/conn rod bolt”, and current dealer references confirm the same application wording. Current reviewed public sources do not publish a confirmed thread size, hex size, or other dimensional specification for this exact OEM number.
Key Features
- Genuine Volvo Penta OEM part number 1542078.
- Identified in current reviewed sources as a connecting rod bolt nut.
- Individual service fastener sold separately rather than as part of a kit.
- Current reviewed dealer references show approximate product weight around 0.013 kg.
Engine Compatibility
Current public references associate Volvo Penta 1542078 with older Volvo Penta diesel families including MD30, MD31, AD41, KAD42, KAD44, and KAD300. Because this is internal engine hardware, fitment should still be confirmed by exact engine model, serial number, and connecting-rod parts diagram before ordering.
Serial Number Fitment Notice
Connecting rod hardware can vary by engine family, production range, and rod/bolt design. Confirm Volvo Penta 1542078 by engine serial number and by matching the original nut to the correct connecting rod bolt location before ordering. Volvo Penta’s parts guidance also directs owners to identify the correct engine, shield, or drive when locating genuine parts.
When This Part Needs Replacement
This nut is typically replaced during connecting rod service, engine rebuild work, or any repair where the original rod fastener hardware is damaged, worn, or specified for replacement during reassembly. Because current reviewed sources identify 1542078 specifically as connecting rod bolt hardware, it should be treated as critical engine fastener hardware rather than a general-purpose nut.
Installation Notes
Install only after confirming the exact engine application and matching the nut to the original connecting rod bolt setup. Since current public references confirm the part number and function more clearly than they publish torque or dimension data, serial-number verification and use of the correct Volvo Penta service information for the engine being rebuilt are the safest checkpoints before final assembly.
Alternate/Superseded Part Numbers
Current reviewed public sources clearly identify 1542078 as the active Volvo Penta number for this connecting rod bolt nut. No confirmed newer Volvo Penta supersession is shown in the reviewed references.
Parts Desk Insight
For internal engine fasteners like 1542078, the strongest buying checkpoint is the exact engine serial number and rod hardware diagram position, not the word “nut” alone. Current references point clearly to connecting rod bolt use on older Volvo Penta diesel families, so serial-number confirmation is the cleanest way to avoid ordering the wrong internal fastener.
