Each connecting rod uses two bolts. On the common six-cylinder applications, twelve bolts are required for a complete engine. Connecting-rod bolts are highly stressed engine fasteners and should be replaced as a matched set whenever the workshop procedure requires new hardware.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  MD, TMD, AD, TAMD, AQAD, D, TD, DP, DPX, SP, AQD, KAMD, KAD\n \u003c\/li\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Year Range:\n  \u003c\/strong\u003e\n  Approximately late 1970s-2000s, engine model and connecting-rod revision controlled\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\n Full model list at the end of this description.\n\u003c\/p\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  OEM Volvo Penta part number 1542077\n \u003c\/li\u003e\n \u003cli\u003e\n  System group: Engine\n \u003c\/li\u003e\n \u003cli\u003e\n  Connecting rod (big-end) cap bolt\n \u003c\/li\u003e\n \u003cli\u003e\n  Replaces superseded part number 861499\n \u003c\/li\u003e\n \u003cli\u003e\n  Net weight approximately 0.068 kg\n \u003c\/li\u003e\n \u003cli\u003e\n  Fits MD, TMD, TAMD, AD, AQAD, KAD and KAMD 30\/31\/40\/41\/42\/43\/44 series marine diesel engines, plus SP and DP drive applications\n \u003c\/li\u003e\n \u003cli\u003e\n  Supplied as a single bolt\n \u003c\/li\u003e\n \u003cli\u003e\n  Engine type: Volvo Penta four- and six-cylinder marine diesel\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n The connecting rod bolt clamps the connecting rod cap to the rod, holding the big-end bearing shells securely around the crankshaft journal.
