875566 Piston Ring Kit | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta piston ring kit from the Engine group, weighing 0.05 kg and listed for 3 applications on MD series engines. Unlike the other MD ring kits in this run it carries no bore grade and no production range, so nothing in its listing separates it from the standard-bore kits 875476 and 875547, which cover the same 3 MD applications and are split between them by production order. If your engine falls in one of those production ranges, order the kit that names it; otherwise order this one by part number against the engine's parts list.
