About 5800300617 - Composite Piston
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5800300617 is a composite piston catalogued for MTU 956 engines. Catalog history lists X58003700003/80 as its later number; we check whether the later part can be fitted alone or needs related parts changed with it. The catalog unit weight is 26.966 kg, which we use to estimate freight before quoting.
Technical Notes: Pistons and liners
Pistons, rings, and wet cylinder liners form the combustion chamber and carry the highest thermal loads in the engine. They are usually replaced during a major overhaul, and liner protrusion and size grades have to be checked so the cylinder head seals correctly.
When This Type of Part Is Usually Replaced
- oil consumption or blow-by rises beyond the expected level
- borescope inspection shows liner scoring, bore polishing, or ring damage
- liner cavitation is found on the coolant side
Checks Before Ordering
- Order liners with their sealing rings, and pistons with complete ring sets
- Size grades and weight classes must be matched within one engine
- Measurements from the inspection record decide which grade to order
