About 5110850960 - Piston Ring
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5110850960 is a piston ring catalogued for MTU 4000 engines. Catalog history lists XT3510100044 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 0.006 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
