0020371319 Specification
About 0020371319 - Rectangular Ring
Pistons, liners, and rings are size-graded components. Incorrect grade selection causes premature wear or seizure. We verify size code, engine series, and serial number before quotation. OEM and OEM-alternative grades available.
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
