The 612630020028 coil spring loaded oil-control ring serves as the vital oil regulation component engineered to control cylinder wall oil film thickness and prevent excessive oil consumption in Shacman heavy-duty diesel engines.
This 612630020028 oil-control ring consists of two thin steel rails separated by a stainless steel coil spring expander, which provides consistent radial pressure against the cylinder wall throughout the ring service life.
The precision-formed twin rail design of the 612630020028 features sharp scraping edges that remove excess oil from the cylinder wall on the downward stroke while allowing sufficient oil to remain for compression ring lubrication.
This 612630020028 component incorporates an integrated coil spring expander that maintains consistent tangential tension even as the rails wear, ensuring reliable oil control performance throughout the complete engine service interval.
The high-strength steel rail construction with specialized surface coating provides excellent wear resistance and conformability to cylinder wall irregularities, maintaining effective oil film regulation under all operating conditions.
The 612630020028 oil-control ring is engineered to meet the specific rail width, spring tension, and coating requirements of Shacman engine piston assemblies, assuring seamless compatibility with the piston ring groove.
By providing dependable oil film regulation, this oil-control ring contributes directly to proper engine lubrication, reduced oil consumption, and maintained emissions compliance in demanding operational environments.
The 612630020028 oil-control ring is manufactured from premium high-strength steel rails with precision forming and a stainless steel coil spring expander, delivering consistent radial tension and exceptional conformability for reliable oil regulation.
The precisely controlled rail profile and spring tension of the 612630020028 ensure optimal oil scraping effectiveness while minimizing friction against the cylinder wall, contributing to improved fuel efficiency and reduced engine wear.
The carefully engineered coil spring design of the 612630020028 provides uniform radial pressure distribution around the entire ring circumference, ensuring consistent oil film thickness regardless of cylinder bore distortion or piston movement.
Each oil-control ring undergoes rigorous quality verification, including dimensional inspection, spring tension measurement, and surface coating evaluation to guarantee its performance in demanding oil regulation applications.
The material selection for the 612630020028 prioritizes both wear resistance for extended rail life and spring durability for consistent radial tension throughout the complete engine service interval.
The 612630020028 oil-control ring’s design has been validated through extensive engine dynamometer and oil consumption testing to ensure reliable performance throughout the complete engine service interval.
Replacement of the 612630020028 oil-control ring requires removing the piston assembly, carefully extracting the old ring components from the lower groove, and installing the new spring expander and rails with proper orientation.
After installation of the 612630020028 oil-control ring, verify that the coil spring expander ends are properly butted together without overlap, and that both rails rotate freely within the groove after assembly.
Periodic inspection of the 612630020028 oil-control ring through oil consumption monitoring and borescope examination during major maintenance intervals is recommended within engine service schedules.
When installing the 612630020028 oil-control ring, install the coil spring expander first into the groove, then carefully spiral each rail into position above and below the expander without twisting or permanently deforming the rails.
It is critical to ensure the spring expander ends are not overlapped when installing the 612630020028, as overlap creates a high spot that will cause localized high pressure and accelerated cylinder wall and ring wear.
During engine overhaul, pay close attention to the oil-control ring of the 612630020028 for signs of rail wear, spring tension loss, or carbon clogging of oil return holes indicating the need for ring replacement and groove cleaning.
