Description
A lock ring is a retaining ring used to connect the regulator assembly to the fuel injection pump of a diesel engine. The regulator is a device that regulates engine speed by controlling the amount of fuel injected into the engine. The lock ring is typically a small metal component designed to fit on the end of the regulator assembly and engage a groove or notch on the fuel injection pump.
Features
- Ensures sufficient tightness and resistance to external forces to prevent movement or tampering.
- Maintains sufficient strength and wear resistance.
Applications
The lock ring is used in the regulator to help prevent the regulator assembly from moving or rotating, ensuring proper adjustment of motor speed. It is most commonly used in Cat 24H motor graders, 320, 3408, 3408, 3408B, 3408, 3408B, 3408B, 3408C, 3408C, 3412, 3412C, 3412C, 3412D and 3512 motors (piston), 3408, 3408B, 3408C, 3408B, 3408C, 3408C, 3412, 3412, 3412C, 3412C and PM3412 generator sets, 589 and 591 pipelayers, 631C, 631D, 631E, 631F, 633D, 633E, 637D, 637E, 637F, 639D, 639E, 651E and 657E rubber-tire scrapers, 631E, 6377E rubber-tire scrapers E, 657E and 657F scrapers, 768C, 769, 769B, 769C, 771C, 772B, 773B and 775B trucks, 772 trucks, 834B wheel dozers, 836 compactors, 910, 988B, 988F, 990, 992C, 992D, 992G and R1700G wheel loaders, D10N, D10R, D8L, D9, D9L, D9N, D9R and D9T track-type dozers, D44, D44B, D550 and D550B dump trucks, and PM-565, PR-1000, PR-1000C, PR-450C, PR-750B and PR-750C paving equipment.
