Siemens VDO Common Rail Adjustment Shim

Siemens VDO CR Adjustment Shim - 077-108

The Siemens VDO common rail (CR) adjustment shim is one of the most commonly used critical adjustment components in Siemens brand diesel injectors, operating precisely under high pressure and contributing to the stability of injection pressure. By ensuring precise control of the amount of fuel injected, it helps optimize engine performance and emission values. It is a standard component in almost all Siemens diesel injectors. To achieve high surface quality, superior wear resistance, and high measurement precision, it is manufactured with high accuracy using a lapping process.
