The spring plate designated by code K 72140 works in conjunction with the flexible rod K 72135, providing essential tension and support within the ZV40/48 engine assembly. It helps absorb vibration and maintain precise rod alignment during engine operation. This component ensures the flexible rod can transmit force or motion reliably, especially in systems where accurate movement is critical, such as fuel injection or lubrication control. Manufactured from resilient, wear-resistant material, the spring plate enhances both operational stability and service life of connected parts.
