Welcome!

The tool is not specific to one single injection-pump model.

Zexel service documentation lists 157926-5821 in several applications, including:

• PE-ZWY type injection pumps — removal of the RSV governor flyweight
• PE(S)-P type injection pumps — removal of pumps fitted with an SA timing device
• PE(S)-A, -AD and -MD type injection pumps — removal of pumps fitted with SA, SCD and SAG timing devices
• SA type timing devices
• SCD type timing devices
• SBZ type timing devices
• SAG type timing devices

The common functional characteristic is the M24 × 1.5 thread.

Depending on the Zexel documentation and application, the same current part number 157926-5821 may also appear associated with older Zexel references, including 157926-6210, 157926-6220 and 157926-5810.

Cross-reference

Identification note

When identifying this tool, the application and M24 × 1.5 interface are more significant than the description used in an individual catalogue.

Zexel documentation describes 157926-5821 variously according to the operation being performed—for example as an extractor for a timing device, for a pump equipped with a timing device, or for an RSV governor flyweight.

These descriptions refer to the service operation in which the tool is used, rather than necessarily identifying different tools.

Before ordering

If the Zexel number is no longer readable or the application is uncertain, identify:

• the injection pump type;
• the timing-device/governor type;
• the thread to be engaged by the extractor.

For Zexel 157926-5821 / M24 × 1.5 applications, the corresponding Marbed reference is 9091.
