Hub Driving Coupling – Pump Side (FIAT 697 pattern)

The Marbed 9026 is a pump-side hub driving coupling for mounting diesel injection pumps on test benches. It provides an accurate, rigid interface to transmit torque and maintain alignment during calibration and performance tests. Application: FIAT 697. 

Key Benefits

• Correct fitment for FIAT 697 hub pattern → quick, repeatable setup. 

• Stable torque transmission and accurate alignment during testing. 

• Adapter base for Marbed puller couplings (e.g., 9429/9430) where required.

Key Features

• Family: Driving couplings for hubs (pump side).  

• Bolt pattern: Ø93; 4 holes Ø10 

• Typical use: mounting/drive of Bosch in-line “P” family and similar pumps as installed on FIAT 697.  

• Works in systems with anti-backlash/test-bench couplings per Marbed catalog.  

Operational Functions

• Interfaces the pump hub to the bench drive; maintains concentricity and rigidity.  

• Used standalone for driving, or as adapter under specific puller couplings (e.g., 9429/9430) for removal/installation tasks.  

Technical Data

• Code: 9026

• Application: Pumps mounted on FIAT 697

• Bolt pattern: Ø93; 4×Ø10 

• Related components: puller couplings 9429, 9430 (require 9026 as adapter when specified)

• Family reference: Driving couplings for hubs in Marbed test-bench catalog. 

Use Cases

• Diesel workshops and test centers running calibration on pumps from FIAT 697 applications. 

• As adapter base when using puller couplings for hub extraction/installation.
