Toledo HEUI Master
As a result of the ground up research & development process at Hartridge the Toledo HEUI Master combines the instantly recognisable and trusted ‘Sabre’ platform with brand new features developed specially for HEUI technology. The All-Makes test plan database covers the majority of the HEUI parc so workshops can maximise the revenue opportunity that testing HEUI represents.
Hydraulic Electronic Unit Injector Testing Made Easy
Thanks to the same exacting engineering principals stemming from our OE heritage we have developed a new platform which has unparalleled benefits for the workshop and covers most of the HEUI injector parc. The Toledo focuses on ease of use at every stage so that a technician who is new to HEUI technology can effectively test injectors, as well as having more advanced settings available ready to progress as the workshop evolves.
The Toledo HEUI Master incorporates multiple patents pending including innovations developed specifically for this machine, as well as patented technology from the Sabre CRi Master. The lower mount of the fixture tilts forward. This patent pending design makes it possible to fit the larger injectors in situ with ease. We also have developed a patent pending nozzle sealing tool which works with the injector applications to lift and place the nozzle sealing cap.
Another patent pending feature is found in each application kit. Each injector is secured into place to fully seal the nozzle for testing thanks to two quick clamping levering arms. They help to ensure the injector is engaged quickly and released rapidly with the minimum effort. The injector application kits devised for the Toledo HEUI Master use Hartridge's simplified click-in-place cabling and are tailored for both side feed and top feed injectors.
Testing HEUI injectors has historically been messy. Once they are out of place from the engine it results in lots of fluid being sprayed out during testing and can be problematic to control. Thanks to the splash guards in the application kits, the testing fluid is directed down to the bottom of the testing chamber which flows directly back into the tank. These special adaptions make HEUI testing clean, easy and safe for the workshop and no wasted fluid means that just a 10L tank is sufficient.
We have applied our decades of experience with OE test plan creation processes to develop test plans with validated limits for all test conditions and machine to machine repetition. When testing an injector, the technician has the ability to auto-run a full test, manually select single steps, skip test steps, or ask that the test stops should a test step fail, providing ultimate control. Hartridge test plans provide comprehensive part number level coverage for a vast number of HEUI injectors.
As part of our mission to make HEUI testing easy, we have purposefully sought to develop the most possible cross over of injectors in our application kits. As a result, only 7 application kits are required to test the majority of all HEUI injectors including:
Accessories also work across multiple kits to avoid unnecessary duplication. A benefit of having the hydraulic fuel and intensifier lines permanently connected to the unique fixture, as standard, is that there are less components and cost for the workshop to invest in, as well as speed when installing the injector for testing.

Intuitive Touch Screen
The Toledo is operated from a web enabled, app-style touch screen tablet with magmah Touch software. The interface designed by Hartridge with unique programming and icons makes HEUI testing easy. Picture guides clearly show what tooling is required, and the rapid streamlined test plan selection method still allows the technician to customize a test if required. The software provides a dynamic real-time view of the test progress, and can save test results for later use.
Hartridge's unique, patented Closed-Loop technology constantly monitors the power used by the internal pump 10 times per second to make sure the Toledo's operation remains stable and that full power of the pump is available to maximize flow output at high pressures.
Not only does it ensure that the power draw is constantly balanced, but it means the Toledo HEUI Master can be powered by domestic power supplies making installation and use in the workshop straightforward and instant.
Unlike other methods of measuring injector response time which only monitor electrical signals to determine solenoid actuation, Hartridge measures the Full Event Response Time (FERT).
FERT testing gives you a complete view of the response time of the injector from electrical activation to the injection event.
Using Hartridge test plans FERT has the advantage of helping to identify a fault that would otherwise be left undiagnosed, despite fuel delivery tests being within limits.
Two domestic electrical mains connections are required:- Low voltage: 1 of 100-120 Vac (10amps) and 1 of 200-240 Vac (16amps) - High voltage: 1 of 200-240 Vac (10amps) and 1 of 200-240 Vac (16amps) The machine weighs 160kg fully loaded with calibration fluid, and 150kg dry. You must use Hartridge specified fluid Rock Valley C3112 Type 2 which is available from Hartridge with part number 8802010. Dimensions are 610mm (W), 610mm (D), and 1100mm (H).
