The Injector Calibrator HA290 was designed and built to provide extremely accurate and rapid testing of all Cummins PT injectors without the need for master injectors. It is a service level calibrator and is fully compatible with test standards and procedures set by Cummins.
Speed of Operation
The metering cylinder of the Injector Calibrator HA290 permits injector output to be measured accurately over as few as 50 ‘shots’. The layout of the HA290 is arranged to reduce injector testing time. Features such as simple cam changing, easy access to burnish the injector orifice, automatic injector clamping and sealing together with easily fitted adaptors means that the productivity of the HA290 is unequalled.
Accuracy
The Injector Calibrator HA290 is fitted with a synchronous drive motor capable of maintaining 1050 rpm within plus or minus 1 rpm. Test oil temperature is maintained to within plus or minus 1° Fahrenheit, injector clamping pressure is controlled at 74 or 12 psi., within a tolerance of 1 psi.,
test oil pressure is automatically controlled at 100 psi., with a tolerance of 0.25 psi. Versatility
The HA290 has the capability to accept any type of Cummins PT injector, changes of cams, adaptors and stem extensions to handle different injectors
is a simple and speedy operation. The easily changed cam is mounted vertically, and a transparent cambox lid enables rapid identification of the type
of cam fitted. Two purpose built tool boxes are conveniently positioned and are provided with clips and brackets to stow tools, adaptors and stem
extensions. The left hand box contains the cams, box spanner and ‘T’ bar, the right hand box contains the injector adaptors and stem extensions. |

Servicing
Test oil and filters are easily changed, and an audit kit HB164 is available to enable operators to verify and maintain the accuracy of the Injector
Calibrator HA290.

Camshaft Drive
Motor |
| |
| 1.5 hp synchronous motor, totally enclosed fan cooled, direct on line starting with overload protection. Running speed
1800 rpm at 60 Hz or 1500rpm at 50Hz. |
| The drive is by means of a timing belt and toothed pulleys on the motor and camshaft. |
| The ratio of the pulleys is such that the camshaft has a running speed of 1050rpm. |
