This document provides a test plan for a Perkins Vista A 105HP fuel injection pump with specifications and procedures. It lists the pump rotation as clockwise, governor spring position as 5, and plunger diameter as 7.0 mm. The test conditions are specified as ISO 4113 fluid at 40°C, 0.3 bar inlet pressure, and specific nozzle and holder components. The test procedures include measuring delivery, governor response, cut-off, idle delivery, shut-off, timing, and overcheck values to validate the pump settings.

PRE-OVERCHECK NOTES
.
The Overcheck section of this plan has been developed in
conjunction with the Original Equipment Manufacturer.
Providing all values are achieved, the pump settings will
maintain the original homologated engine performance. Failure to
attain any one of the values will indicate a pump setting or
function failure and require further investigation.
.
No adjustments to be made unless otherwise stated.
