This part of SAE J968 specifies two types of calibrating nozzle and holder assemblies intended for the testing and setting of diesel injection pumps on test benches.

It applies to:

The approximate range of the calibrating nozzle and holder assembly is up to:

Setting and maintenance requirements are specified in ISO 4008/3.

This SAE Information Report is primarily to familiarize the designer of hydraulic powered machinery with the necessity for oil filtration in the hydraulic power circuit, the degree of system cleanliness required, types of filtration and filters available, and their location and maintenance in the hydraulic circuit.

This SAE Information Report establishes a point system that encourages ease of maintenance actions on off-road machines. The point system minimizes subjectivity in evaluating maintainability as defined in ISO 8927.

This SAE Recommended Practice is intended as a guide toward standard practice but may be subject to frequent change to keep pace with experience and technical advances.

This test code describes tests for determining characteristics of hydraulic positive displacement pumps used on off-road self-propelled work machines as referenced in SAE J1116.

This SAE Standard applies to hydraulic pumps and motors used on off-road self-propelled work machines as described in SAE J1116.

This SAE Recommended Practice was developed to provide a method of recommending the availability of various dimensional output shaft and crankcase flange combinations.

Communicate the process of accurately measuring sound power levels of positive displacement hydraulic pumps commonly used in ground vehicle steering systems. This recommended practice defines the pump mounting (pulley, belt tension, isolation), operating conditions (fluid, speed, temperature, pressure), room acoustics, instrumentation, noise measurement technique and data acquisition setup to be used. Included are recommendations for test sample size, and format for data presentation/reporting.
