Fitment:
Works on all Cummins ISX and Cummins Signature Engine. Use this tool before replacing injectors or metering actuators to save your money.
 
 
Features:
1) Directly replace Cummins 3164001. Includes 3164002-Test adapter plate / NPN O-ring / 3164009-Hose Fitting / 3163527-Flexible Tubing.
 
2) Advanced hard anodized aluminum alloy adapter plate, durability, good rigidity and never rust. Premium grade PVC flexible tube, anti-oxidation and anti-corrosion. Provides a much longer service life.

3)
This kit is used in conjunction a manometer (ST1111-3) to test injectors for leaks that cause an engine to exhibit slow shutdown or excessive run-on after a key-off condition. Checking for combustion gas leaks back through the injector rail check valve or other conditions that will allow gas leakage through the injector into the fuel rail.
 

Excerpt from Quick Service

  1. When the engine is barred over, backpressure is created against the injector by the piston coming up on the compression stroke.
  2. During the test, if the rail check valve is leaking, air is pushed through the rail check valve and into the fuel rail. Pressure is sensed at the test fixture, which is in place of the metering actuator.
  3. If a manometer is connected to the test fixture, pressure will be measured as air escapes through the leaking rail check valve.
  4. If a container of water is used instead of a manometer, bubbles will be seen as air escapes through the leaking rail check valve.
  5. The overhead set marks on the damper are used to identify which cylinder is on the compression stroke, and therefore which injector has malfunctioned, if a change in manometer pressure or bubbles are seen.
