Test Facilities


At GCL Diesel we take pride in our state of the art test facility. In our test room, all repaired units are tested and calibrated on factory designed and built test benches to ensure they meet manufacturer specifications. With an ever-increasing number of auxiliary devices and electronic components found on today’s generation of injection pumps, precise analysis and calibrating is essential. GCL is constantly investing in new equipment and technology to ensure that we are current with the latest testing and diagnostic devices.

If you own a Diesel Powered vehicle, you deserve to have it maintained by a Diesel Technician. At GCL, we specialize in the repair of all Diesel Fuel Systems including:

  • Common Rail Fuel Systems
  • Mechanical Fuel Pumps
  • Electronically Controlled Fuel Pumps
  • Electronic Unit Injectors (EUI / HEUI)

Injector Testing


We offer complete service to all makes of diesel fuel injectors using the latest in cleaning and test equipment .

We can take your injectors and tell you quickly if the spray pattern, nozzle chatter, and opening pressure meet specifications. Our various state of the art injector testers will help determine the status of your injectors.

If Injectors Pass...

 

Tested and Cleaned

If the injectors pass testing they are cleaned and fitted with new gaskets, sealing washers, and dust seals as necessary.

If Injectors Fail...

 

Complete Overhaul

Only genuine nozzles are used in our repairs to ensure the quality and exact standards of new OEM specifications are met.

Mechanical Injectors

  • Mechanical Injector Service Report
  • Diesel and Gasoline Mechanical Injector testing
  • Pop tested — the process of testing fuel injectors to see at what pressure they spray fuel. The injectors should pop at the manufacturers recommended pressure so it creates a proper atomized spray pattern.
  • We use fresh, pristine fuel and oil for testing. This test removes the possibility of injector failure due to upstream electrical failure
    (for example: bad FICM, poor oil, lift pump pressure, high pressure oil pump efficiency).

Common Rail Injectors (Bosch EPS 205 Test Bench)

  • Common Rail Test Results

    Common Rail Test Results

Using our new state-of-the-art EPS 205 Bosch High Pressure Common Rail Test Stand, we are able to quickly and accurate test most common rail injectors.

  • Testing of common rail injectors includes verifying electrical solenoids are working correctly.
  • Our 205 bench will test fuelling at pre-injection, idle, partial load, full load, leak test and 2 emissions points.
  • We use fresh, pristine fuel and oil for testing. This test removes the possibility of injector failure due to upstream electrical failure (for example: bad FICM, poor oil, lift pump pressure, high pressure oil pump efficiency).
  • We carry reseal kits and or o-rings and tip gaskets to reseal injectors after testing
  • Common rail injectors are not repairable.
  • We carry a range of new and replacement remanufactured injectors.

Common Rail Injectors (IFT Bench)

    Common Rail Injectors (IFT Bench)

  • Testing of common rail injectors includes verifying electrical solenoids are working correctly.
  • IFT Bench will test electrical, leakage, nozzle opening pressure, spray pattern, return and delivery.
  • We use fresh, pristine fuel and oil for testing. This test removes the possibility of injector failure due to upstream electrical failure
    (for example: bad FICM, poor oil, lift pump pressure, high pressure oil pump efficiency).
  • We carry reseal kits and or o-rings and tip gaskets to reseal injectors after testing

  • Testing of HEUI injectors includes fuel delivery at start fuel, idle, partial load and full load.
  • We use fresh, pristine fuel and oil for testing. This test removes the possibility of injector failure due to upstream electrical failure
    (for example: bad FICM, poor oil, lift pump pressure, high pressure oil pump efficiency).
  • We carry complete injector reseal kits
  • HEUI injectors are not repairable.
  • We carry a range of replacement remanufactured injectors.

Injection Pump Testing and Rebuilding


We offer complete service to all makes and types of diesel fuel pumps using the latest in cleaning and test equipment. From new common rail technology to field-tested mechanical pumps, we are the fuel pump experts.

We can take your pumps and by using our calibrated equipment tell you if they meet OEM specifications. Our various state of the art injection pump test benches will help determine the status of your diesel fuel pump and whether it is good to go or needs a complete overhaul.

If Pumps Pass...

 

Tested and Cleaned

Pumps are flushed prior to testing and fitted with new gaskets where required.

If Pumps Fail...

 

Complete Overhaul / Replacement

Only genuine replacement parts are used in our repairs to ensure the quality and exact standards of new OEM specifications are met, and pumps re-tested / calibrated.

Overhaul and Rebuild

If it’s determined that your pump needs an overhaul and rebuild, our professional service technicians can do that using genuine original equipment parts and assemblies. Steps include:

  • Complete disassembly of the unit and subassemblies

  • Cleaning and detailed inspections

  • Missing, worn, or broken parts replaced

  • Complete re-assembly and calibration

  • Completed to OEM Specification on calibrated test benches
