Injector Installation And Removing in Cat Diesel Engine 3116

The fuel injector is a device used to inject fuel, which can judge the fuel injection situation according to the signal from the ECU. The fuel injector has spray characteristics such as atomization particle size, oil mist distribution, oil beam direction, range, and diffusion cone angle, and belongs to a finishing instrument. The spray characteristics include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle, etc. These characteristics should meet the requirements of the diesel engine combustion system, so that the formation and combustion of the mixture can be perfected, and higher power and thermal efficiency can be obtained. The fuel injector is composed of an orifice nozzle, hydraulic servo system (control piston, control metering hole, etc.), solenoid valve, etc.

 

Cat 3116 injector installation

Before Cat 3116 injector installation, the first thing you need to do is to check the brass sleeve in the cylinder head, whose job is to provide a seating surface for the injector, so any visible wear will require you to machine or make a cat 3116 injector sleeve replacement. It is essential to understand Cat 3116 injector installation

1. Clean the cat 3116 injector sleeve hole. It is no longer necessary to install an O-ring on the injector because the installation tool creates a seal between the injector body and the seat. Then apply a thin layer of oil after installing the injector body O-ring.

2. Place the injector in the hole of the nozzle and push the return spring firmly down until you hear a distinct clicking sound. Then, turn the injector until it engages the fuel control rack. Next, torque secure bolts to 9 ft-lb + or - 2 ft-lb.

3. Install the injector into its hole using the injector mounting tool. The stationary tool must be supplied by Caterpillar or compression may leak through the injector into the fuel system.

4. Re-tighten the injector compression bolt after completing the Cat 3116 injector installation procedure.

 

Cat 3116 injector removing

The Cat 3116 injector is easy to remove and makes a Cat 3116 fuel injector replacement with a little work and the right Cat 3116 injector tools. The good news is that there is no need for fuel injection lines thanks to a common fuel passage in the head, fed by a transfer pump located in the governor housing. Here's how to do Cat 3116 injector removing

1. Remove the valve cover and the 4 screws retaining the rocker arm shaft group, whichever gas canister you get.

2. Use a Cat #1U-8013 5mm hex driver to remove the rocker arm shaft and injector adjustment screws.

3. Use the appropriate tool Cat # 5P-0302 to carefully lever the underside of the injector steel body {other side of the injector bracket}.

4. Swing the 3116 Cat injector towards the front of the engine to disengage the rack assembly.

5. Pull and swing the syringe away from the head. It is important to note that the injector should not be moved to slide the fuel rack until the spring has been slightly compressed. If you push back and forth, you will damage the frame. If the rack can be easily slid back and forth without compressing the spring, then it is time to replace it. This extra wear can cause the injector to stick.

 

It is important to understand how to install and remove the Cat 3116 injector. From cleaning the injector sleeve hole to using the right tools, attention to detail is key. Following these steps will help avoid potential issues and prolong the life of your Cat 3116 engine.
