Owners of excavators, tractors, and other similar machinery heavily rely on fuel injectors to precisely control the fuel injection process. However, issues such as poor injector performance, misalignment, or clogging can arise, often necessitating the replacement of the fuel injector. Upgrading for enhanced performance is frequently the best course of action. But how much does a fuel injector cost? And how do you go about replacing one?
Installation Cost and Compatible Injectors
Following a step - by - step guide can simplify the process of replacing a fuel injector. Usually, the installation cost is quite reasonable, ranging from $100 to $250. At FuelPartsPro, you can find a wide array of compatible fuel injectors that meet OEM quality standards. This includes options like DD15, E46 fuel injectors, or Duramax fuel injectors, among others. The replacement costs can vary significantly depending on different brands and models, but with our extensive selection, there's bound to be one that's perfect for your excavator or machinery model.
Inspection Frequency
Generally, fuel injectors should be inspected and adjusted every 500 - 600 hours. This regular check - up helps in repairing or replacing damaged components, ensuring the optimal performance of the diesel engine.
Replacement Steps
Replacing a fuel injector involves several steps and requires specific tools, such as needle - nose pliers and wrenches.
-
Locate and Remove the Return Pipe
Locate the black return pipe. Use needle - nose pliers or snap ring pliers to remove the pipe clamp and gently pull out the return pipe.
-
Loosen the High - Pressure Oil Pipe
Loosen the screw of the high - pressure oil pipe at the injector pump end. Then, use a wrench to remove the screw at the cylinder head cover end of the high - pressure oil pipe. It's crucial not to force the high - pressure oil pipe to avoid bending or breaking it.
-
Remove the Injector
Use a socket wrench to loosen the two nuts that secure the injector. Remove the cover plate above the injector and then carefully remove the injector. If the injector is difficult to pull out, gently pry the connection of the return pipe with the handle of a socket wrench to ease the removal. When removing the injector, be aware that there is a heat shield and copper washer underneath. The heat shield is at the bottom, followed by the copper washer, and the number of copper washer layers may vary depending on the machine model. If the heat shield and copper washer remain in the injector hole after removing the injector, reinsert the injector and tighten it before pulling out the heat shield. Check if the rubber edge of the heat shield is damaged, cracked, or burnt. If so, replace it with a new one. If there is no damage, place the heat shield and copper washers in the correct order on the new injector.
-
Insert the New Injector
Align the locator pin on the injector with the locator groove on the cylinder head and slowly insert the injector into the hole.
-
Install the Cover Plate and Secure Nuts
Install the injector cover plate with the smooth side facing down. Then, tighten the two securing nuts.
-
Reinstall the High - Pressure Oil Pipe
Reinstall the high - pressure oil pipe and tighten the nuts. Next, tighten the high - pressure oil pipe nut at the injector pump end.
-
Reconnect the Return Pipe
Finally, reconnect the return pipe and secure the pipe clamp.
