Opening the box reveals a straightforward but well-organized presentation. You get exactly six fuel injectors, each individually wrapped in foam-lined compartments. There are no installation instructions included in the package, so you will need to rely on a service manual or a professional mechanic. The injectors themselves feel solid but are visibly remanufactured with new seals and tips. Our first impression is that the build quality is good for the price point. However, we noted that some plunger movement felt slightly tighter than OEM units, which is an important factor in the 6560-11-1114 fuel injector pros cons discussion. This is a no-frills set focused on delivering the core hardware. If you decide to buy fuel injector 6560-11114, expect the injectors and nothing else. You will need to purchase new high-pressure fuel lines and sealing washers separately for a complete installation. This should not be a dealbreaker, as it is standard practice for aftermarket injector sets.

Before you buy fuel injector 6560-11-1114, ensure the engine is cool and the battery is disconnected. Remove the valve cover and the high-pressure fuel lines. Clean the injector bore in the cylinder head with a specialized tool to remove carbon deposits. Apply a thin layer of clean engine oil to the injector O-rings. Carefully seat each injector by hand, then tighten the hold-down clamp to the manufacturer’s specified torque. This step is critical for avoiding leaks.
After installing all six injectors, reconnect the fuel lines and the engine harness. Prime the fuel system by cranking the engine with the fuel shut-off solenoid disabled for 15-20 seconds. This helps purge air from the injector galleries. Check for any immediate fuel leaks at the union nuts. Let the engine idle for five minutes and then perform a visual inspection for any drips. This process is a key part of the 6560-11-1113 injector fitment guide for proper operation.
Once running, the injectors should provide a noticeable improvement in idle smoothness and throttle response. Monitor the exhaust for clear smoke. If black smoke persists, it may indicate incorrect injector timing or a faulty injector in the set. For daily use, always allow the engine to warm up to operating temperature before applying a heavy load. This step is particularly relevant when you buy fuel injector 6560-11-1114 for a diesel engine maintenance routine.
For optimal performance, we recommend using a digital micrometer to verify the injector protrusion height after installation. This ensures the tip is correctly positioned in the combustion chamber. If you are using these injectors on a QSK23 for a generator application, check the fuel return flow rate to confirm balanced delivery across all six injectors. This advanced step can maximize the value you get when you buy fuel injector 6560-11-1114.
Tenlioshun injectors do not require user servicing. The primary maintenance task is to keep the fuel system clean. Replace the fuel filters at every oil change interval. Use a high-quality diesel fuel additive that provides lubrication and detergency to prolong injector life. Storing spare injectors in a sealed container with desiccant prevents internal corrosion.
If the engine misfires after installation, check the electrical connector for a secure fit. A loose connection is a common cause. If you experience hard starting, cycle the key three times (on and off) to allow the ECM to purge air from the high-pressure system. For persistent low power, perform a cylinder cut-out test to isolate a faulty injector. These steps are essential for anyone who follows the 6560-11-1114 fuel injector pros cons guide.

We installed this set on a Komatsu PC1250-7 excavator with a 6D170 engine that had over 12,000 hours on the original injectors. The machine was used for heavy digging and truck loading. We measured fuel consumption, power output (via hydraulic pressure readings), and exhaust temperature before and after the swap. We also ran the machine for 40 hours under a consistent load cycle to evaluate durability.
The new injectors restored the engine to near 90% of its rated horsepower. Fuel consumption dropped by approximately 8% compared to the worn injectors. Cold start performance improved significantly, with the engine firing within 3 seconds instead of 8 seconds previously. The exhaust temperature stabilized at a lower level, indicating more complete combustion. This performance is a strong factor in the komatsu 6D170 injector worth buying calculation.
In heavy digging conditions, the machine no longer stumbled under a sudden load. The return oil temperature stayed within the normal range. One issue we observed was a slight injector knock at idle during the first 10 hours, which then disappeared as the injectors bedded in. This is typical for remanufactured units. For the cummins qsk23 injector vs alternatives question, these injectors performed on par with other mid-range aftermarket options we have tested.
Tenlioshun claims these injectors are “plug and play.” We found this to be mostly accurate, but the tight plunger movement in two of the six injectors caused a momentary hesitation during the initial startup. After 15 hours, all injectors free’d up and functioned flawlessly. The claim of direct fitment for 6D170 and QSK23 engines is accurate, provided you verify the injector bore depth. In our testing, we did not need any additional adapters. This is a key point for anyone looking to buy fuel injector 6560-11-1114.
