Welcome back to Colorado Springs Small Engine Repair! In this video, we will continue working on the Dewalt generator. If you've been following along, you know that we encountered a problem with ripped intake keepers and a bent valve. If you haven't seen the previous video, I'll link it here for your reference. Now that we have all the necessary parts, we will reinstall them, set the valves, and get this generator up and running again. So, let's get to work!

Problem Description: Ripped Intake Keepers and Bent Valve

Before we start the repair process, let's recap the problem we faced with the Dewalt generator. The intake keepers were ripped, causing damage to the valve. This resulted in a malfunctioning generator that needed immediate attention. In our previous video, we showcased the extent of the damage and explained the steps needed to fix it. Now, with all the required parts in hand, we are ready to tackle the repair process head-on.

Parts Needed for Repair

To fix the ripped intake keepers and bent valve, we needed a few specific parts. After thorough research and purchasing, we now have everything we need for the repair. These include brand new intake keepers, a valve retainer, rocker arms, head bolts, guide push rods, and several other hardware components. With all these parts ready, let's move on to the next step.

Checking and Replacing the Keepers

As we begin the reinstallation process, we notice that the keepers previously installed are worn out and won't catch properly. This is a vital observation, as working with worn-out keepers can lead to further complications. We swiftly remove the old keepers and compare them to the new ones we bought. The difference is apparent – the new keepers have a ridge, ensuring a secure fit. With caution, we place the new keepers in position using our thumbs. Surprisingly, they fit snugly into place without requiring a valve spring compressor.

Assembling the Rocker Arms

With the keepers successfully installed, it's time to focus on reassembling the rocker arms. We have a box of parts that includes the valve cover, spark plug, carburetor, and other components. Prioritizing the task at hand, we gather the necessary components and ensure that the rocker arms are correctly positioned. The parts are aligned as per our memory and reference pictures, ensuring the correct placement of bolts and guides. Once everything is in place, we move on to the next step.

Installation of Other Components

With the rocker arms securely assembled, we turn our attention to the remaining components. These include the valve shrouds, air filter, carburetor mount, and related parts. Carefully examining the parts and referring to our reference pictures, we meticulously install each component in its correct position. We make sure to tighten the hardware securely, guaranteeing optimal functioning once the generator is operational again.

Setting the Valves

The next crucial step in the repair process is setting the valves. Proper valve adjustment is vital for the generator's performance, and we need to adhere to specific measurements. Using a feeler gauge, we confirm the required valve clearance – 0.004 inches for the intake and 0.006 inches for the exhaust. To achieve the perfect clearance, we set the engine to Top Dead Center (TDC) and adjust the valves accordingly. With patience and precision, we tighten the lock nuts to secure the adjusted valves.

Starting and Testing the Generator

With the valves set, it's time to start the generator and put our repairs to the test. We follow the necessary steps to initiate the generator's startup, ensuring the choke is appropriately set. Keeping safety precautions in mind, we are prepared to stop the generator if any issues arise. Thankfully, the generator starts without any complications, indicating that our repairs have been successful. We let it run for a while, allowing it to warm up and stabilize.

Final Checks and Maintenance

After running the generator for a sufficient amount of time, we proceed with the final checks to ensure everything is in order. We inspect the valves once again to ensure they have maintained their clearance. Additionally, we take the opportunity to perform any necessary maintenance, such as changing the oil and inspecting the spark plug.

Conclusion

In conclusion, our repair journey for the Dewalt generator has come to an end. We successfully addressed the problem of ripped intake keepers and a bent valve, meticulously replacing the damaged components and setting the valves correctly. Through careful attention to detail and methodical work, we were able to bring the generator back to optimal working condition.
