Understanding the Basics of a Pull Start Mechanism
Whether you are starting a lawn mower, a generator or any other small engine-powered device, the pull start is an essential component to get your machine up and running. A pull start mechanism consists of a rope wound around a spool and a coiled spring that gets tensioned when the rope is pulled. When you pull the rope, it turns a small cog known as a pulley that is connected to the device’s flywheel, therefore, turning the engine over. The mechanism can experience wear and tear over time, leading to various issues such as a pull start that won’t retract. Here’s a step-by-step guide on how to fix the problem.
Before undertaking any repairs, it’s important to ensure that you have the right tools for the job. You will need a socket set, needle-nose pliers, screwdriver, penetrating oil, and a replacement cord if necessary. Also, be sure to check the manufacturers guide for any specific instructions for your device. With everything in place, let’s get started!
The first step is to remove the starter housing from the device. This can be done by undoing the bolts that hold it in place. You will typically find four bolts- two on the top, and the other two on the bottom. Once the bolts have been removed, carefully slide the starter housing off the engine. This will give you access to the pull cord and the recoil spring that is behind the pulley.
Before you start inspecting parts, it’s important to take a picture of the mechanism before disassembling it and to pay close attention to the positioning of the parts. This will ensure that everything is put back together correctly at the end of the process. Now, carefully remove the recoil mechanism by unscrewing any screws or bolts holding it in place.
The next step is to check the condition of the rope. In most cases, a frayed or broken rope is the cause of the problem. If the rope is in a good condition and the problem persists, then a spring that has jumped off the mechanism’s housing or a broken spring may be to blame. If this is the case, replace the spring with a new one and put it in place.
After replacing the rope or spring, you’ll need to re-tension the recoil mechanism before reassembling everything. Wind the cord back into the starter housing; be sure to avoid kinks or twists. Now, hold the pulley in place and then release the cord so that it can wind back onto the starter spool. As the cord rewinds, you should feel the tension on the recoil spring.
Finally, it’s time to reassemble everything back to its original position. Put the starter mechanism back in place, tighten any screws and bolts, and then slide the starter housing back to its original position. Thread the handle onto the cord and insert it back into the housing. Give it a few pulls to make sure everything is working correctly.
By following these simple steps, you should be able to fix a pull start that won’t retract. It’s an easy job that requires only a few tools, and with practice, you can do it yourself and avoid having to pay costly repairs in the future.
