A 318 plastic spacer is a component in John Deere tractors. It is a plastic flyball spacer that is attached to the cam shaft gear assembly. When the engine gets hot, the flyball spacer spins on the camshaft gear, causing the engine to lose the ability to regulate RPMs and overspeed. Symptoms of a failing flyball spacer include over-revving and hunting. To fix this, the flyball spacer must be replaced.

What You'll Learn
A 318 plastic spacer is used in John Deere tractors
John Deere tractors are renowned for their reliability and performance, and the 318 model is no exception. This tractor is a popular choice among farmers and enthusiasts due to its versatility and durability. One of the key components that contribute to its smooth operation is the 318 plastic spacer.
The 318 plastic spacer is an essential part used in the John Deere 318 tractor, playing a critical role in maintaining the tractor's performance and longevity. This plastic spacer is typically found in the engine compartment, specifically associated with the fender or the flyball governor assembly.
When it comes to the fender assembly, the 318 plastic spacer acts as a structural component. It is used in conjunction with bolts and threaded nuts to securely hold the fender in place, ensuring it remains stable and does not move when the operator gets on or off the tractor. This application of the 318 plastic spacer helps maintain the overall stability and integrity of the tractor's body.
However, the more common reference to the 318 plastic spacer is in relation to the flyball governor assembly. The flyball spacer is attached to the camshaft gear and plays a crucial role in regulating the engine's RPM (revolutions per minute). It consists of five ball bearings that spin outward due to centrifugal force as the engine RPM increases, subsequently pressing on the governor linkage to control the throttle and maintain the desired RPM range.
Unfortunately, the plastic flyball spacer in the John Deere 318 tractors has been known to cause issues, leading to over-revving of the engine. When the engine warms up, the plastic spacer may slip or break, causing the engine to lose its ability to regulate RPMs effectively, resulting in excessive speeds. This issue has been observed in tractors with specific serial numbers and manufacturing years, and it can be addressed by replacing the plastic spacer with an upgraded version or a metal flyball spacer.

They are also known as flyball spacers
A 318 plastic spacer is also known as a flyball spacer. This component is found in tractors, specifically in Onan motors. The plastic flyball spacer is pressed onto the hub of the cam gear, and it is not generally available as a separate part. It is susceptible to slipping on the shaft and breaking. This issue can be addressed by finding an early-style metal flyball spacer, which is pressed onto the shaft with adhesive. Another solution involves adding an aluminium tab secured by a screw that taps into the housing and mates with the notch found on most P series governor assemblies.
Flyball spacers are associated with hunting and over-revving issues in tractors. Hunting refers to erratic engine behaviour, while over-revving involves the engine exceeding the desired revolutions per minute. These problems can be mitigated by using a screwdriver to hold the throttle arm in place or partially closing the choke. Additionally, a plastic "dog" fix has been suggested, where a plastic component shaped like one of the empty flyball slots extends into the notch, preventing the spacer from rotating relative to the cam gear and avoiding over-speed from a slipping flyball spacer.
The 318 plastic spacer, or flyball spacer, is an integral component in the functioning of tractors, particularly those with Onan motors. While it may encounter challenges, various solutions exist to address slipping and breakage, ensuring the tractor's optimal performance.

They can be used to fix loose outlets
Plastic spacers are a great way to fix loose outlets. They are an easy DIY solution that can be installed in just a few minutes. If you have a loose outlet, you may be tempted to simply loosen the screws to bring it forward, but this will leave the outlet unstable and unsafe. Instead, plastic spacers can be used to support the outlet and bring it forward, providing a professional finish.
There are a few different types of outlet spacers available. Stackable plastic shims and Unishim fasteners, for example, can be used when the outlet box is stable, while the RACO device leveling plate is better suited for when the outlet box is unstable. These spacers are installed around the device mounting screws between the back of the tabs and the front of the electrical box. It is important to note that the power should be cut before installing spacers, and the device should be removed from the electrical box, although the wires do not need to be disconnected.
Quick-fix spacers are another option for adjusting switches and outlets. These spacers can be twisted apart or folded up to get fine adjustments for devices such as light switches, receptacles, and dimmers. They are a fast and easy solution for backsplash electrical outlets, providing the necessary clearance for screws when installing devices on a hard surface.
Outlet spacers provide support for outlets when plugging in devices and help to prevent cracked or broken faceplates. They can also help to avoid violations of building codes, as recessed receptacles may not meet regulations. Overall, plastic spacers are a simple and effective solution for fixing loose outlets, providing both functionality and a professional appearance.

They are available in different materials, like nylon or polycarbonate
Plastic spacers are available in different materials, such as nylon or polycarbonate. Nylon spacers are highly durable and resistant to cracks, corrosion, and most chemicals. They are also non-conductive, making them excellent electrical insulators. This is crucial in electronic applications as it prevents the flow of electrical current between conductive elements, reducing the risk of short circuits. Nylon spacers are also lightweight, cost-effective, and can be used across many outdoor and indoor applications in the electronics, construction, and automotive industries.
Polycarbonate, also known as Lexan, is another material that can be used for plastic spacers. It is a strong and durable plastic that is often used as an alternative to glass or other types of plastic. Polycarbonate is known for its impact resistance, making it a good choice for applications where there is a risk of breakage or impact. It is also lightweight and easy to work with, which makes it a versatile material for creating custom parts.
The choice between nylon and polycarbonate spacers depends on the specific application and requirements. Both materials offer advantages in terms of durability, weight, and electrical insulation. Nylon spacers are preferred in applications where corrosion resistance, chemical resistance, and cost-effectiveness are important factors. On the other hand, polycarbonate spacers may be more suitable for applications requiring high impact resistance and optical clarity.
Plastic spacers, such as the 318 plastic spacer, are commonly used in various industries, including automotive and tractor manufacturing. For example, in a tractor engine, plastic spacers may be used to separate and align connected parts, ensuring proper positioning and functionality. These spacers can be found in different materials, each offering unique benefits to enhance performance and durability.
