If you own a Road Glide, you know that it is essential to keep your motorcycle running smoothly. One of the most critical components of your Road Glide is the primary oil. The primary oil is responsible for lubricating the primary chain, clutch, and transmission. In this section, we will discuss the functions of primary oil, types of primary oil, and how to choose the right viscosity for your Road Glide.

Functions of Primary Oil

The primary oil performs several critical functions in your Road Glide. It lubricates the primary chain, clutch, and transmission, which helps to reduce wear and tear on these components. It also helps to keep the clutch cool, preventing it from slipping and causing damage to the engine. Additionally, primary oil helps to keep the transmission gears and bearings clean, which helps to prevent premature wear and failure.

Types of Primary Oil

There are two types of primary oil: synthetic oil and conventional oil. Synthetic oil is made from chemical compounds that are designed to provide better performance and longer life than conventional oil. Conventional oil, on the other hand, is made from crude oil and is less expensive than synthetic oil. Both types of primary oil can be used in your Road Glide, but synthetic oil is preferred because it provides better performance and longer life.

Choosing the Right Viscosity

Choosing the right viscosity for your primary oil is essential to ensure that your Road Glide runs smoothly. Viscosity refers to the thickness of the oil. The thicker the oil, the higher the viscosity. Different Road Glide models require different viscosities of primary oil. You can find the recommended viscosity for your Road Glide in the owner’s manual or by consulting with a mechanic. It is essential to use the recommended viscosity to ensure that your Road Glide runs smoothly and to prevent premature wear and tear on your motorcycle’s components.

In conclusion, the primary oil is a critical component of your Road Glide. It performs several essential functions, including lubricating the primary chain, clutch, and transmission. There are two types of primary oil: synthetic oil and conventional oil, and it is essential to choose the right viscosity for your Road Glide to ensure that it runs smoothly. By following these guidelines, you can keep your Road Glide running smoothly and prevent premature wear and tear on your motorcycle’s components.

Primary Oil Maintenance

Proper maintenance of the primary oil in your Road Glide is crucial for the longevity and performance of your motorcycle. In this section, we will cover the basics of primary oil maintenance, including checking the oil levels, when to change the oil, and the tools required for an oil change.

Checking Primary Oil Levels

Checking the primary oil levels is a simple process that can be done at home with basic tools. First, make sure your motorcycle is on a level surface and the engine is at operating temperature. Next, locate the oil level dipstick on the primary cover and remove it. Wipe the dipstick clean, reinsert it, and remove it again to check the oil level. The oil level should be between the two marks on the dipstick. If the oil level is low, add the recommended primary fluid to bring it to the correct level.

When to Change Primary Oil

According to the service manual, primary oil should be changed every 5,000 miles or once a year, whichever comes first. However, if you frequently ride in extreme conditions, such as high temperatures or dusty environments, you may need to change the oil more frequently. Signs that your primary oil needs to be changed include a burnt smell, dark color, or metal shavings in the oil.

Tools Required for Oil Change

Changing the primary oil in your Road Glide requires a few basic tools, including a T27 torque bit, socket wrench, and oil catch pan. It is also recommended to have a service manual or owner’s manual on hand to ensure you are using the correct oil and oil capacity for your specific model.

In summary, maintaining the primary oil in your Road Glide is essential for optimal performance and longevity. By following these simple steps and using the correct tools, you can easily check your oil levels and change your oil as needed.

Changing the primary oil on your Road Glide is a simple process that can be done in your garage with a few basic tools. Here is a step-by-step guide to help you change your primary oil.

Draining the Old Oil

The first step is to drain the old oil from your primary case. Locate the drain plug on the bottom of the primary case and place a drain pan underneath it. Use a 5/8 inch socket to loosen the drain plug and let the old oil drain out. Once all the oil has drained, clean the drain plug and replace it.

Cleaning the Primary Case

With the old oil drained, it’s time to clean the primary case. Use a clean rag to wipe down the inside of the primary case and remove any debris or dirt. This will help ensure that your new oil stays clean and free of contaminants.

Replacing the Gasket

Before refilling your primary case with new oil, it’s important to replace the primary cover gasket. This will help prevent any leaks and ensure that your new oil stays in the primary case. Use a gasket scraper to remove the old gasket and clean the surface where the gasket sits. Place the new gasket in place and tighten the bolts.

Refilling with New Oil

Now it’s time to refill your primary case with new oil. Use a primary funnel to pour the new oil into the primary case. Be sure to use the correct type of oil for your Road Glide. Check your owner’s manual for the recommended oil type and amount. Once you have filled the primary case with oil, replace the filler cap and start your engine. Let it run for a few minutes to circulate the new oil.

By following these simple steps, you can change the primary oil on your Road Glide and keep it running smoothly. Remember to always use a new gasket and the correct type of oil for your motorcycle.

Primary Oil and Clutch Performance

Impact on Clutch Slip

When it comes to the clutch performance of your Road Glide, primary oil plays a crucial role. The primary oil is responsible for lubricating the primary chain and cooling the clutch. The clutch plates rely on the primary oil to keep them cool and prevent them from slipping.

If the primary oil is not changed regularly or if the wrong type of oil is used, it can lead to clutch slip. Clutch slip occurs when the clutch plates do not engage properly, causing the engine to rev without transferring power to the rear wheel. This can be a dangerous situation, especially when riding at high speeds.

Choosing Oil for Best Clutch Performance

To ensure the best clutch performance, it is important to choose the right type of primary oil. When selecting primary oil for your Road Glide, it is recommended to use a high-quality oil that is specifically designed for use in wet clutch systems.

Some oils contain friction modifiers that can cause clutch slip, so it is important to avoid these oils. It is also important to choose an oil that is compatible with your clutch plates. Consult your owner’s manual or a trusted mechanic for recommendations on the best type of oil for your Road Glide.

In summary, the primary oil is a critical component for the clutch performance of your Road Glide. Choosing the right type of oil and changing it regularly can help prevent clutch slip and ensure a smooth ride.
