What You'll Learn

Cleaning the ram
Firstly, it is crucial to understand that the ram needs to be cleaned every time you use your trailer. This is because the ram is exposed to various elements such as dirt, sand, leaves, grass, and other debris while stabilizing your trailer. By cleaning it regularly, you prevent these particles from retracting back into the jack stand, which could potentially cause issues.
To clean the ram, start by spraying it with a suitable lubricant, such as WD-40. You can also use other lubricants, such as silicon spray or specific jack lubricants, depending on the manufacturer's recommendations. Spray the lubricant generously onto the ram, ensuring that it reaches all exposed parts.
After applying the lubricant, use a soft microfiber cloth to wipe the ram clean. Be gentle and thorough, ensuring that you remove all dirt and residue. Pay close attention to the crevices and joints of the ram, as debris tends to accumulate in these areas. You can also use a small brush or cotton swab to reach tight spaces and thoroughly clean them.
Once you have wiped down the ram, inspect it for any remaining dirt or grime. If necessary, reapply the lubricant and wipe it down again until the ram is completely clean. Additionally, remember to clean the base of the jack, even though it doesn't retract into the stand. This will help maintain the overall cleanliness and functionality of your trailer tongue jack.
Finally, allow the ram to dry completely before retracting it or using the trailer. This ensures that any remaining lubricant evaporates or is absorbed, leaving the ram well-lubricated and protected. By following these steps, you can effectively clean the ram of your electric trailer tongue jack, ensuring its smooth operation and prolonging its lifespan.

Using WD-40
Lubricating your electric trailer tongue jack is essential for keeping it in good condition. WD-40 is a popular choice for this task due to its versatility and effectiveness. Here's a step-by-step guide on how to use WD-40 to lubricate your electric trailer tongue jack:
Before you begin, ensure you have the necessary materials: WD-40, a soft microfiber cloth, and some towels or a yoga mat to place underneath the jack for comfort and to catch any drips. It is also important to clean the jack before lubricating it, so have some baking soda and water ready to create a cleaning solution.
First, prepare the electric trailer tongue jack by extending it as far as possible. This will give you better access to the areas that need lubrication. If your jack has been exposed to the elements, it is important to clean it thoroughly before applying any lubricant. Use a soft microfiber cloth and the baking soda solution to wipe down the jack, removing any dirt, debris, or corrosion.
Once the jack is clean and dry, it's time to apply the WD-40. Spray the WD-40 generously onto the jack, focusing on the areas where the handle attaches to the pin or screw.

Lubricating gears
Lubricating the gears of an electric trailer tongue jack is an important part of maintaining the mechanism and ensuring its smooth operation. Here is a step-by-step guide to help you through the process:
First, it is essential to identify the type of jack you have and refer to the manufacturer's instructions or recommendations. Some jacks, like the Ultra-Fab Electric A-Frame Jack, have specific procedures for lubrication. It is also important to consult the manufacturer's guidelines to avoid voiding any warranties.
Before beginning the lubrication process, ensure that the jack is stable and secure. You may need to extend the jack to gain access to the gears and other components. For example, to grease the gears of the Ultra-Fab Electric A-Frame Jack, you need to extend the jack until the grease fitting is aligned with the hole in the outer tube.
Next, gather the necessary tools and lubricants. Some jacks may require specific types of grease or oil, such as chassis lube or gear oil. It is important to use the recommended lubricants to ensure compatibility and avoid potential damage.
Once you are ready to lubricate the gears, start by removing the fuse from the fuse holder. This safety step will help prevent any accidental activation of the jack during the process. Then, proceed to remove the gear cover, which is typically secured with screws. Be sure to keep the screws in a safe place so you can reinstall the cover later.
With the gears exposed, it's time to apply the lubricant. Using a grease gun or another suitable applicator, apply a moderate amount of grease to the gears. Be careful not to over-lubricate, as excess grease can attract dirt and debris, leading to potential issues. Work the grease into the gears, ensuring that all moving parts are adequately coated.
After lubricating the gears, carefully wipe away any excess grease from surrounding areas. Then, reinstall the gear cover and secure it with the screws you removed earlier. Finally, replace the fuse in the fuse holder.
