Slide Out, Grease Up: Camper Care And Maintenance

When it comes to camper slide lubrication, there are a variety of opinions and techniques. Some people believe that lubricating slide-outs is unnecessary and may even cause harm by attracting dirt and grit. Others argue that proper maintenance, including lubrication, is essential for ensuring reliable operation. The type of lubrication used is crucial, as thick, oily lubricants can attract dirt, grime, and other elements that can cause problems over time. Dry lubricants, on the other hand, create a protective film that repels these harmful substances and are recommended by many RV owners and technicians.

Dry lubricants vs. regular grease

Lubrication is essential to ensure the smooth functioning of mechanical parts. The improper use of lubricants can cause mechanical parts to wear out and fail, increase power usage, and create annoying sounds. There are two main types of lubrication: wet and dry (or solid). This article will focus on dry lubricants and compare them to regular grease (a type of wet lubricant) to determine which is better for camper slides.

Dry lubricants, or solid lubricants, are materials that can reduce friction between two surfaces sliding against each other, even when in the solid phase. They do not require a liquid oil medium to function. The two main dry lubricants are graphite and molybdenum disulfide, which can operate at higher temperatures than liquid or oil-based lubricants. Dry lubricants are often used in applications such as locks or dry-lubricated bearings. They can also be used in vacuum conditions, like in space vehicles.

Advantages of Dry Lubricants:

• Dry lubricants do not attract dirt, grime, sand, or dust like regular grease does.
• They create a protective film that blocks contaminants from forming on rails and gears, helping them last longer.
• Dry lubricants remove moisture, which can harm mechanical mechanisms if left untouched.
• They are suitable for high-temperature conditions where liquid lubricants typically fail.
• Dry lubricants are ideal for reciprocating motion, as they do not escape like liquid lubricants, preventing fretting, corrosion, and galling.
• They are useful for chemically active surfaces, such as polymers and ceramics, where specific lubricant additives have not been found.
• Dry lubricants are excellent for extreme contact pressures due to their lamellar structure, resulting in high bearing loads and low shear stress.

Grease is a type of wet lubricant that adheres well to mechanical parts. It tends to last longer than oil and helps keep dirt out by acting as a sealant. Grease is suitable for low-speed and low-load applications, especially in open or enclosed gear systems. It has a cooling effect, which helps dissipate heat generated by friction.

Disadvantages of Regular Grease:

• Grease can compromise the lubricant if a lot of particulate matter gets into it.
• It is thicker than oil and can be challenging to form an effective coating on mechanical parts.
• Cold grease can be equivalent to running with no lubrication, increasing power consumption and creating annoying sounds.
• Grease is not suitable for high-speed applications due to its higher viscous drag compared to oil.
• Excess grease can cause agitation, viscous drag, and power loss, especially in enclosed systems.

For camper slides, dry lubricants are generally a better choice than regular grease. They prevent the attraction of dirt and grime, which can cause potential damage to the slide-out mechanisms. Additionally, dry lubricants remove moisture and protect against corrosion. However, it is important to note that dry lubricants may need to be reapplied more frequently than regular grease. Regular grease, on the other hand, may be suitable for low-speed and low-load camper slide systems but can lead to issues with excess grease and contamination. Therefore, when deciding between dry lubricants and regular grease for camper slides, dry lubricants are often the preferred option to ensure smooth and efficient operation.

How often to lubricate

Lubricating your camper slide-outs is an important maintenance task that ensures smooth and trouble-free operation. The frequency of lubrication depends on various factors, including the type of slide system, usage patterns, and storage duration. Here's a detailed guide on how often to lubricate your camper slides:

Types of Slide Systems

Different manufacturers use different slide systems, and the lubrication requirements can vary. The most common types are rack and pinion systems and hydraulic systems.

Rack and Pinion Systems

The rack and pinion system is the oldest and most common type. It consists of a rack, which is the support that extends under the slide, and a metal track with teeth driven by a pinion gear rotated by a motor. Lubrication is typically required for this type of system.

For rack and pinion systems, it is recommended to lubricate the slide-outs at least twice a year. This includes cleaning the components and applying a light coating of lubricant to all gears, slides, cables, and rollers. However, if the slide-outs are in frequent use, it may be necessary to lubricate them more often, such as every two months or once a month.

Hydraulic Systems

Hydraulic systems are often used on larger, heavier slides. These systems are operated by a hydraulic pump and pressurised lines rather than an electric motor. For hydraulic systems, the lubrication requirements may differ.

If you have a hydraulic system, you may only need to apply a small amount of lubricant to the pivot joints once a year. However, it is important to regularly check the fluid levels and inspect all hydraulic lines and fittings for leaks.

Usage Patterns and Storage

The frequency of lubrication can also depend on how often you use your camper and how long it is stored between trips. If you are a full-time user and operate your slide-outs frequently, lubricating them every couple of months is recommended.

However, if you store your camper for extended periods, such as four to six months or longer, the lubrication schedule may differ. In this case, it is advisable to lubricate your slide-outs at the beginning and end of the storage period. This helps protect the metal parts from rust and corrosion during storage.

Seals and Gaskets

In addition to lubricating the slide mechanisms, it is important to maintain the seals and gaskets surrounding the slide-outs. These rubber components should be cleaned and treated with a rubber seal conditioner or spray to prevent premature decaying, drying, and cracking.

For seals, it is typically recommended to apply the conditioner or spray every eight weeks to keep them supple and prevent damage. It is also crucial to inspect the seals at least twice a year for any imperfections or leaks that could allow water to enter.

Choice of Lubricant

When lubricating camper slides, it is essential to choose the right type of lubricant. Dry lubricants or dry silicone-based lubricants are often recommended because they do not attract dirt and grime, which can cause damage to the mechanisms over time.

Avoid using thick, oily lubricants, as they tend to attract and hold dirt, grit, and other elements that can interfere with the smooth operation of the slide-outs. Always refer to your owner's manual or the manufacturer's recommendations for specific lubrication requirements and intervals.

How to lubricate

To lubricate your camper slide, you'll first need to clean the components to be lubricated. Any exposed parts, such as geared racks, cables, and support rams, should be free of debris before lubrication. You can use a brush or cloth to wipe away any dirt or grime.

Once the components are clean, it's time to apply the lubricant. You can use a spray lubricant or a dry powdered lubricant designed for RV slides. Spray or apply the lubricant to all gears, slides, cables, and rollers. Be sure to move the slide in and out to access the entire length of certain components and ensure they are adequately coated.

It is important to note that you should avoid using thick, oily lubricants as they can attract dirt and grime, leading to potential damage to the slide-out mechanisms. Instead, opt for a dry lubricant that will create a protective film and help repel dirt and grime.

The frequency of lubrication depends on the usage of your camper. If you use it frequently, lubricating every couple of months is recommended. However, if you store your camper for extended periods, you may need to lubricate more often, such as before storing it for the season and again when you take it out of storage.

Additionally, don't forget to lubricate the seals surrounding the slide-out. These rubber seals can be treated with a rubber seal conditioner or even baby powder to keep them flexible and functioning properly.

Maintenance and repair

Lubrication

Slideouts need two kinds of lubrication. The tracks and sliding mechanism should be lubricated with a product like Protect-All Slide-Out Dry Lube, CRC Power Lube, or Thetford Premium RV Slide Out Lubricant. These products dry without attracting dust and dirt and serve as rust inhibitors.

You can also use a dry powdered spray that coats your rails and gears with a dry film. This film will keep rust, dirt, and corrosion from entering the gears or damaging your rails. However, you should avoid thick, oily lubricants as these attract dirt and grime, which can cause potential damage to your slide-out mechanisms.

Frequency of Lubrication

Slideouts should be cleaned and lubricated at least twice a year, or every two months during use. They should also be lubricated before storing your camper and after you prep your rig for the spring.

Seals

The rubber sealing gaskets and wipers should be treated regularly with a product like Protect-All Slide-Out Rubber Seal Treatment or 3-IN-ONE RVcare Rubber Seal Conditioner. This helps keep the rubber flexible and protects it from UV degradation. Seals should be cleaned and treated every two months during use and again before storing your camper for the season.

Maintenance

In addition to lubrication, there are some other maintenance requirements for trouble-free slideouts. When cleaning the components, perform a thorough inspection looking for any damaged mechanical components, leaking hydraulic lines or fittings, loose or damaged electrical connections and wires, loose or damaged pulleys, and uneven wear on tracks.

The seals surrounding the slide-out are critical for weatherproofing your camper. Check for tears in the seal. If you have a hydraulic system, check the fluid level and all hydraulic lines and fittings for leaks. Remember that if you are doing any work with the hydraulic system, it is under pressure.

It is a good idea to run the slide in and out a couple of times, watching for even extending and retracting of the slide. When needed, have adjustments made. An out-of-adjustment slide will cause extra wear and stress on the slide. Listen for grinding, squealing, or any noise that is not normally heard.
