The most relevant products for semi-truck fifth-wheel upkeep are pin pullers, lubricant, and lube plates—not complete fifth-wheel couplings. The Fengone puller is best for reaching a release pin, Lucas Oil and Schaeffer are lubricant options, and the World American and Mytee Products plates are alternatives for reducing metal-to-metal friction. Confirm plate dimensions and equipment requirements before buying; the supplied product details do not establish universal fitment.
| Product | Best For | Key Detail |
|---|---|---|
| Fengone Fifth Wheel Puller | Reaching the release pin | 32-inch detachable tool |
| Lucas Oil 5th Wheel Lube | Applying liquid lubricant | Described as waterproof |
| World American Lube Plate | Using a polyurethane disc | 32-inch listing; limited specifications |
| Mytee Products Lube Plate | Choosing a specified-size HDPE disc | 36-inch diameter, 5 mm thick |
| Schaeffer Moly Lube | Spray-on lubrication | Adhesive aerosol formula |
Fengone Fifth Wheel Puller
This puller is best for drivers who want to release a fifth-wheel locking pin from outside the coupling area. Its 32-inch reach is intended to help access hard-to-reach pins, while the J-hook is designed to grip the pin. The manufacturer describes the tool as solid steel with a chrome-plated finish.
The handle separates into two 16-inch sections for storage, and the listed maximum pull force is 200 pounds. A T-handle provides leverage. These features make it a practical choice for routine coupling and uncoupling tasks, rather than a replacement part for the fifth-wheel mechanism.
Limitation: This is a manual puller, not a locking-mechanism adjustment or inspection tool. Use the correct procedure for the specific coupling.
Lucas Oil 5th Wheel Lube
Lucas Oil 5th Wheel Lube is best for buyers seeking a liquid lubricant option for fifth-wheel contact surfaces. The product information says it lasts twice as long as grease, is virtually waterproof, and helps eliminate greasy mess on the chassis and air hoses. It may suit operators who want to reduce grease transfer around nearby components.
Choose this if those listed characteristics match your maintenance preference and the coupling manufacturer permits this type of lubricant. Follow the product label and the fifth-wheel maker’s lubrication instructions.
Limitation: The provided details do not specify application instructions, operating temperature range, or compatibility with every fifth-wheel model.
World American 32-Inch Lube Plate
This World American product is listed as a 32-inch polyurethane fifth-wheel lube disc with a retainer. It is best for buyers specifically considering a polyurethane plate instead of applying lubricant directly to the coupling. A lube plate can be an option for reducing friction at the coupling interface, subject to the fifth-wheel and trailer manufacturers’ requirements.
Compare its listed 32-inch size with the required dimensions for your setup before choosing it. The listing identifies the brand and product type but does not provide additional material thickness or fitment specifications in the supplied information.
Limitation: Because detailed specifications are limited, verify dimensions, retention method, and approval for your application before ordering.
Mytee Products 36-Inch HDPE Lube Plate
The Mytee Products plate is best for buyers who want a lube disc with dimensions and material specified in the listing. It is made from high-density polyethylene, has a smooth surface, is 5 mm thick, and measures 36 inches in outer diameter. The listed inner diameter is 5/16 inches.
The product is described as providing friction protection and eliminating the need for grease on the plate surface. Choose it over a less-detailed listing if the stated measurements match your coupling and trailer requirements.
Limitation: The 36-inch outer diameter may not suit every setup. Confirm fitment and installation requirements before use.
Schaeffer Moly Fifth Wheel Lube
Schaeffer Moly is best for operators who prefer spray application over a tube or pail. The 16-ounce aerosol is described as spraying evenly and leaving a thin, durable lubricant layer. Its adhesive qualities are intended to help it resist water washout and reduce clumpy buildup and overgreasing.
Choose this if ease of application and a spray-on format matter. The product information says the lubricant stays where it is sprayed, which may help limit mess during application.
Limitation: Aerosol application may not suit buyers who prefer a solid lube plate or another application method. Follow the can instructions and coupling manufacturer guidance.
Buying Guide: Choosing Fifth Wheel Accessories
Do you need a complete fifth wheel or a maintenance accessory?
These listings are accessories, not complete fifth-wheel couplings for semi trucks. A puller helps operate a release pin; lubricant and lube plates address friction; an adjustment tool is used to inspect or adjust locking mechanisms. If you need a complete coupling, verify that you are shopping for the correct component rather than an accessory.
Should you choose lubricant or a lube plate?
Liquid and aerosol lubricants provide applied lubrication, while a plate is a physical disc intended to protect the contact area. Consider the maintenance method required by your fifth-wheel manufacturer. Do not assume a plate and lubricant are interchangeable or that either is suitable for every coupling.
What dimensions and details should you check?
Compare a plate’s outer diameter, inner diameter, thickness, material, and retention method with the equipment specifications. The Mytee listing gives several measurements; the World American details supplied here are limited. Check product documentation and manufacturer instructions before purchase.
What matters when selecting a pin puller?
Consider reach, handle design, storage length, and how the hook engages the pin. The Fengone tool lists a 32-inch length and a two-piece design. A puller does not replace safe coupling procedures or inspection of the locking mechanism.
Frequently Asked Questions
Are these products complete fifth wheels for semi trucks?
No. They are fifth-wheel accessories, including a pin puller, lubricants, and lube plates.
Can a lube plate fit every semi-truck fifth wheel?
No universal fitment is established by these listings. Check the fifth-wheel and trailer specifications before selecting a plate.
Is a fifth-wheel puller the same as an adjustment tool?
No. A puller operates the release pin. An adjustment tool is intended to help inspect or adjust the locking mechanism.
Should I use grease with a lube plate?
Follow the coupling and plate manufacturers’ instructions. The supplied product details do not establish one lubrication procedure for all fifth wheels.
Which lubricant is designed for spray application?
Schaeffer Moly is described as an aerosol lubricant that sprays onto the fifth wheel. Read its label and follow equipment guidance.
