WARNING Be sure your coach is fully supported and securely stopped before attempting to replace any items on the landing gear leg system.
BEFORE YOU PURCHASE
If your motor is making a clicking sound and the legs are not moving or will move very little check a few things:
Are the legs binding? Your trailer legs should be greased and checked for debris on a regular basis to prevent binding. The other reason legs will bind is if they have been bent, even slightly, will cause them to bind.

Have you added large amounts of weight to the trailer? Extra large appliances, extra water holding tanks, atvs, and etc. will add extra weight to your trailer check this to see if you are over a single motor systems limit.

Did the trailer come with one motor but really needs a dual motor system? Some trailer dealers will place a one motor system on a coach that actually needs a dual motor system in order to save money, again check the weight of the unit and compare it to what the motor can easily lift.

Before replacing any items please go through the following checklist

If your motor is making a clicking sound this is the safety clutch in the motor preventing damage to the motor.
This is not the gear box.
When clutch noise occurs, release the power switch.
Failure to do so will result in damage to motor and possibly other system components.

Check for binding
Your trailer legs should be cleaned and checked for debris on a regular basis.
Sand and dirt will cause legs to bind.

To clean landing gear legs
Extend landing legs as far as possible, clean drop tube and inner ram tube.
Coat exposed surface of tubes with silicone spray lubricant.
Coat inside of handle alignment tube with silicone spray lubricant.
Oil shaft bushing in gear box and leg gear heads with SAE 30 oil.
Lubricate gears in gear box and landing leg gear heads with extreme pressure grease.
*Do NOT open motor to lubricate as this voids warranty.

Check for damage to legs
Any damage to the legs such a bending or denting will cause binding.

Check power to system
Check that your batteries and power supplies are at full levels to prevent damage to the motor.
Check wiring connections at battery. Clean terminals with a solution of baking soda and water.
Cover with a thin coat of grease.
Check wiring harness fuse, if blown replace with appropriate fuse.

Do not exceed weight limit of landing gear system
Do not use the landings legs to lift the trailer during tire changes, axle work or trailer servicing (the trailer weight will exceed the capacity of the landing legs).
The landing legs are designed to stabilize a portion of the trailer’s weight.
Support the front end of the trailer with structural stands rated for the GVWR of the trailer.

Grease Landing Gear Legs

You will want to remove the top of the leg and run the lube down on the sides to flush out any debris.



SAFETY WARNING:
• Read, understand and follow all instructions before installing and using product.
• NEVER allow anyone unfamiliar with the operating instructions to use this product.
• Failure to follow these warnings and instructions can result in property damage and/or serious bodily injury.
• Class A Customs is not responsible for improper installation, use, or maintenance of this product.


The following items must be done before operating the levelers.
• Warn all persons to stand clear of vehicle.
• Keep hands and clothing away from moving parts.
• Park the vehicle on a reasonably level site. Check for rocks, holes, or other obstructions.
• Soft/spongy ground may allow levelers to sink. Levelers must be on firm solid ground or surface prior to operation.
• Insure area below and around leveler is clear of obstructions.
• Do not extend the slide-outs until coach is level.

• Never exceed rated capacity of landing legs.
• Do not use the landings legs to lift the trailer during tire changes, axle work or trailer servicing (the trailer weight will exceed the capacity of the landing legs). The landing legs are designed to stabilize a portion of the trailer’s weight. Support the front end of the trailer with structural stands rated for the GVWR of the trailer.
• Chock both sides of trailer wheels before operating landing legs.
• Both legs must touch the ground or the surface at the same time.
• Never drop the trailer off the hitch.
• Never attempt to lift or level without having both foot plates properly installed.
• When cranking jack or coupling trailer, secure trailer from rolling.
• These landing gear jacks are designed for vertical loading. Excessive side forces must be avoided.
• Never attempt to adjust the drop legs when the landing gear jacks are under load.
• Make certain the drop leg safety retaining pins are fully inserted through both sides of the inner tube and the drop leg tube before using the landing gear jacks.
• Owner or operator must never position any part of their body under any portion of the
jack or the load being supported or allow anyone else to be positioned under the load being supported. Disregard could cause property damage and/or serious bodily injury.
• Do not retract past the STOP label.
• Retract landing legs completely before towing trailer.


• Most switches are not ignition protected. DO NOT install these in areas which require ignition protected devices (such as battery or propane tank storage compartments). Only the Ignition Protected Switch is approved for installation in these compartments.

• Failure to follow these warnings and instructions can result in property damage and/or serious bodily injury.




POWER OPERATING INSTRUCTIONS
On a trailer equipped with a Venture Mfg. Co. 12VDC Power Kit follow the same procedures as “MANUAL OPERATING INSTRUCTIONS” except, operate the switch control to EXT (extend) or RET (retract) as indicated.

Power Kit is equipped with an overload clutch and a 30 AMP fuse. If fuse blows during normal operation replace fuse (located on the pink wire) with standard 30 AMP AGC type fuse.

Verify battery is fully charged before attempting further operation.

If clutch slips it may indicate you have reached the extend or retract limits of the jacks OR the trailer weight has exceeded the max rated load of the Landing Gear system.
Items stored inside/on the trailer can greatly affect the weight applied to Landing Gear system. If clutch consistently slips during normal operation, redistribute items stored in the trailer.

CAUTION
• When clutch noise occurs, release the switch. Failure to do so may also destroy
the clutch, in which case the entire power kit will have to be replaced.

• Potential damage to the trailer frame may occur if legs or power kits are operated
unevenly. Front of trailer must remain horizontal.

MANUAL OPERATING INSTRUCTIONS
For manual operation of fifth wheel landing gear on a trailer not equipped with a 12 VDC power kit, or if power is not available, proceed as follows:

• Drop Leg Operation: Disengage drop leg safety retaining pin to lower or raise foot plate to desired position, return the safety retaining pin making sure it is fully inserted through both the inner tube and the drop leg tube before using the jack.

• To Extend:
(1) Attach the manual crank handle and crank until the inner tube is halfway to the ground.
(2) Remove the safety retaining pin from the drop leg tube. Let the drop tube fall to the ground and re-pin in the nearest adjustment hole.
(3) Continue extending landing legs until pin box disengages from the hitch and the trailer’s weight is completely removed from the hitch.
(4) When there is sufficient clearance between the pin box and hitch, move tow vehicle clear of trailer. Never drop trailer off the hitch.
(5) Lower trailer until it is level.
(6) Remove and store crank handle.

• To Retract: Perform “To Extend” instructions in reverse. Be certain the landing gear legs are fully retracted; drop legs are re-pinned in the fully retracted position; and foot plate is higher than the lowest point of the trailer to prevent dragging. Remove and store the crank handle.

How does the reduction gear box go on? And will your box fit the unit I already have?

If your motor does not look like our motor it will not work with your current system. You may need a new reduction gear box and rebuild kit. To find if your legs have the same gears inside you would need to open the leg to compare.










This rebuild kit is for repairing the drive leg on 5th wheel landing gear
This kit is also used to convert an idle leg into a drive leg for a dual motor system

Diagram in pictures shows all included parts.

The hardest part of installing this kit is working in tight spaces. Your best route is to drop the leg out by unbolting the two bolts that hold the leg in. Once out it is a lot easier to work on and when your done you lift the leg back up and bolt it back in.



Your leg needs to have a 1/2 moon shaft to fit our reduction gear box or you will need a rebuild kit.






Be sure to place the black rubber stopper piece over the 1/2 moon shaft once you have the reduction gear box on the leg and use the screw provided to secure the stopper. 

You do not screw the box to the leg the cross bar will keep the box mounted on.

 
 



 Again use the screw provided to secure the cross bar on to the 1/2 moon shaft.

 Secure the idle leg, there will be no rubber stopper on the idle leg.






 What if I am using a motor to make the legs powered how do I hook the motor up?


The motor will attach to the reduction gear box and be secured with the two bolts provided. Be sure you correctly line the motor shaft with the crank shaft.


If you already have the legs but need to change your motor(s) and gear box(es) your leg(s) needs to have a 1/2 moon shaft to fit our reduction gear box or you will need a rebuild kit.


If you have a dual motor system you will need a rebuild kit, reduction gear box and motor for each leg. Due to different style motors if you have a different brand motor it is not advised to change just one motor at a time, the reason is the motors may lower/raise at different speeds causing damage to your trailer.












If you lose power you can manually crank a system with a motor attached.



I already have a motor can I buy one of your motors and use it with mine?

If you have a Venture M-9000 (M PK-9000) Motor then yes.

If you have an off brand or an ADTH motor then no. ADTH and other brands copied the Venture motor and most used plastic gears which wear down very easily. The motor speeds and different type of materials make them an unsafe match to use, you do not want one leg to go up or down faster than the other leg. This is the same problem with having a plastic gear box.
