Drive or Lead Leg is the leg that motor will attach to. Follow or Idle Leg is used for manual cranking and/or the leg that does not have a motor in a powered set. You will need a bar between legs to connect the Drive (motorized Leg) and Follow Leg. Trying to replace one leg you will need to be sure you have the same size and gear ratio to prevent legs from moving at different speeds.

Before replacing any parts, please read the following checklist
Check For Binding and Damage
• Your trailer legs should be cleaned and checked for debris on a regular basis. Sand and dirt will cause legs to bind. See "To Clean Landing Gear 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.
Fuses blown
• Circuit is overdrawn overloading the jack and it is drawing too much amperage • Gear Box of the jack is damaged causing the motor to overload
Check Weight Limit
• 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. • 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.
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 housing or motor gear box as this voids warranty.
Remove the top of the leg and run the lube down on the sides to flush out any debris.

MANUAL OPERATING INSTRUCTIONS
For manual operation of fifth wheel landing gear on a trailer not equipped with a 12VDC 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. • Keep hands and clothing away from moving parts.
To Extend:
• Attach the manual crank handle and crank until the inner tube is halfway to the ground. • 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. • Continue extending landing legs until pin box disengages from the hitch and the trailer’s weight is completely removed from the hitch. • When there is sufficient clearance between the pin box and hitch, move tow vehicle clear of trailer. Never drop trailer off the hitch. • Lower trailer until it is level. • 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.
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 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. • 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. • 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.

Frequently Asked Questions
I already have a motor or gear box can I buy one of your and use it with mine?
You will need to verify all measurements and parts before purchasing, we are not aware of what system you have and cannot give recommendations.
If your motor or gear box does not look like ours, it will not work with your current system. Motor and gear box are for normal RV and trailer usage, heavy duty trailers such as road equipment have different landing gear leg systems.
Your current motor RPM, speed, and capacity may not match this motor, this would cause uneven lifting of legs.
Your current gear box dimensions, mounting system and gear ratio may not match, this would not fit or cause uneven lifting of legs.
If you have a motor or reduction gear box with plastic gears, you would want to replace all motors and reduction gear boxes after verify all measurements and parts will fit your legs.
The landing gear motor part number looks different!
Venture was acquired by Lippert, parts may have old or new part #, it varies. Venture Part #'s M-PK9000/M-9000/M-9000-PK Lippert Part #LCI PN 142178
My motor and reduction gear box are good, I have cleaned my legs and checked for binding but I am still having problems.
You may need a new rebuild kit for the gears inside of the legs. To find if your legs have the same gears inside you would need to open the leg to compare.
You can not replace the gears of one leg without verifying they are the same gears, the legs will move at different rates causing them to be uneven.
