INSTALLATION TIPS: GAS SPRINGS

 

BEFORE YOU BEGIN

 

Before ordering a new non direct-fit gas spring, gather the following information:

1. Determine the original spring’s overall length by measuring from the housing lower end mounting centre to the piston rod top mounting centre with the unit fully extended.

2. Measure stroke distance (difference between rod length when is full compressed and fully extended).

3. Determine the pressure needed for the new spring.

4. Check type of end fittings needed to replace the old unit.

5. Note year, make and model of the vehicle.

 

KEY CONSIDERATIONS

1. Always replace both gas springs to ensure top performance and to prevent twisting caused by uneven loading.

2. Internal nitrogen gas charge is typically over 330 Newtons; therefore the unit normally cannot be compressed by hand.

3. Before removing old gas springs, examine any fittings supplied to determine which components must be re-used.

4. Have someone to support the hatch, bonnet, boot or rear window while replacing the gas springs.

5. Gas springs must be installed in the same position as the original units.

6. Replace the gas springs one at a time.

7. Springs must always be mounted with the tube up in the closed position. This is vital to proper lubrication and smooth operation.

 

DISASSEMBLY

 

Procedure to remove gas springs equipped with end fitting dark composite socket with flat metal clip, or all-metal socket with wire safety clip:

 

Pictos_Gas-Springs-disassembly-1

1. A small flat-blade screwdriver will be needed to release the flat metal clip or wire safety clip.

2. Open the hatch, bonnet, hood, window or liftgate to maintain load on the existing spring(s). Do not attempt this repair without a second person supporting the hatch, etc.

3. If the piston-rod mounting is a composite socket, follow these steps:

  • Insert the blade of the screwdriver under the metal clip at about a 45-degree angle and slightly pry to dislodge the clip until you can pull the gas spring away from its attached ball stud. Do not fully remove the clip.
  • Repeat the process at the other end.

4. If the piston-rod mounting is an all-metal socket with wire safety clip, follow these steps:

  • Insert the screwdriver blade beneath the wire clip and unclamp from the neck of the fitting. Rotate and remove the wire clip while pulling it completely out of the fitting.
  • Repeat the process at the other end.

 

INSTALLATION

1. If gas spring is fixed with a composite socket, follow these steps:

  • Start fixing rod end connection (lower connector) of the gas spring first. To do this, place the opening of the end fitting on the top of the ball stud. No tool is needed.
  • Carefully press the end fitting connector onto the stud. Do not use hammer or vice grips. Slight hand pressure should be enough to secure the fitting
  • Repeat this procedure at the other end.

2. If gas spring is fixed with an all-metal fitting and wire safety clip, follow these steps:

  • Start fixing rod end connection (lower connector) of the gas spring first. To do this, place the opening of the end fitting on the top of the ball stud. No tool is necessary.
  • Carefully press the end fitting connector onto the ball stud.
  • Fully insert the straight end of the wire clip into the small hole located on the side of the fitting. Next, rotate the curved section and clamp it around the neck of the fitting. This will tightly hold it in place.
  • Repeat this procedure at the other end.
