King Shocks Oil Refilling On 2.0 and 2.5
« on: June 06, 2010, 04:56:17 PM »
Here is some information on refilling king shocks. I though I would share with the people on this forum. Hopefully this information will be useful for someone. 8) 8) 8)

The proper shock oil refilling on the 2.0 and 2.5 smoothies and coil over king shocks. (Remote and Piggyback Reservoir)

Notes: Begin steps after the shock is disassembled and empty of oil
REMEMBER TO ALWAYS TAKE THE PRESSURE OUT OF THE RESERVIOR BEFORE DISSASSEMBLY ON THE SHOCK.
1. First, charge the reservoir with 50 PSI of nitrogen. This will bottom out the floating piston inside of the reservoir. By doing this, the shock will be filled with the correct amount of oil.

2. Next, take the shock and place it upside down in a vise (if your shock has a remote reservoir, let it hang down, this is a non-issue for shocks with a piggyback reservoir).

3. Now fill the shock until the oil level is a 1/2" from the snap ring groove (for 8", 10", and 12" stroke shocks) and fill until 1" from the snap ring groove (for 14", 16", and 18" stroke shocks)
        *   For remote reservoir shocks, let the reservoir hang down and tilt the shock towards you at a 20 degree angle. This will allow the air to bleed out of the shock. Shaking the reservoir will also help to get the air out of the shock.
        *   For piggyback reservoir shocks,  press the palm of your hand over the opening of the cylinder. Then flip the shock right-side up for about 30 seconds to bleed the air out. As the air is bleeding out you will feel a slight vibration in the shock.

4. Once you have the shock bled, refill it until the oil level are back to as specified levels in step 3.

5. Now take the shaft assembly and reinstall it. Take the wiper cap and seal cap and move the towards the piston (so the shaft is at full extension).

6. Next, plunge the piston and seal cap assembly into the cylinder until the outer o-ring on the seal cap is just at the opening of the cylinder. As you are plunging the piston and seal cap assembly, make sure it is bleeding oil at the same time. If you have not bled any oil by the time you seat the o-ring on the rim of the cylinder, you will need to add oil and repeat this step. This step is a hole lot easier with the help on a second person!

7. After you bleed oil out of the seal cap, release the pressure out of the reservoir. Now plunge the seal cap further into the cylinder to expose the snap ring groove. Then install the snap ring.

8. To seat the seal cap against the snap ring, you can pull on the shaft to full extension or you can push down on the shaft, therefore raising the oil level and forcing the seal cap against the snap ring. Not much force is required to complete this step, so be careful. Clean out the excess oil from behind the seal cap. If this is not done, it will appear that the shock is leaking.

9. Now bring down the wiper cap and screw it onto the seal cap. You will have to pressurize the reservoir to 20 PSI, so there is resistance on the seal cap so the two will thread together.

10. Lastly, place some medium strength (blue) loctite on the set screw for the wiper cap and tighten it down.
