Installing shaft assembly into shock (floating piston set)

1. If the floating piston has not been removed and is located in the original location, fill the shock within 1-2” of the top of the cylinder. This will be dependent on the displacement of the piston assembly and the size of the rebound spacer. The longer the rebound spacer, the more displacement, the lower you should fill the oil. If the oil has not been removed, simply place the shaft assembly into the cylinder.

2. The piston and rebound spacer should be completely covered in oil. Place the rebound spacer in line with the ridge below the threads for the top guide. If oil is not covering the rebound spacer and equal with the ridge, fill until oil is equal with the ridge.

3. As the o-ring on the top guide passes this ridge, you will hear air escaping from the main chamber. Rock the top guide back-and-forth to allow as much trapped air to escape.
4. You can also push the shaft into the shock very slowly to push the last remaining air out of the shock. For the optimal performance, use a vacuum device to remove the last bit of air. This is common with professional racing teams, but will not degrade the performance of your shock any noticeable measure.
5. Finally, push the shock shaft down into the cylinder. This process allows you to check for any inconsistencies as the shaft travels down the cylinder and verifies the floating piston is placed correctly in the shock. If pushing the shaft into the shock gets progressively more difficult, the floating piston is possibly placed incorrectly.
6. Place the 2.98 x 0.85 O-ring into the top of the shock shaft.
7. Using the O-ring tool, push the oring back into the shaft.  
8. Refill the shock as described previously.
