Set the correct IFP depth:
For 267x89 mm shock size: 53 mm
For all other shock sizes: 49 mm
Mark the correct length on a plastic pipe or dowel. Use the pipe to slowly push the IFP to the correct depth inside the reservoir.
Measure from the top of the reservoir to the top of the IFP.

Thread the pump and Vivid Pump Adapter into the IFP reservoir cap. Pull up on the pump to seat the reservoir cap against the retaining ring.
31
Use the pump to pressurize the IFP reservoir to 200 psi.
Once you have pressurized the reservoir, remove the Vivid Air
Pump Adapter from the air fill port before removing it from the shock pump. Separating the pump from the adapter first will allow all of the air to escape from the reservoir.
You may substitute nitrogen if you have the proper fill equipment.

Align the shaft eyelet so it is parallel with the body eyelet, with the
Beginning Stroke Rebound knob in the orientation relative to the
IFP reservoir that you recorded for your shock.
38
Recall the number from the top of the air can that you recorded.
This will assist you with the proper alignment of the air can relative to the Beginning Stroke Rebound knob.
This number corresponds to a key slot in the air can that will engage the tab on the shaft eyelet, so that the shock will be installed on the bicycle with the air can in its original position.

Pour 3 cc of Maxima® Maxum 4 Extra 15w50 oil into the air can inner sleeve. Rotate the air can to spread the oil evenly on the inner surface of the sleeve.
Keep the air can positioned horizontally so the oil does not spill out.
Do not get oil on the air can threads.

Do not allow the seal head glide rings to become dislodged from the seal head during air can assembly. This can damage the glide rings. Push the glide rings with your finger as you install the air can to prevent them from getting pinched.
41
Spray isopropyl alcohol on the air can lock ring threads and shaft eyelet threads and clean them with a rag. Apply red threadlock to the lock ring threads. Install the lock ring over the shaft eyelet, then use the pin spanner to continue to turn the lock ring just until it starts to tighten. Remove the shock from the vise.

Position the pin spanner into the lock ring, then clamp the shock by the shaft eyelet into the vise, leaving just enough room for the spanner to rotate. Use the spanner to tighten the lock ring to
22.6 N.m (200 in-lb). Remove the shock and spanner from the vise.
There is a small amount of air can rotation available once the air can is seated in the key slot. To maximize clearance around the air can valve, rotate the air can so the valve is away from the
IFP reservoir. Hold the air can in this position as you tighten the lockring.
