STEP 37

Press the compensation bladder in the shock head cap. Do this with care until it fits completely in the groove that is inside the shock head cap.
Do all four of them and they should look like this.
At each shock head cap are two small holes. These hole have a purpose in the next steps and need to be half free as the compensation bladder is placed correctly in the shock head cap.
Now fill the shock with silicone oil. The manual states to fill them with 35 wt. But this is not the same thickness as 350 CS! So we start with the long ones and fill them with 200 CS until just under the edge of the shock body. For the shorter front ones you can use 350 CS.
Fill them all and slowly move the piston up and down (do not look above the shock absorber while moving the piston). Make sure that air bubbles trapped insode are rising to the surface by just letting them stand for a few minutes. This rim is an excellent shock holder.
Now hold the shock absorber body vertical by hand and move he piston slowly upwards into the shock body and hold it that way. Place the shock head cap and turn it two turns.
Now turn the shock head cap slowly further onto the thread.
Excessive oil will leave the two small holes in the shock head cap. Wipe this excessive oil away as quick as possible. Check the shock absorber by moving the piston. If you hear or feel air bubbles remove the cap and redo the sequence. Also check if no oil is leaving the top of the shock head cap. If this is the case redo the sequence. I had some difficulties where the compensation bladder was not gripped inside the shock head cap firmly and it fell into the shock absorber. After rebuilding it three times for one shock it finally worked OK.
