If i can get this sorted, i have to admit it seems like a much better quality shock than the std one.
1. I always start by filling the shock up to the point on the inside of the shock where the threads start.
2. Then I ever so gently push the shock rod and piston down into the shock body filled with oil. Donít forget to soak the foam in the same weight oil.
3. Once the piston is bottomed out, I slowly move the piston up and down in the shock to make sure I have moved any trapped air bubbles to the top. Be careful not to bring the piston too far out of the shock body as you will suck air in and have to start over. You might cause oil to flow out the top in this process but that's ok.
4. Then just place on the threaded shock body cap over the piston rod and start to thread the cap into the shock body. Only thread the cap on about one turn or so. This will cause oil to bleed out but that's ok.
5. Then push the piston down to the bottom of the shock body while the cap is slightly threaded into the shock. If the piston rod does not come back out by itself, then screw the cap down a little more until the piston rod starts to move out on itís own.
6. Press the piston rod back down a couple of times to force out any excess oil.
7. Then thread the cap down into the shock body a little more. When the piston rod starts to automatically come out the top, stop and push the piston rod back down into the shock body a couple of times. If you thread the cap down too far, the piston rod will not go down into the shock body. If this happens, just back the cap out slightly until the piston is able to easily bottom out in the body.
8. Repeat this process over and over until the shock cap is treaded down finger tight and the piston rod will slowly back out of the shock body after you press it down into the shock.
It takes a little practice but it's not bad once you get the hang of it.
