Think I am getting the general picture on how to refill the preload adjuster reservoir but will still probably end up with oily hands and skinned knuckles when I attempt it at the weekend. One thing is still confusing me though and that's how to purge the air that will be in the line when it's reassembled. I understand the principle of winding in a lttle preload and then slackening the banjo to let the air out but there's no means of adding more fluid to take up the space left by the air as you can't refill the reservoir from the top. This means presumably that you will lose the effectiveness of the first few turns of the adjuster?
This really isn't that difficult of a task once you have done it for the first time.
When you disconnect the hose make sure it stays higher than the shock so that no fluid runs out of the hose. Fill the adjuster per the instruction linked to in prior post.
When bleeding the air out simply hold the adjustment unit higher than the shock, turn the knob in til resistance is felt then a 1/8 turn more. Hold adjuster unit with crescent wrench on the flats and loosen bolt that connects the hose. The fluid lose is minimal and any air left won't be noticeable.
The unit is designed so that there is always a little slack before resistance is felt. This is so the c-clip can be removed to take the unit completely apart. That is another story though.
If you can change plugs, then you can do this.
