Suspension Accumulators
Accumulator Re-gassing
To re-fill the Nitrogen in the suspension accumulators; 1. Remove the accumulator 2. Install valve 3. Fill with Nitrogen
Removing the accumulator
To remove the accumulator: 1. Remove the wheel 2. Clean the working area so that a) you can see what you're doing, and b) the dirt does not get into the threads of the nuts & bolts 3. Apply suitable lubricant / (eg Penetrene) and let sit for a while to help release the bolts
Release the hose clamps around the rubber boots that protect(ed) the suspension piston. Unscrew the "cover" that joins the top of the accumulator to the rest of the suspension strut. Tis will likely need a pipe wrench (diameter of the cover is approx. 75 mmm) Unscrew the suspension strut. This will require a 36mm spanner. Please also note that the spanner can be no more than 8mm thick. Unscrew the 19mm nut that holds the accumulator to the lower A-arm Unscrew the 19mm that hold the upper A-arm in place and remove the bolt. As this bolt is quite long, you will also need to remove the front side wheel well /engine under cover.
Optionally, re-build the suspension strut
