Heb helaas geen foto's gemaakt, maar het wijst zich vanzelf.
Ik heb dit recept gevolgd.
Whilst the accumulators don't take long, critical thing is bleeding the system afterwards. Here's my write up :
You need :
17mm spanner
12mm spanner (can't remember, think it was 12mm, may be 11mm, one or the other.
)
10mm socket wrench
-jack up the rear of the car
-place tray under air cell you are going to remove to catch fluid spillage
-undo the 12mm union pipe connection (thin pipe) going into side of accumulator
-undo the 17mm strut hose, where it attaches to air cell (spray some WD40 over it first and leave for a few minutes before attempting to loosen)
- undo the 3 10mm bolts holding air cell legs on frame of car
- remove air cell
- plonk on new air cell
- tighten the 3 10mm bolts to hold the air cell tight
- connect the small hydraulic pipe, 12mm
- connect the strut hose, 17mm
- repeat procedure for other air cell
- then open bonnet and top-up hydraulic fluid to the max mark on dipstick (leave car up on jack at rear)
- then get under car, remove the 10mm bolt connecting the levelling control unit linkage to roll bar, and lift the linkage arm upwards
- start car and rev to 2500-3000 rpm
- crawl under car and move linkage up/down slowly, giving time for rear end to lower and rise (someone needs to hold revs at 2-3k whilst doing this)
- switch off car and undo the bleed screw on top of the control unit, half a turn, to release any air that is in system.
- retighten bleed screw, top up fluid again (making sure you only do this when linkage is fully down, i.e. car is not raised due to self levelling system, because at that time, fluid in reservoir should be low as it is all in the struts!)
- repeat linkage up/down procedure with car started and then finally reconnect linkage to roll bar, securing the 10mm nut.
The final procedure is crucial to bleed the system.
All done - remove jack, check fluid again, top up if required ! Easy peasy !!
There are no copper seals to replace or renew at the air cells. They are all at the strut end connections.
And of course, for safety, use jack stands under each end at the rear, with jack under diff. Don't rely on the jack alone.
