I put the o-ring on the end of the hydraulic tubing, then pressed into the hydraulic ram. Make sure theres a little fluid on the o-ring.
Look at time 8:55 in this youtube... not the same ram, but same method of installing.
TopHydraulics has the best pump video... I refurbed my pump...
Been 3 summers since, but it was the first mod that I attempted on the Z4. I got lucky watching ebay and scored one from lithuania. You may find a better deal from a part out or breaker on ebay.
FWIW, I used new o-rings and at least one new clip for the reason that Robbi said. Dropped one and couldn't locate it and had the new ones from the repleacement harness kit. Wear your readers and use a pick to ensure that the old o-rings aren't in. New ones will satifyingly snap in when...
I forgot to add the fabric softener... The wife will be irate.
I drained the brake lines and refilled 18 months ago, so I'm good. Didn't know about this nag -- thanks!
1st drive of the season with mine -- and cleared all of the error codes from my winter hydraulic top refurb.
Good day to remember why I like this ride.
If you haven't already, it would be good to do something nice for the lady who cared enough to help the victim. It's not required, I'm sure, but it's such a wonderful thing that she's a person of character. If it were in the states, I'd be sending a gift card for dinner or such.
Horrible...
I noticed that the left boot lid is pulling down a bit too far, so a little adjustment of the kinematics there is needed. but nice to be out on a rare sunny afternoon yesterday.
Finished installing the refurbed pump from Top Hydraulics and Shell 2 reinstalled. I'm going to run with the boot and interior trim off for a few to check for any issues. Filled with top tier petrol from Costco and ready to wash, shine and protect tomorrow. Topped off the new hydraulic pipes...

And if you haven't installed spinning caps, you're just not on the level... :poke:
