Hi, Chaparral

No, I haven't, but I very much appreciate the tip - thanks! I've got fairly big hands; was it hard to do? I'll be giving it a shot later today or tomorrow.

Top Storage Shelf Attachment Clip Replacement

Lakeeriesailor,
The space from which to approach the spots for reinserting the clips was very narrow. The shelf needs to be in the "down" position and the fabric divider between the compartment and the trunk area needs to be unsnapped. Next, the spring-loaded ends of the shelf must be raised to get to the clip receivers. I'm sure the articulating "hinges" that snap onto the shelf ends will work OK without the clips if you can't get them back in. I just would not store anything heavy behind the seats on that shelf. Once that shelf gives way, the microswitch that allows top movement will not work as designed. Good luck!

New Motor Markings -Z4 Hydraulic Connections Differ

Re: How to Remove your Soft Top.....56k Beware
by ****ah - Sat Nov 12, 2011 11:55 pm

use the version from old markings, trust me, Pipe the new pump up the same way as the old one was and you will be fine, The new markings are incorrect.
==========================


Found this post from a few years back concerning the difference between the 05 motor and the new one I just picked up form BMW. So on a Saturday afternoon with no one at BMW to answer my question, what have you guys done? Use the configuration from the old pump including the same wire connections as noted above or change the connections ports to the new markings.

Thanks for Shipkiller the removal was less challenging that expected. When you get to those two clips over the fender wells, take an old screw driver heat the end to make a small pry bar, worked great. My Dad make one years ago, has bailed me out some may time I cannot count. Great little pry bar, about 6 inched long with a narrow blade.

Back to the motor, any thoughts? Waiting for BMW or a post from the forum.

Hi, Pops

I'm sure that you've been answered on your question re connecting the hydraulic lines to your new top motor, but if not, here goes: As has been pointed out repeatedly in the forum, the port markings on the new motors do not match the ones on the old motor. You have two choices - one is to switch the hydraulic lines to match the new port designations; the other is to connect the ports the same way as on the old motor, but you then have to reverse the electrical leads!

Now, a couple of questions: Did your dad use the bent screw driver to remove the clips, or to replace them, or both? Also, in replaciing my top after motor replacement, I couldn't get the boot that covers the top's arms to lie up properly against the bodywork. I noticed when removing/replacing the top that the screw holes for the screws attaching the "hoop" to the body are elongated, except for the center hole. Is there a sequence in driviing the screws in the holes to either side of the center hole that will cause the hoop and its seal to lie up better?

Hi,

I'm Gene and yes I'm Papa to the grand kids who love to go beaming with the top down. I used this bent screw driver to remove the top, it dropped right back in with only a good push. Once I saw the scheme it was easy. As far as the screw alignment, start at the middle and work your way around. I had to tap the hoop into place with a piece of wood and a light hammer, other than that it was easy. As you tap that hoop in place the locations of the holes change as the circumference changes. I called BMW about the hydraulic lines, and yes your response is correct. The positive is marked on the hydraulic reservoir, it's reversed from the original installation. I connected everything, plugged the power in to made sure it went up with the up button. It would not go down since the switch against the rear panel of the drivers compartment was not made so I pulled the hydraulic release and everything was OK. My concern was a difference in the piston output between the two ports. Nothing would surprise me with the designers of this car. I connected then per BMW's tech bulletin and it's doing just fine. I used a little clear silicone as a sealant for that rubber seal at the base of the top, so far no leaks but God bless whoever has to do the next one. If this need replacing again, then I messed us the sealing on the motor shroud, no way this is going to leak. Once I finished the assembly I was then able to see into the area where the motor resided, no water now so I just need to keep an eye on it.

On to bigger and better things. Good luck!!

Z4 Soft Top Removal and Motor Replacement Procedures

Hi, Gene

Thanks for the response. I'm still a bit unclear about the use of the bent screwdriver; did you mean that you used it to replace the convertible top or the "top" that fits in the trunk to mask the trunk's contents from outside view? If you're talking about the convertible top, then how did you replace the plastic clips that hold the trunk "top" in place?

When I put the "hoop" back into place, I did start at the center, but didn't tap the "hoop" back into place. I wonder if that's my problem with the boot on the passenger side not fitting properly?

The clip I speak about holds the aluminum hoop at each end, they are located over each wheel well. I've attached a picture of the screwdriver for everyone, great little tool. Fits nicely into the center leg of the clasp, just a little force and it opens up to get that hoop loose.

As far as getting the four plastic retainer clips, at each end of the compartment floor there are spring loaded end caps. I put a flash light in the trunk to see where the slots are, kind of reached over the top with each clip and pushed them on place. It took me a few minutes to figure out the spring loaded end plate thing then even where these stupid things went. Make sure to get the open portion of the clamp towards the rod it grabs on, I think the opening goes inwards towards the trunk.

See if this helps.

Drop us a picture of that boot you're having a problem with. The top boot that is the last item to install is a bugger. I put a little paint thinner on the rubber to make is slide easier. Keep it away from the 3M Trim Tape. Yea a little challenging but it finally fit in OK. I did it a few times without the tape to see how it fit. Drop a picture so we can see it....

The trunk "top" is actually called the 'Compartment Floor'.

Gene, unlike some of the others reporting on this forum, I luckily had little trouble removing and replacing the "hoop" in the clips at its ends. But should there be a next time - which I'm sincerely hoping there's not - I'll keep the bent screwdriver in mind.

I'm beginning to understand what you're saying about replacing the plastic retainer clips in the "compartment floor" (thanks for the proper term, Shipkiller!); I may have to read it a few more times and study the photos closely. I've got the "compartment floor" out right now, and it should be easy to see how the little buggers go in.

Re the boot, I'll try to post some photos in the next couple of days; just so we're on the same page, it's that complicated rubber fitting that goes over where the top's arms are attached to the body. The driver's side one fits perfectly; it's the passenger side that's giving me fits. As for the 3M trim tape, the stuff didn't work for me at all. Any idea where to get the stuff/double-sided tape that was there originally?

On the cap front, cleaning is extremely important. I cleaned both the rubber and body with an organic and inorganic solvent. Try paint thinner to loosen the glue and simple green to get the dirt.

I see you are in Connecticut, I am from RI so I could always take a Sunday trip if you are not to far West. Let me know if I can help. If I have the state right I'll drop you my email address.

The clips are a blind assembly, need to visualize the area and feel your around.

Gene, where you asking if I'm in Rhode Island? If so, I'm not; I'm in the extreme southeast corner of Michigan on the shore of Lake Erie.

PDF's Missing

Hi
I am charging up the old ThinkPad as they may be on there. If not I can walk you through the problem spots via FaceTime if that works for you. Give me until the morning then I'll let you know if I still have the PDF's. It seems like I had them somewhere, just need to locate them. Hang tight for a day or so.

What happen, no power or slow to move? My problem was a plugged drain hole at the bottom of motor compartment causing the cover around the motor to take a gulp of water every time down. Corroded the motor totally. I have picture of the top out of the car for reassembly purposes so we should be able to get you going.

Where are you located?

Later,
Gene

Top Removal PDF's Found

These provide the general guideline without the written instructions. Once again I can walk through the process with FaceTime.

I'll put the reassembly pictures up shortly.

Let me know,
Gene
