Bungee Kit and then some
 

I ordered the 5th bow bungee kit Part # 971F6-1ET0C, however that was replace with part # 971F61ET2A. Not thinking there would be much of a difference. The bungee kit arrived today and I have a number of extra parts that I am not sure what they are or where they go. The picture to the left is what came in the kit, the picture to the right is what I expected. Any ideas as to what the other parts are for?

If you look closely in the upper left corner of the kit you will see two springs attached to straps. I did look around with the top partially open and could see nothing that resemble those parts.

Thanks for your input.

Update: this is the correct part# and parts, there is a TSB on the convertible top that includes retrofit of many new/added parts to eliminate the top hitting the tonneau cover or snapping shut.

No instructions?
If I remember correctly, the old kit still was failing. Is the new kit redesigned to fix the problems with the first one?

No instructions included. From what I can find out searching the web, the bungee strength has been increased to close to 100 lbs of pull when fully extended. That sounds like a lot however, from just trying to stretch them and tugging on the existing ones they are stronger. So I am hopeful that they will work as intended.

As for the other parts, I can only guess that they have included any and all parts that my be need for either the 370z Roadster or the Murano Cabriolet. Again, just a guess.

I have viewed all the DYI videos by Top Hydraulics and they don't show anything like the extra parts include in the kit other then the bungee items and of course hydraulic pistons and lines.

Going to install the new bungees next week. I will let you know how they work.

See update in original post, when in dought do more research.

The answer is..... wrong bungee kit, the main / long bungees are to long by about 4 inches. The short bungees are correct. After starting the replacement on the driver side I had to re-attach the long bungee and use the new small one. I had enough strap left at the top of the old long bungee to punch a hole in it and reuse it as I would install new one. With just a new short bungee on the driver side the top no longer snaps shut, Still, what a pain in the arse.

I guess I will complete the install of the short bungee on the passenger side to balance things out. No need to even remove the old large bungee, just remove the top bolt, cut the short bungee strings, screw in the top of the new short bungee, punch the hole for the rivet in the strap where the old short bungee passed through, and install the rivet.

I'm also looking into ways to shorten the new large bungees, any ideas for a crimping tool that would hold the two cords together, currently the ends pass by each other and slip into a metal tube about 3/8 inches long. It is crimped down the middle with a cord in each side.

So part # 971F61ET2A is the wrong kit?

See update on original/first post. This is the correct 5th bow bungee kit, it is much more extensive then the kit it replaced.

The large bungees in that kit are way to long and as you can see from my first post it has a ton of unknown / unused parts. The only thing that appears correct is the very short bungees. So yes, it would appear that 5th Bow Bungee kit 971F6-1ET2A is not the correct kit. I just checked the packaging to verify that is the part # I received.

This should have been my first step not my last, I know better, I must of had a major brain cramp. See update on original post.

I am planning to call ProNissanParts.com and see what they know about the bungee kit and if there is anything they can do to get the correct kit. Since I had to use some of the part (cut off the short bungee before noticing length on the long bungee) I am probably out the cost of the kit.

I spoke with the a service tech at ProNissanParts.com. I did receive the CORRECT 5th Bow Bungee kit. However, there is a TSB on the top and all the extra parts are used to modify the install of the Bungee kit to correct any future problems with the roof hitting the toneau cover or snapping shut. The Service Tech is going to email me the 42 page install instructions for the new / updated kit. I am not sure I will take on the TSB bungee kit install, I may have to bite the bullet and take it to a dealer.

42 pages? :eek:
So all those extra parts are additional stuff we need to install? Looks like a good DIY post for anyone so inclined to do so! lol
Let us know how things turn out. :tiphat:

The service tech emailed me the Install instructions for the new bungee kit, its not 42 pages as he stated, its 33 pages. Still a very difficult and extensive upgrade to the bungees in the roadster top. I tried to upload however it exceeds the upload limit for PDF's. With the slight modification I made, (installing small bungees) and moving the long bungees as per the Top Hydraulic video the top is working as it should. I am going to wait and see how it holds up before I do anything else. I am starting to think this is a dealer install / upgrade.

Try converting pdf into pictures. That's how i've added Pdfs to this forum.

I broke the TSB instructions for the Bungee kit install into 3 parts, I will add two to this post and one more to the next.

Here is the third and final part to the 5th. Bow Bungee TSB file.

I'm in France and we cannot buy the kit in France dealer.

In your opinion, what is the best website to order the kit ?

I ordered the bungee kit from pronissanparts.com. they were very helpful and provided the TSB install documentation. However, nissanpartsdeal.com is also very good to deal with. Pronissanparts is located in Texas, and nissanpartsdeal is located in New Jersey.

So the old kit is # 971F6-1ET0C

and the new kit is # 971F61ET2A

Which one will fix the problem? Would someone please shed some lights? Thanks.

Thanks for all your hard work with this project. Please keep us informed as to how well it is working for you. It looks like a very tedious and complicated project so i hope it will be a good solution. I have the same issue with my 2014 being very loud and hitting the top also and am ready to order this new part # as soon as you can verify it is an adequate solution.


Thanks!

The old bungee kit is no longer available replaced by the new TSB kit which is much more extensive and looks like a dealer install item.

I wish I could give some feedback as to how it works after installing new bungee kit (fixing the roof hitting and snapping shut). However, I only installed the short bungees which did stop the roof from snapping closed. I messed around with the long bungees and screwed them up. I am left with either ordering the new bungee kit again and following the TSB install instructions or taking it to a dealer. Undecided at this time.

Ok I think i will just order the new kit and figure it out. Thanks for posting the TSB pdf info. I went through it yesterday and think i can get it done.

Hi mate, thanks also for posting all the info on the new bungee kit. Like many others, or do I say just about everyone’s, my deck lid hits the 5th bow and I was going to order the new kit and replace it myself, using the Top hydraulics very helpful video clip but when I read that some owners here on the forum said it took Nissan over a week to install the new kit part number I knew that the kit must be quite different from the original one. Here in Australia I have no confidence in letting my local Nissan dealer do this work. I may ring around Sydney at some stage to see if any dealership has carried this out, as I do not want my car to be the guinea pig.

Hi mate, I would be very keen to see how you get on with this
Good luck :tup:

Just waiting for it to come in. Maybe i will try to video the process and see if its something worthwhile that might help others.

Yes, that would be great but not that easy to I guess. Even just making good notes, video/photo any tricky bits or where the service bulletin was not real clear. I am sure there will be quite a few if not all of us that will need to do this task at some stage.

Cheers and good luck 🙂

Mine is scheduled to arrive this saturday. Probably wont get to it til the following weekend. I have too many other projects that need immediate attention.

Got my kit in. I will try to make this a project for next weekend.

I finally have some time to tackle this project this weekend. I was going over the instructions last night.... man, its alot of steps! Ill need to go over it a few more times to make sure everything is clear to me before I go cutting and drilling stuff. I suggest anyone installing the kit do the same!

Hello, first time caller, long time listener here.

I just did this repair on a 370Z in our shop and it is much more involved than the previous kits. I thank you majorly for providing the TSB.

The issue with this particular 370Z was the 5th bow hitting the edge of the storage compartment, not actually the tonneau. But it did come into contact with that.

There are a lot of parts to these tops, but the main thing I just wanted to say is that this kit, as of now, makes a big difference in the top operation right away by adding a spring which does the brunt of the pulling.

We've done quite a few of these with the older bungee repair kit in the past with mixed success. Sometimes it would only solve the rubbing mostly, but not fully. The spring on the new kit, once installed, really pulls the bow up and out of the way and when it stows it keeps everything nice and tight.

That sounds like great news for roadster owners! :driving:

Yes great to here of another successful installation of this new version of the bungee kit, there seams to have been a few carried out now. I am going to bite the bullet and order one from the US, half the price of what Nissan Aust want and then try and find a company who can do the job

New top!
 

Like many roadster owners, my car's been bedeviled with the top-hitting-tonneau issue. I've been experiencing it almost since I first got the car in 2017. I took it to the dealer almost immediately, and they replaced the bungees. But it didn't really do anything.
So, I was excited to read last year on this forum that Nissan engineers had come up with a new fix. I waited until my warranty was about the run out (because I figured that there'd be some "lessons learned" and experienced gained as the new TSB was implemented a few times.) Finally, last month, I brought my car in for the new bungees.
However, after an inspection, the service guys told me that the top's hinge had sheared. (See attached photo; it's on the passenger's side.) I have my suspicions that it was they who broke it, while they were carrying out the TSB. I mean, I'd never noticed a problem with the hinge. But I suppose I hadn't looked at it closely.
Anyway, the dealership decided that they'd replace the whole top. The retail cost of this was something like $19,000, but as it was under warranty, it cost me nothing. The top was replaced, and the problem is fixed. Of course, I do wonder if the new top has the old bungee technology, which is prone to eventual weakening and failure.
Bottom line is: Check your hinges! I assume a broken hinge could be welded for a lot less than $19K, if your car is out of warranty.
Cheers,
Steve

Lucky you the hinge broke under warranty.

In fact it is quite common in Z, and to make it worst Nissan doesn't offer replacement just for that part! :shakes head:

The new kit is more involved. It completely replaces how the bungees are configured and adds a new strap and spring that bolts to the frame.

Yes, and the worst thing is there's no instruction, so many people/installers have no idea what is the use of extra hardware.

Very simple steps as long as you have watched this video and have the proper tools.

Look at my DIY thread. I posted a link to the instructions with color pics.. :tup:

nice find on the colour instruction!! :tup:

TSB for 5th bow.
 

The TSB is very detailed but its not a simple install.
I would find a shop that works on convertibles to install it if you are not a good mechanic.
The instructions are very good, but there is some figuring out of routing of a few things that are not clear in the instructions.
I just finished mine and it completely eliminates the interference issue.
