David, Kansas City will still have a few old school Auto Electric repair shops. Their bread and butter was always the repair/rebuilding of alternators, generators, starter motors and all other electric components. Look for an auto electric specialist and not a general car repair shop. Shaping brushes to fit your fifth bow top motor and installing them will be a quick and easy job for them. That motor is almost identical to power window and power seat motors. In addition to the radio controlled electric car motor brushes, you can also file down brushes from battery-powered tools (drills etc.). A good shop will almost certainly have a selection of brushes that can be adapted.

Check out amain.com. I purchased TRI4499NT. Had to file them down to fit in the plastic piece. I bought a couple in case one broke or in the future I have to change them again.

Thanks a lot Red for the info, I bought a few like you suggested, there is nothing down here in OZ, went to so many hobby stores.

How did your roof function after you replaced the brushes?

Cheers Mate

Remember the first time you opened your top? Even better than that! The time to open and close is very fast and smooth. Congrats on the purchase and good luck on the fix.

Im in the same boat. I just bought an 04 350Z and the top is a little lazy and doesn't always go all the way down. I see needing to repair this motor also, but can't see the photos. They are gone for some reason. Any help would be great!

Right - I've got all parts on order and should arrive in a couple of weeks. I'm going to attempt the fix and will record a video and post it (Assuming success!)

In the mean time I've done quite a bit of research on this and feel like I've got enough information without the photos (Though having them would be excellent): Some resources:

1) A youtube video of the exact same repair being done on another (Window) motor using the same brushes:

2) A exploded schematic of the roof components:
http://nissan-europe.epcdata.ru/imgel/Z33/737B_002.png

3) A picture of a 5th Bow motor:
http://www.ebay.com/itm/NISSAN-350Z-...-/151887333921

4) A Nissan TSB for a very similar sounding problem:
http://www.myzroadster.com/Files/tsb.../NTB03-122.pdf

So it seems that my roof has two separate problems that I previously thought were related:

1) When opening the roof "sticks" going in to the compartment, same as this guy:

2) The roof not fully closing as per the TSB

It's currently in an underground carpark as the roof is stuck open - Will pick it up on Thursday and try running through the TSB to get the roof fully closed, then wait for the parts to arrive (Brushes are from the states) and attempt to rebuild the 5th bow motor - Assuming it's successful I'll post a video (If not I'll post a picture of me sobbing holding a bill from Nissan services)

I am having exact same problem as you. This after fixing and replacing the 5th bow motor(which is much stronger and quicker now). I am guessing it might bean alignment problem?????? Anyone know the problem?

Finally found the answer to my problem of the top not closing all the way. Almost closes buy hangs up the last few inches. This guy's video and temp fix acuarately show what I have been experiencing.

The model featured is my 2004 Touring Roadster, Current mileage is about 123k and I have never cleaned this motor or replaced the brushes before, so this is what you can expect if you are doing this for the first time.

Ok, so I've been wanting to do a how to guide for a while and this is a doozie! yup, 5th Bow Motor Repair!! If your 5th bow is getting stuck or not retracting your soft top in the storage compartment, the is a high probability that the brushes in the 5th bow motor are worn out. My how to will show you how to replace these brushes... The brushes can be bought online and they are the same ones used in the tutorial for fixing a sticking window motor, in fact this is pretty much the same as that, only easier!

What you'll need before you start.

1) A couple of hours spare time
2) A right angled (90 degree) phillips head screwdriver (or really short screwdriver)
3) Pair of suitable brushes got mine from Amazon (http://www.amazon.com/MBS5-Stand-Up-.../dp/B001BHLX0W )
4) Small socket set (not 100% needed but useful)
5) Soldering Iron, Flux and Solder
6) Scissors
7) Egg Box and Double Sided Sticky Tape (just messing!)
8) Electrical Contact Cleaner and Rag
9) Fine sand paper (the wives nail file would do!)
10) A couple of band aids just in case!

The whole process took me a couple of hours with help from domrvt (cheers dude!)

Ok first you want to cram yourself inside your Zee (if you are over 6ft I feel for you!) Everything from this point is in picture format so .....


































Once I got the motor back in the car I re-attached the electrical harness and press the button for the roof, and voila! it worked, then put it all back together, now my roof works flawlessly! Hope this How To was of help to those (like me) who were facing a $1000 plus repair job! this only cost me a couple of hours and about $10.

Cheers, feel free to re-post this on any other forums that you know of where people are having the same issue!!!

If you have any questions please message me. This is my first how to, so feedback is welcome.

BlueBadge

PS You will notice that I didn't re-lube the components as I didn't have any grease on hand, but I definitely recommend it! (i'll do mine later!)
Do the pictures still work?
