1991 RT4WD CRX seat pan swap DIY.

I couldn't really find a write up for this so I decided to make one. The RT is a little different than the rest of the wagon family and the seats are a little different too. There are still some pics missing, I will fill those in soon. Without further adieu:

Tool needed:

Socket wrench
12mm socket
14mm socket
19mm socket
Small and medium phillips
Small flat head, or 90* pick tool
Needle nose/regular pliers
Wire cutters
Zip ties
Welder (depending...see below)

Start by taking off the rails from the RT seat.

Next separate the bottom of the seat from the back, here are the bolts you will have removed in total.

20.jpg

Remove the hog clips from the bottom of the seat, I used a Dremel to make it go a lot quicker.

21.jpg

Pull up the seat fabric over the foam, then remove the foam from the seat, it might be sticking so be slow (use it as practice for taking off the CRX foam which you do not want to damage).

22.jpg

23.jpg

Repeat process on CRX seat.

24.jpg

Mount CRX foam to wagon seat, you will find a groove cut into the foam that fits around the pan, match this up then start pulling down the front of the seat cover first, followed by the back. (This is the RT seat foam)

Use zip ties to secure the fabric to the RT seat pan.

26.jpg

Done!

27.jpg

Remove the hog clips from the bottom of the seat back.

28.jpg

Pull the fabric down just a tad and you will notice some rubber cords with C hooks in them. Pull down on the cord and slip the C hook off the seat back spring.

29.jpg

Remove the headrest, pull the fabric up and detach the headrest plastic things by pushing them together at the bottom, inside the seat.

30.jpg

The adjustable headrest thingy has a screw in it, I removed the fabric and foam (gently) and then used a small screw driver to pry out the button. It just slides out. Unscrew the thingy and then remove it like you did on the other side.

31.jpg

32.jpg

To remove the foam off the wagon seat back I cut where the carpet material and foam meet. This made removal much easier. DO NOT do this with the CRX foam.

33.jpg

You will now have a bare RT seat back.

Removal of the CRX seat back foam is almost the same procedure. The headrest is removed by pulling two clips out the front of the seat, just under the plastic thingies that the headrest slides into. Instructions here: http://www.honda-tech.com/showthread.php?t=2478056 There is no adjustment button on the CRX seats.

After looking at the seats I decided to put the CRX back on the RT bottom and noticed two things. 1. They don't meet up flush between bottom and back. 2. The seat is slightly crooked. If you really don't care much, and don't want to weld anything you can leave it as is and enjoy your CRX seats!!

34.jpg

At first I was just going to attach the CRX foam to the RT back, but after looking at the two backs the CRX seems to have larger metal bolsters, and the upper seat nubs. I am therefor going to remove the lower right mounting point from the RT seat back and weld it on the CRX seat back. This will allow proper alignment of the seats as well as retain the CRX seat back support. Pics of that coming soon.

  • I should be getting the seat back welded today and will have finished pics up tonight.
  • Nice write up.
    I thought it was a lot easier, now I think I will leave mine stock.

    I think once it's all in front of you it ends up being pretty easy, if you want to leave the seat back bracket as is. I'll say that the seat felt just fine when sitting in it, and in the car might look totally normal. Sitting on my floor where I could look at it squarely it was just a tiny bit skewed.
  • Thanks for the write-up. I'm wondering if the RT seats could be modified so that the seat backs could be folded forward (like in a HB).... You've seen the seats "naked", any thoughts?
  • Well, when I attached the CRX back to the wagon I used the CRX handle assembly, which is slightly different than the RT assembly. That said, the bolt holes were all the same, and this is the thing that limits how far forward it can move (I'll take some pics of this tonight). My assumption is that if you changed out the handle assembly from a hatch you should get that ability. I will say that the assemblies had the spring coil on opposite sides. The RT had it on the inside, and the CRX had it on the outside. You probably won't be able to use the wagon plastic cover anymore, and I'm not sure how the CRX/Hatch one would work considering you still have to use the lap belt, and losing the plastic means you lose the lap belt holder.

    Me thinks this applys to Auto-belt equiped wagons (USDM)? We Canadians never got that (hated) option. :D

    Optimistic it could work (that, and I'm not too stuck on appearances). Thanks!

    Nice write up! We appreciate the content!

    Added to quick links...

    Damn you!! :lol:

    Tonight I'll take a pic of the assemblies, and how far forward the CRX seat goes in the stock position. My RT seat back is getting hacked atm (to make cutting the bracket easier) and I should have the CRX back ready to go for tonight. After a second look at them I'm actually worried that swapping them isn't going to work as a one for one swap. I think if I have the wagon bracket welded to the CRX seat back at the same distance as it sits from the bottom of the seat it might not work due to the CRX seat back being square on the bottom and the RT being round. We'll see how it works out.

    cool man thanks for taking the time to write it up
  • 1988rt1988rt Senior Wagonist
    hmm looks like i found my next mod
  • emokid11emokid11 Band Wagon
    Nice write up maybe I'll this sometime
  • 1988rt1988rt Senior Wagonist
    man Si seats are kind of rare item
  • Was there any change in ride height or leg room?
  • Difference between CRX (top) and RT (bottom) release assemblies.

    Si seat all the way forward.

  • Welding should be done tomorrow, seems the floor got busy today.

    I'll let you know as soon as they are mounted and take some pics.
  • Well, I learned last night that the RT recline mechanism does not work with the CRX back. This means that I will have to use the CRX mechanism, and I will lose my lap belt holder on the plastics. Small price to pay I think.

    Due to this I need to get some more welding done, and might end up using some shims. I'll have results of the final process with pics up early next week.

    What I did with my Del Sol seats were to drill new holes for the release assembly. After that they sat upright.

    If you notice the RT are angled forward. The Crx/Del Sol are angled back more. Just need to compensate for that misalignment.


    Hope that helps.
  • Well, my main problem is that the metal for the side bolster is hitting the inside facing spring for the RT assembly. The CRX seat frame is square, and the spring is on the outside, and the RT frame is round (see above pics) and the spring is on the inside. After reading your reply I've looked to see if I could drill to overcome this but it doesn't seem possible.
  • vtecn8ivevtecn8ive Senior Wagonist
    Ah yeah I know what you mean.

    I just took a hammer to the metal on the frame. I dented it until it cleared.
    Cleared it and works fine.
  • deckarddeckard Band Wagon
    USDM mod?
    EF Si seats to USDM only auto seat belt equipped civic wagon
    mods if you could please clarify in topic title
    here in Canada, no auto belts
    thanks
  • While this specific swap is being done on an auto-belt seat I'd imagine the seat frames/pans from an RT, regardless of auto/manual belt, would be able to use these instructions as well.

    I have the first seat welded (ended up making a new bracket) and will post up pics this weekend with progress and the finished product.
  • 1988rt1988rt Senior Wagonist
    good luck, I just found some tore up si seats at the local pull-a-part. Looking forward to your next posts to see how yours came out
  • So my friend at work hooked me up and ended up making a bracket that supports the seat back perfectly!

    I was going to put the seat together last night, but then found a set of red/black CRX seats in good shape being sold locally so I'm picking those up on Sunday and should have pics up Sunday night! :mrgreen:
  • So as stated I picked up a pair of red striped CRX seats then had to break them down, remove the covers and reattach them to the better foam from the gray seats. It is kind of a pita but once you remove all the hog clips from the seat covers you see how they all go back on. When you reverse the way you took them off you just use zip ties to re-secure the covers to the foam.

    I plan on doing a step by step of this process in another write up perhaps, but the pics below are the final product. These seat covers came off of different foam, and were all reattached with zip-ties. Can't really tell a difference. :)

    Nice and level. (looks askew due to camera angle...I put a level on it!)

    There are a couple of rub points that are present due to the auto belts. The seats would wear much faster than normal over the life of the car. But Im not too worried about it.

    678.jpg

    I'm going to pull the seat rails and get them repainted since they are now exposed, and I will paint the auto belt covers when I paint the rest of the interior (spring project.) Once I get everything together I will update the main post. After this project I'll continue my interior project by getting the rear seats covered to match...somehow.
  • Awesome write up!
  • Good job, man that looks sick... this is some good work
  • AWSOME RIGHT UP!!!!! YEY! and i have a RT seats on my DX. so this will be awsome! thanks!
  • adamEFwagonadamEFwagon Senior Wagonist
    hell yeah, good DIY.
  • FejFej Wagonist
    Feel like this is a stupid question. But it wasn't exactly clear to me from the instructions if I'd need to use the wagon seatback with crx foam/fabric or just the crx seat back. I'm planning on taking the non-welding route.
