FS5W71C Rebuild kit ? did anyone tried before?

[Spawn_CA18]

hello there friends. Did anyone tried this repair kit before? it is a complete kit and looks fine to me . but since it is aftermarket i have doubt about quality.

Looks pretty much the same that I've got, but I got mine from another seller on ebay.

I got Nachi bearings in mine, which I think are also OEM for some Japanese manufacturers. Can't really judge the quality, though, I messed up my transmission. End of the above thread^.

did you done this repair to KA transmission or CA transmission? i check the documantation , i think its better to go a little bit detail since i got a original EUDM CA RWD transmission. synchros are not fully interchangeable between KA and CA transmissions as i see

I bought the kit for my CA transmission, knowing the kit itself was prepared for a KA transmission. I didn't see a reason why at very least the bearings wouldn't fit, if anything else would fit, all the better. In the end, everything did fit, only a double synchro was missing. Read the thread, though, I think we did not come to a clear conclusion on CA-KA internal differences, and the CA variants.

But in my opinion, you should only attempt the rebuild yourself, if you know your way around transmissions well, and have good tools, a press, bearing pullers, and all sorts of generic tools, and a set of helping hands. Otherwise I'd just hand them all over to a pro. Or look into adapting a better, stronger, longer, possibly 6-speed box.

it will be my first transmission build. But no problem since i rebuilded the engine by myself i think i can handle the transmission also. FSM will be my holy book in this time


my bearings are worn out . but synchros are fine. friends car's 2nd synchro is totally dead but bearings are fine. İ'm planning to buy a package that includes synchros and bearings , and fix both of them same time .

I have to be %100 sure does the synchros will fit or not .

this is my exact plan

Well, the juice of it is, it probably depends on which version of the CA transmissions you all have (single or double synchros on 2nd/3rd). The comparison and explanations are in the other thread (I don't like duplicate places for information, so I'd rather not quote them here as well). I am in Europe, I had two transmissions, still, I had double synchros on 2nd+3nd in both of them (that would make them "Except Europe" as per FSM).
My $.02: we also thought going by the FSM was a good plan. So, as per FSM, I started to pull off the countershaft drive gear with a bearing puller, nice and slow. It wouldn't budge, but suddenly, a couple of the teeth back faces cracked off flying (you can see the result in the album). This happened with BOTH my transmissions, so I'd advise against the FSM on this specific step. Instead, hammer both shafts out of the bearing plate together, in 1 cm or smaller steps at a time, going back and forth between output shaft and countershaft. Or use a press in a a similar manner, if you have one.
Also, there was a bearing, that was impossible to get off, it would have needed a special, two-faced, flat, bearing remover tool which we didn't have. We ended up hammering off the outer race, and bringing the leftovers to a lathe guy, and turned down the old bearing inner race 0.001mm by 0.001 mm, until it was so thin, that it came off by itself from the shaft. I think this was the input shaft.

So, all in all, I've found it's not even close to the simplicity of an engine rebuild. We can take apart and put together an engine in a day. This took 4 days. Regardless, "I wish you all luck on this great and noble undertaking." (or something like that)

By the time I parts out 2 CA gear box, to select better condition parts to combine into 1 gear box, one of the main shaft gear was cracked a small piece was off, the small piece was off from the gear teeth edge. I have all tools which need for the rebuild, still not a easy job.

Hey Blownhemi
I can't send you a PM somehow!? Maybe because I'm too new here.
I've been wondering for some time about that topic. Do EDM Transmissions have double synchos on the 3rd gear or not. I have some Pics of my opened CA18 Transmission (definitely EDM) and I would like to compare these with your transmission you said you have with the double synchronized 3rd Gear. Do you still have some pictures of your rebuild which I could use for a comparison?
Greetings

You need to have 20 or 50 posts before you can PM, I think.
Look at the other thread linked at the beginning of this one, there's more information there, and you can find the link to my gallery of the rebuild. I'm not sure I have pics from that stage, where you can clearly see from the outside that it's double synchs or not, but of course you're most welcome to look. I know I have pics from the double synchros while completely apart, maybe try to identify from those, if it's the same as yours.

By the way, what is the significance of knowing it beforehand, if you'd like to take it apart anyhow? I'm guessing that's why already you have it open?

Grammar N4zi PS:
There is no such thing with a Nissan as "EDM". Domestic Market means the same country's market as the manufacturers home country. EDM only exists for BMWs, Audis, Renaults, Opels. USDM would be only for Chevys, Dodges. JDM is only for Nissans, Hondas. For Japanese vehicles, there is no USDM or EDM. It's the "European market" or "US market".

Thx mate. I remember now that I have already checked out your pics about a year ago, but I forgot about it in the meantime
From the outside it looks the same as mine. Do you still remember how the double synchros work on that transmission? Is it possible that they are positioned one upon the other, so that I can not see it if its not apart?
I took my transmission apart about a year ago for inspection of the gears. Thats when I made the pictures. I want to know that with the double synchros because if I'm going to rebuild my trany one day, I like to have the parts already ordered before I take everything apart

edit:
I studied your pics again and I think I got it now: The double synchros are indeed one upon the other. So, one clearly can't see it from the outside.

Now, that it's not in your hand anymore, not really. If it were, maybe you could. There are three large and quite deep cutouts on the synchro hubs for the springs. If you shift the synchro sleeve out of the way to the other side (e.g. shift into 1st, on the 1st+2nd synchro sleeve), you may be able to peek down there through the gap, and maybe see, if the ring has more pieces towards the inside. The gap I mean you can see is in pic #24, in the middle left.

[silencium]

Perfect, thx

That's the gap you mean, right?

[blownhemi]

Yes, that's the one I meant.
