Here's a little tranny how-to for j00!! (34 pix)
Well I had a mishap with my newly installed clutch. The splines on the clutch disc completely stripped out and took a little of the splines off the mainshaft in my tranny. Not cool. I did not want to install the new disc with the manishaft partially stripped so I bought a new mainshaft from Acura, $230. I figured that while I was in the tranny I would do a little how-to. A lot of people are afraid to go inside a tranny for fear all the parts inside, I guess. This is my attempt at show-and-tell. Btw, this is on a ‘92 GSR YS1 cable transmission.
First thing first, disconnect the battery and put Nikki in the house https://honda-tech.com/forums/images...s/emsmilep.gif Here are the tools that I used. http://images.snapfish.com/3388%3A73...888%3B49ot1lsi A shot of the patient and its new inard part http://images.snapfish.com/3388%3A73...888%3B48ot1lsi The first thing that I did was remove the clutch lever and release bearing by removing this bolt right herrr http://images.snapfish.com/3388%3A73...888%3B46ot1lsi then I removed the back up light switch http://images.snapfish.com/3388%3A73...888%3B44ot1lsi remove clutch cable bracket http://images.snapfish.com/3388%3A73...888%3B43ot1lsi then remove a few other misc bolts around the case http://images.snapfish.com/3388%3A73...8%3B3%3Aot1lsi http://images.snapfish.com/3388%3A73...888%3B39ot1lsi then this sealing bolt http://images.snapfish.com/3388%3A73...888%3B37ot1lsi which reveals the dreaded snap ring http://images.snapfish.com/3388%3A73...888%3B36ot1lsi lastly remove all the bolts that hold the transmission housing to the clutch housing http://images.snapfish.com/3388%3A73...888%3B33ot1lsi http://images.snapfish.com/3388%3A73...3A%3C%3Aot1lsi this is a good point for a drink of water http://images.snapfish.com/3388%3A73...8%3A%3C7ot1lsi ok, now crack the two halfs apart http://images.snapfish.com/3388%3A73...8%3A%3C5ot1lsi using the reverse snap ring tool (a must) spread the snap ring and the countershaft should clunk as it drops off the snap ring http://images.snapfish.com/3388%3A73...8%3A%3C3ot1lsi closer look http://images.snapfish.com/3388%3A73...8864%3C2ot1lsi and pull the trans housing up, you may have to wiggle it a little, and there you have it…the inards are exposed http://images.snapfish.com/3388%3A73...8864%3B7ot1lsi then start removing the pieces around the counter and mainshafts, first the reverse changer holder http://images.snapfish.com/3388%3A73...8864%3B6ot1lsi then the reverse idler gear http://images.snapfish.com/3388%3A73...8864%3B2ot1lsi then the shift piece/shift arm holder/select arm……stuff http://images.snapfish.com/3388%3A73...8864%3A9ot1lsi http://images.snapfish.com/3388%3A73...8864%3A6ot1lsi now remove the countershaft w/ gears and synchros, mainshaft w/ gears and synchros and shifter forks all at once http://images.snapfish.com/3388%3A73...8864%3A3ot1lsi http://images.snapfish.com/3388%3A73...88649%3Bot1lsi and there sits the whole clump http://images.snapfish.com/3388%3A73...55886498ot1lsi another good point for a drink of water http://images.snapfish.com/3388%3A73...55886495ot1lsi here is the new and old mainshafts together. Also I have removed all the gears and synchros off the old shaft and have placed them upside down, in order, off to the side http://images.snapfish.com/3388%3A73...55886488ot1lsi here is the old mainshaft, you can see the shininess, that is where is has a little wear from the clutch disc strpping out http://images.snapfish.com/3388%3A73...88647%3Bot1lsi now, grease the new mainshaft up with assembly lube and start putting the gears and synchros on http://images.snapfish.com/3388%3A73...46795565nu0mrj http://images.snapfish.com/3388%3A73...46795559nu0mrj here is the final assembled mainshaft http://images.snapfish.com/3388%3A73...46795555nu0mrj clean the hondabond off, wipe some old grease off, and lube up the sockets where the counter and mainshafts and shifter fork go into the tranny http://images.snapfish.com/3388%3A73...46795549nu0mrj now put in the countershaft w/ gears and synchros, mainshaft w/ gears and synchros and shifter forks all at once http://images.snapfish.com/3388%3A73...46795543nu0mrj here is the tranny with all the inards in and lubed up ready for the tranny case to go back on http://images.snapfish.com/3388%3A73...55886449ot1lsi http://images.snapfish.com/3388%3A73...55886443ot1lsi now, if you get something out of order the helms manual, which I know you bought before you attempted this, has a nice exploded view with descriptions for everything inside and out of the tranny http://images.snapfish.com/3388%3A73...55886439ot1lsi Just put it back together in reverse order and don’t forget Hondabond and to torque all the bolts down correctly. If something is hard to put back together, then that probably means something is not right so double check. I hope now that you realize that working on the transmission is not all that bad. I may have forgot something so take your time. Overall, it took me about an hour, and I was farting around. Level of difficulty would be about 2.5 on a scale of 10, at least I think so. https://honda-tech.com/forums/images/smilies/emwink.gif https://honda-tech.com/forums/images...es/emsmile.gif |
good job. I like the portion when you had a drink of water. we did one of these last week and it took us about an hour with afew drinks from the hostess.

Snap ring pliars are not needed. Needle nose pliars will get the job done.
That white grease is not needed, MTF is.

Did you clean, inspect and check the clearances before you put it back together? Usually when I see a mainshaft torn up like that there are usually syncros getting on the loose side and/or bent shift forks. |
Re: Here's a little tranny how-to for j00!! (Jeff C)
Excellent job.
Good clear pics! Ive got a question or two if you don't mind. 1 - Think you can point out for me the bearings that give the dreadful "whine" on my old '91 Si tranny? (I want to attempt the rebuild, but don't want the tranny sitting apart while I wait on the bearings. I want the parts on hand so I can get it back together the same day so I don't forget how things go. Letting it sit on a bench for a few days can only lead to possible problems) 2 - And I assume those bearings on the shafts slip off, no press needed? 3 - And the bearings that remain in the case, are they easily replaceable, or a press is necessary? |

Re: Here's a little tranny how-to for j00!! (EGStreetHtch)
bloody excellent mate!
real good work, i assume it would be that easy to change a syncro too? |

Thanks for the helpful post!

Re: Here's a little tranny how-to for j00!! (Chiovnidca)
PhatOptimo, you can use your pliers and drink your https://honda-tech.com/forums/images/smilies/embeer.gif, but i wouldn't trade these snap ring pliers for anything. https://honda-tech.com/forums/images...s/emsmilep.gif
Chiovnidca, about 75% of the gears and synchros in there were replace 25k mi ago. There is no play. The problem was the splines on the outside end got a little beat up. The inside are ok. 7PSI CRX, I personally am not familiar with the whining that you are talking about so I cant help you there. Correct, you do not need a press. However, there is a nut on the end of the countershaft, like the axle nut, that is a little PITA. The bearing in the case can easily be tapped out with a mallet. tinkerbell, yes it easy to replace the synchros. you just need to make sure that you get them back in the correct place cause they are not all exactly the same. Mista, I am glad you told me about those things awhile back. They are awesome!! https://honda-tech.com/forums/images/smilies/emthup.gif Thanks for the props. I hope that it helps somebody. Now I have to go install the tranny back into the car. https://honda-tech.com/forums/images...es/emsmile.gif |

Re: Here's a little tranny how-to for j00!! (slashDEVslashNULL)
ok, not as hard as its cracked up to be...
is putting in a LS 5th gear just as easy? |
Re: Here's a little tranny how-to for j00!! (SilverCIVIC96)
I am not sure what all is involved in putting a different gear in, ie having to use a different synchro too, but replacing gears is yes, just as easy.
|
Re: Here's a little tranny how-to for j00!! (SilverCIVIC96)
once you get the gear shafts out, swapping fifth gear only takes about 5-10 minutes. Getting to 30mm nut off is the hardest part.

Re: Here's a little tranny how-to for j00!! (Mista Bone)
Mista, thanks for the input. I know how to replace a stock gear with a stock gear, but i was not for sure what would be involved in replacing a stock gear from one tranny with a stock gear from another. https://honda-tech.com/forums/images/smilies/emthup.gif
slashDEVslashNULL, i have done a couple to those too. You would take the tranny apart the same way (obviously) and remove the gear sets the same way (obviously). The diff just pulls right out. The biggest PITA about a Quaiffe install is getting the correct shim. How I did it was put the put the Quaiffe in, reassemble the whole tranny and check for shim clearences just like the manual said. If it was good, then remove the case and apply the HOndabond. If it is not, keep trying different shims till you find the correct one with the proper clearences. PhatOptimo, yes its a teg tranny, YS1. And yes the tool comes in very handy. Thanks for adding the pics too. https://honda-tech.com/forums/images/smilies/emthup.gif |
Re: Here's a little tranny how-to for j00!! (Jeff C)
good write up! I agree that Trannies aren't anything hard to work on.. just gotta remeber where shit goes!
|
Re: Here's a little tranny how-to for j00!! (Jeff C)
those winey gears could be on either side of the diff - mine were, but you will need a puller to get them off. the whine could also be the bearing on the shaft or the ones pressed into the casing. the ones in the casing you can just pop out too.

Re: Here's a little tranny how-to for j00!! (Burke)
Jeff;
That's a great write-up!! I totally agree with the "water" aspect of it! (no preaching, just a little fun) Maybe I'm in the wrong generation, but what's a "Nikki"? About that snap ring; Can the snap ring be removed / or installed through the access hole? The access hole doesn't look large enough to get it in and out. You made a comment that you will hear a "clunk" when the countershaft falls free. Am I correct that this is due to already having the cases spread apart? If you just pulled the cases apart, I'm assuming that the gears would fall all over the place as they came off the counter shaft. When putting it back together, do you have to worry about the countershaft being in the correct position to get the snap ring on? Does the snap ring just flop around free, after bolting the transmission halfs together and before it's snapped into place? Thanks!! Wes Vann |
Re: Here's a little tranny how-to for j00!! (Wes V)
I also have the same question as listed above...
In addition to that, I'm also wondering about the 'whine' that my '90 Si (CRX) tranny makes. Someone said that it could be the bearings in the differential??? And you need a puller to get to those? What's a puller? |
