How do you freakin put the tranny on the SR?

[Tearlessj]

I've been trying for the last 8 or so hours and just cant seem to get it on. I line up the shaft and try to push it in but it doesnt seem like it wants to go all the way in. I tried reinstalling my clutch but still the same problem. I can get the top 2 bolts in but the bottom isnt anywhere near being close. Any advice? I wanna get my motor in!

[murda-c]

wiggle it.

make sure have the right pilot shaft bushing/bearing(dunno what SRs use)

rotate the shaft the splines might not be hitting.

make sure your clutch is aligned right.

[yoni_nismo]

my gues would be 2 check the pilot bushing and r u using an alignment tool when u install the clutch? good luck i hope this helps

[Sileighty_85]

make sure the throw out bearing sleve is push back all the way on the shaft

[Tearlessj]

Yea I pushed the bearing all the way back. I dont know if it matters but I used a KA24DE clutch alignment tool. Could that be my problem?

[Sileighty_85]

Only if the tool desnt fit through the clutch spline hole

if it fits then no, that not the problem

is the engine out the the chassis?

[kamikazekid]

first, pull the disc out and MAKE SURE IT FITS ON THE INPUT SHAFT! ive seen people try for hours to put a tranny back on and it was the wrong spline pattern. second while the pressure plate is finger tight use the alignment tool and line up the disc with he pilot bushing then tighten down the pressure plate with the alignment tool still in there, wiggle it while tightening so you dont tweak it out of alignment, then when the plate is tightened down take the tool out, and put it back in to make sure its compleatly ligned up. get that tranny up there and try again, also DONT LET THE TRANNY HANG IF IT GOES HALFWAY IN, YOU WILL BEND YOUR INPUT SHAFT, make sure its supported and give it a wiggle to get it in. easier said than done I know, good luck man!

[Tearlessj]

Then that means the tool should be working for my. Its pretty snug when I insert it. The clutch was already on this tranny at one point. I just removed the tranny to put the motor on the stand. So Im sure the clutch is the right one. I also made sure that I torqued everything down tight before removing the tool.

I did let the tranny hang a few times, I hope the shaft isnt bent. It should slide all the way in right? No need to force it in with too much force?

[Sileighty_85]

try this when pushing the tranny on, put it in gear and have some one turn the drive shaft spline end while you wiggle the tranny in

[kamikazekid]

yeah dont force it, they are a pain in the ass from under the car. all i could guess is that the input shaft isnt ligning up with the pilot bushing. try puting the tranny in, grab it from the back and push it forward (hard) and wiggle and twist a bit , if that doesnt work then I would guess the shaft is bent so slightly that its not ligning up at all with the pilot, good luck man ive been there.

[Blown240sx]

Thats the truth. Ive fought them before but the old shaft rotation works wonders lol

[Tearlessj]

Good idea Im ganna go give it a shot and report back. Mind you im doing this while the engine is on the hoist. This is the only way right?

[Sileighty_85]

if you got a spare tire (off the rim) rest the engine on the tire with a little hoist help it'l be easier, but make sure the back of the engine hangs off the tire a bit so you can bolt the tranny up

[Tearlessj]

I just tried to spin the shaft. It would go in half way and get stuck again. The shaft wont spin anymore when its half way in. I cant think of any reason for it to be stuck, besides a bent shaft.

[Sileighty_85]

its gotta go in straight so do the best you can, wiggle it up and down and push

[Blown240sx]

I usually jut draw it in with bolts slowly and evenly. It will get to a point where you can physically push it further on.

[Tearlessj]

I was thinking about that until I read this, maybe I dont have a choice?

I got mine as close and even as I could and then started putting the bolts in. Finger screw them in as far as they will go first and then start wrenching them down across from each other.

Wrench one down a little bit, then wrench the one directly opposite of it. Do that around the bellhousing and it will pull it into place. But make SURE it's as straight as you can get it and that you take your time wrenching them down. Wrench them down like in like 25% intervals.

Do what John Griff said first though, what he said is definitely preferred.

Then Drea240 said this, and the reason why I dont want to try it.

You should never have to use the bolts to "pull" the tranny onto the engine. I can see 2 main problems with this. One, your forcing the input shaft into the pilot without it being properly lined up, this can damage the pilot bushing and cause it to wear prematurely (it's only brass). And two, you can also damage the threads in the block by pulling against the catching spot.

Anytime you have a problem with the re-mount of the tranny, you're clutch/input shaft/pilot bushing alignment is off. Most of the time this happens when you initially push the tranny on and don't have it lined up. You end up wiggling it too much and all it takes is the slightest mis-alignment and you'll never get it on.

All you have to do is pull it the tranny back off, recheck the alignment with the clutch align tool, if that's good then re-mount the tranny only DON'T STOP guiding it on. You should keep ALL the weight of the tranny off the input shaft while guiding it on. And use the tail end to help maneuver the tranny for that last portion. That last inch is the pilot bushing. Also jack up the front of the engine, you should get about 1-2 inches of lift. That will make the alignment much easier. You should get the tranny slid on first try with moderate effort.

Oh yeah I just noticed....WHERE'S YOUR BACKING PLATE? :ughd:

If the tranny has already slid into the clutch and wont spin on the rear of the tranny and you have moved it as far on as you can thats about the only way. Ive done it on many motors and never had issue. Up to you though. I make sure it has slid in the clutch splines though. I dont just force it on.

[SR2Zero]

Are you trying to do this alone? It shouldn't be that hard... Have one person wiggle left to right (person up front) person behind move up and down until you get it.

[Tearlessj]

I have like 3 people helping me. We have tried all the angles possible. I have a spare KA tranny, should I switch the bell housing and try again? The clutch alignment tool goes all the way in. :confused:

[sr20boostn20]

its just gotta find that right spot where it slides in straight.

im usually doing mine form under the car, the first couple times it was a process. 8+ hrs start to finish

i have avid mounts and i need to take the mounts out and drop the motor down to get the right angle to slide tranny on and off,

if i dont touch the mounts it wont go on simple as that

i always do it with the same friend so were pretty good at it now ,

but it always takes the both of us wiggling and twisting to get it on.

ive heard some people say that its easier to get the tranny on upside down the rotate it on the shaft then blot it up

Why would the orientation of the tranny make a difference other than maybe easier to handle?

[Sileighty_85]

he talking about when the engine is in the chassis

cuz of the fire wall its easier to install the tranny by twistin it every which way

[Blown240sx]

ooo I hate putting the tranny on in the car... BLAH :)

[yokotas13]

man
quit being a pussy

try putting a GTR mission on something


Take your time, take breaks
its a PITA but it will go on lol

[DataXUnknown]

It just takes a super wiggle...everyone is telling to to wiggle it in...well, you gotta like wiggle the shit out of it and you can't stop. Spin it a little back and forth, wiggle forward backward. Mine took a lot of wiggling hahaha.

[yokotavia]

the first 2 sentences and the first reply is pretty dam funny. =D


haha sorry, yeah just take your time and its easier if you loosen your motor mounts so they are close to coming off.

[Andrew Bohan]

i had this kind of problem once

turned out kragen gave me the wrong pressure plate :axe:

[holybushoffire]

I had this problem for about 5 minutes, until I took the clutch disc itself and made sure it fit onto the shaft. Which, it didn't at first. I then counted the splines on the disc and the shaft. IIRC it's 27, so I then took some emory cloth to clean up the splines on both parts, just incase of a casting defect. And then, Voila!! it went straight on.

[Roc]

In terms of Paul "Its like delivering a baby to come out and then putting it back on is like trying to put the baby back in where it came from" but more or less just be patient and just man handle it or get a tranny jack if your doing it from under the car.... everything should line up perfectly... if you are sliding it on just right.

[thejapino]

If you look closely at some pilot bushings, one side where the input shaft slides into has a very slight rounded corner. If you install the bushing with the rounded corner into the crankshaft, you'll have alot of trouble getting the tranny on.

When I did my clutch swap, I got this far and wrestled with it for an hour, tired b/c I did the clutch job myself. I called a friend over to help and while I was under the car, I still couldn't get it in. My friend got under there and after 20 mins. he popped it in place. I was through!

[ManoNegra]

Seems like the random wrath of the transmission gods;
I've had some go in on the first try while other's I've battled for hours.
Keep at it, it'll go in eventually.

[Tearlessj]

Its on!!!

After so much time working on this thing, having 3 people help me at a time. Its finnaly in! I woke up this morning planning to call a shop to take over. While walking to get a cup of water I decided to try it ONE more time. I was 99% sure it wouldnt work cause I was doing it by myself. But what do you know, it went on. Ahhh the feeling of accomplishment.

This is what I tried:

I don't know if thats what did it, I am using a used clutch after all. I took the everything apart, cleaned everything up and re greased. Then made sure everything was lined up and BAM!!! It went on. A lot of patience paid off. Thanks eveRyone for the advice!

[Tearlessj]

Now I have another problem, my SR wont line up on the mounts. I always thought they were the same. What can I be doing wrong here?

[DMiller]

if you are talking about ka mounts, you need to swap the side that they are on (left to the right and vice versa)

[sblack13]

what mounts.
KA/SR/CA
S13/S14/S15
motor mounts are the exact same

I always spray wd-40 on the input shaft and the splines of the pressure plate.
Tranny always goes on wayyy easier.

Hmm, so do I have to swap the mounts? I've read both things after searching. Doesn't seem like its going to work without swapping them.

[DMiller]

swap the mounts. report back with success.

[gunmetalr32]

the mounts are same ....

[bo2o]

turn the crank a bit... it will go in...

[sunnys14]

Lube the shaft, it will go in easy ;)

[Sileighty_85]

Yeah Mounts should be the same,
Thay are a bitch thoughyou gotta try and line both of them up at the same time as close as you can then stabb one in the kinda twist the engine and flex the mount to get the other side in.

all the shit on the back of the engine will get in the way you you gotta kinda move that shit around

[chininsan]

Try to tilt the motor back with a emergency jack or something. Or you can just loosen the crossmember and lower it to the end of the studs. This will surely allow you to clear the firewall. Yeah I"ve had to take my tranny off three times in one month and everytime I had to lower the member. It's really not that bad and you don't have to fight the tranny what so ever.

I was reading a post somewhere, I don't remember which forum. The guy had gotten a SR subframe with mount attached and was comparing pictures side by side w/ the KA. The SR driver side mount (LHD) has a slightly different angle then a KA mount, which is why people always complain about their driver side mount being worn out and the passenger one is fine. People run KA mounts on SRs all the time though.

well they they should be both the same Nismo's are for both SR and KA

the reason the Driver side is always F'd up is cuz of the engines rotation from ppl clutch kicking and powershifting causes the engine to pull up on that one

[flip3d]

Lol you need hair to find the hole? :P

[DJ_Sunrise]

Yea.. that shit is a bitch. The tolerances are reaaallly tight for the splines. Make sure you lube that shit with a very thin layer of anti seize. I rubbed some on with a towel. Definetly helps..
