I am trying to put a Muncie 4 speed behind the 327 for the Nomad..I put in a new pilot bearing,lined up the clutch,put the pressure plate & bell housing on ,put the tranny shaft in the hole and the transmission went in but about 1/2 " wouldn't go in.
I thought that I did something wrong so I took it all apart and made sure that everything was lined up,re installed everything and tried again..Still wouldn't go in.
I thought that maybe there was already a pilot bushing in the hole that I didn't see or maybe I had the clutch in backwards..So I pulled everything apart again. Nope..No 2nd bushing and the clutch is installed correctly.
I've taken it apart and put it together 3 times,checked and rechecked everything and I still cant get the transmission to go that last 1/2".Its an aluminum transmission so I don't dare the install the Trans bolts and tighten them up,I'm afraid of breaking an ear off the tranny.
The transmission was installed on a 327 before I got it..What could I be doing wrong??????

Sometimes you have to have someone depress the clutch pedal to allow the transmission to slide into the clutch plate. One other thing, did you slide the clutch plate over the transmission input shaft to remove burrs and "lap" it in?
And doe the throw-out bearing slide on to the input shaft easily.

Push in the clutch.

Try assembling the clutch linkage, and have a helper push in the clutch pedal while you push and shake the trans home. It's worked many times for me, even on front wheel drive transaxles.

Don't pull it inward with the tranny bolts.
 
I had the same problem about two years ago when I installed my BW ST10 and here's what worked for me: I thought everything was lined up just right but like you said it lacked about 3/8 to 1/2 " of mating up with the bellhousing. I used a bright light and focused on the area between the tranny and the bellhousing and could see that the problem was that the front round plate surrounding the input shaft needed to be raised just so slightly. This plate is about 4" in diameter & 1/4" thick and the exact same size as the hole in the bellhousing. I raised the jack about 1/8" and it slid in easily.

Hope this helps!!

Several years ago, I had this same problem. I never heard or thought of depressing the clutch which is a good idea. What I did is loosen the pressure plate bolts slightly taking some of the pressure off but not that much where things readily move or get sloppy. I then tried the tranny again and jiggled it right in. Tightened the bolts and I was good to go. Might have been a coincidence but it worked that one time for me.
 
what are you using to line it all up? a plastic shaft? i used that, would`nt go in, and it would`nt go in. then my buddy brings me a dummy input shaft, loosened it all up, lined it up, using the dummy shaft, FROM a trans, and BANG! it slipped in like was mentioned, DO NOT use the 4 bolts to bring it in.

You guys are the best. I depressed the clutch and the transmission went right in.Thanx to Everyone :congrats::tu
 
I learned something new today. I had never heard about depressing the clutch before.
Yep the real problem is the clutch plate is not exactly centered on the pilot bushing. Thoes plastic alignment gizmos they give ya, don't do a very good job. An old imput shaft is the best. Steppping on the clutch frees the clutch up to allow the trans to center.
 
If you are using the "step on the clutch" method, make sure that you have the transmission in the clutch disc and that you have a firm hold of it. If you are doing it "bench press" style and you're not in far enough, or slip, you have a mess on your hands if you push the clutch in. If you do it wrong, you may get it stuck to where it doesn't want to come out, or you can end up bending/warping the clutch disc.

So make sure everything else is as good as it can be before you step on the clutch.
 
i use another method...where i tighten the clutch up enough so that it still moves a little as i bench press the trans in, or in heavier cases the jack. that's worked like a champ for me for a while. but i have also done the clutch pedal push trick, that requires two people. the plastic input shaft idea works in theory but it ain't nearly as good as the real thing...lol
 
Glad you got it in. The next time you need to do it get an old input shaft from a swap meet. Check the disk and slide it across the input shaft to make sure there are no burrs hanging it up. Install the old input shaft to see if it goes into the flywheel pilot bearing. If not have someone press the clutch pedal until you are able to align it . Release pedal. Get two 6 inch bolts at home deficit and cut the heads of of them. Screw the headless bolts in the two bottom holes of the bellhousing. Get the tranny lower mounting holes aligned on the two bolts. Slide it home. Remove bolts and install mounting bolts. Works for me. Jim
 
Using an old input shaft is the best way to line up the clutch but not everyone has those. I have also seen my budy use his tranmission to line up the clutch without the bell housing on, of course he is 6-7" and can pick-up the side of a house. Snap-on makes a Clutch line-up tool and I believe Lisle makes one too that works better than the "plastic" ones. But is all else fails you can depress the clutch and wiggle the trans to get it to go.
