Hi,
Bought an LS3 (525hp) +T56 Magnum combo connect and cruise package. But it wont connect😁
Clutch shaft fits pilot bearing nice and goes all the way in if I dont have the bellhousing in between. With bellhousing it just wont go. Any ideas?
I used the transmission/clutch shaft to center clutch as I didn't have the align tool in hand. I think it should do the job. Been unbolting the clutch 4-5 times and centering it this way every time. It seems that if I put the bellhouse in the transmission does not go in straight?
I used a alignment tool on mine - and no problem. I picked it up online for ~$5.00. If the shaft is hitting the pilot bearing with the bell housing on, either the clutch is off a little or the bell housing is bad. Are you bottoming out like the shaft is too long?
As an aside, I recommend adding a remote bleeder before you put it in - much easier to bleed.
My T56 from an 06 GTO bolted to my LS3 with no issues at all. I have an old input shaft from a Muncie that I use to align clutches. Never has failed me yet. As for the remote bleeder I agree 100 percent. I have a speed bleeder on a long braided line for bleeding it. I can pump the clutch pedal while holding the speed bleeder in my hand. Works great.
Could just be the clutch but to do the job right you want dowel pins in the flywheel aligning the pressure plate (Ahh I see them in the picture, nice!) and an indexing check on the bell housing with a dial indicator to determine that it is really centered. You can get offset dowels for the motor to move the bell housing around a bit and fix anything that is off center.
The plastic alignment tools don't work very well. Usually I use the tool to get close and then push the clutch pedal in and the transmission slides right in, all else being good. That's of course in the car.
You won't want to do this job again from under the car after discovering a vibration. I had a picture around here somewhere about how to do the bell housing indexing but can't find it. I'm sure there's lots of these. I attached my indicator with some very strong magnets to the flywheel
This should be a bolt on package. It says in the instructions that if you're using all these brand new parts bellhousing should be centered and no need for routine measurement.
Measuring if bellhousing is centered sounds like a thing to if alignement tool don't make them mate.
I just dont understand how offset dowel pins can change the position of bellhousing as the bolts are rather tight and remain in the same position.

The crate LS3 will come with big pilot bearing. If you're using T56 bell housing, you'll need the small pilot bearing. Check to see which one you have and replace it with small bearing and you should be good.
i take it there is no access to the 6 pressure plate bolts once trans is installed? the old way was to leave clutch loose and tighten once trans aligned the clutch. you might wanna try a test fit with clutch loose, or maybe without disk even in place to see if it is something else messing with you.

It's not the trans that is the problem it is the bell housing. You have no access to the PP bolts once the bell housing is installed. I don't see even on a GEN1 motor how you have access to the PP bolts once the bell housing is installed.

Com'on Gordon, you're old enough to remember these...
Yes I do remember those form years ago, and yes those would be able to get the PP bolts no problem.
I did mean the Gen1 SB not the LS. With the bellhousing on how would you get to the PP bolts? Unless you "windowed" the bellhousing I don't see it possible to get to them.
Not that this is going to answer any of your questions but this is my setup with a Quick Time Blow shield bellhousing and the large bearing in the LS3 crank shaft.
I also cut the botton flange on the bellhousing for a little more streamlined and ground clearance. Its even with the bottom of theoil pan.
So put the trans in with clutch loose. If it doesnt go, you know there is a clearance issue somewhere, not a disk alignment issue.Put driveshaft yoke in and see if it spins. Then gently remove trans and bell hsng and tighten clutch.
