Trick to installing converter on shaft?

[grdprx]

I'm having issues I think. I tried for an hour this morning to set the torque converter, but it's about 1/4 inch outside the trans case. Looks like it needs to be about 1/2 inside to bolt up properly to the flex plate. I got a flashlight to check the position of the transmission pump, heck I even stood the tranny up on the tail shaft hoping gravity would do the job!  Arg    I didn't think it was this hard.

Re-check the position of the transmission pump and keep trying.  It's a pain

[Chryco Psycho]

just bump it in & out about 1/4" & keep rotating it as you bump it , you will find the right spot

No trick, just patience. What Chryco said.

I'll give it another go. Thanks

Just a reminder,

Make sure you put oil in it

I did, thanks bud.

Do not put oil in it. It takes Trans fluid

It can be a major b***h. I tried this on a FWD car but I would assume it works for RWD too:
Jack the car up and place on jack-stands. Put it in gear and have a buddy turn the back wheels while you work the convertor in and out. This takes the rotating of the convertor out of your job. Also, find something to go over the studs on the convertor that will help you get a hold of it. I used angle iron.

Previously I had tried doing the rotating and pushing in/out all by myself but after several hours I hadn't gotten anywhere. Tried that trick and got it in 5 minutes.

Im pretty sure he knows i was referring to transmission oil/fluid

.................Here's the trick.................with a small screw driver turn the pump lugs to the 6 and 12 o'clock positions.........kim............

[grdprx]

Yes, tranny fluid is the oil I used. So I'm taking another crack at it. I've been lining up the pump, I put a little trans lube on it to see if that's help slicken things up. Well, all that showed me is that I'm not engaging the outer spline. The lube hasn't been disturbed. What a PITA.

Just swap in a  4-speed....     problem solved

[375instroke]

I just spin it and push it up and in.  Never had a problem.

Oh my, those splines on the input shaft would be a PITA then....

[Rolling_Thunder]

Put the 4-speed trans in gear, use your nifty spare driveshaft yoke and turn the output shaft / turning the input shaft thusly for it to align with the clutch disc splines....     I've never had to do that...    I usually just manhandle it and yell, cuss, and talk dirty to it...    then it usually slides right in.  

[375instroke]

How does the input shaft turn from the output shaft if there is no pressure to apply the clutches or bands?

I was referring to a 4-speed -- sorry about the confusion  (edited above)

[John_Kunkel]

As an absolute last ditch technique, turn the trans straight up resting on its tailshaft and drop the converter in using a couple of long bolts in the drive lugs...turn slowly the converter while alternately raising and lowering it until it falls all the way in.

Don't do what I did! I climbed in the engine bay set the convertor on the shaft, spun the convertor while pushing in and slammed the convertor in so hard I cracked the tabs. I unknowingly went on to install the engine do all finishing procedures. On my first test drive got about a mile before they let loose and left me stranded on the side of a 6 lane highway during rush hour. Be careful! 

[grdprx]

I discovered why I'm having so much trouble. The outer gear in the converter is not beveled like in the stock converter I took off!  I also checked the inside diameter with 1/2" sockets, just for comparison. I can fit a 15/16 in both converters with a little wiggle room. A 1" socket does not fit either, so I guess I'm going to just have to get lucky with this thing.

Make sure you have the correct torque converter spline count...Early 727's(1965-early 1966) had a different spline count than the later ones.

[wrench]

yea, somethings wrong. they can be tricky to install but not that much. wrong converter or ??

[grdprx]

Good idea, I just checked; there are 27 splines on both the converter and trans..  Thanks

Has anyone has experience with Dynamic torque converters?  Maybe they screwed up, not having the bevel in there for the outer spline.

[grdprx]

Well, I called Dynamic converters today. They said to stand the trans up in a 35 gallon drum, try and install that way.

[oldkimmer]

................I had this happen last fall........the converter hub was too big to slide into the pump bushing ..........measure the hub to see if its within tolerance.....1st 1 in 30 years....kim.........

OK, I counted the outer splines previously, the smaller shaft has 19 splines.     Looking at the case, there is a big 65 with some other numbers on the bell housing and tail housing.  Looks like I've got a Early 727.

I saw mention somewhere on here about converting it to a 24 spline?  How do you do that?

[John_Kunkel]

To convert a '62-'66 19-spline to 24-spline you need to replace both the input shaft and reaction shaft support with parts from a '67-'77.
