on the front pump housing is a large splined stator support, then inside that goes the input shaft. are you talking about the stator support wobbling?
Jamie, the input shaft will come out as you know, the thing I am wondering is why the whole front pump came out. did you have the bell housing off and the bolts were not in it when you picked it up? If you have pulled the whole pump out, there should be some sealing rings on the large inner shaft that fit into a clutch drum similiar to piston rings. These must be snapped together on the ends to go in. Also There is a small thrust washer on the end of the shaft that has tangs that go in some holes to sit flat. Vaseline it on to keep it there, the bad news is that if this is what happened, you have probably pulled the clutch drum off it's matching splines inside, down deep with more washers etc. The whole assy. is going to have to be pulled out and redone for all to go in correctly. Will need to probably put on a new pump to case gasket too. The trick to removing the pump, is to tighten the front band down tight on the drum so the internals won't move when the rings and shaft pull out. To put it back, I use a couple of long studs in the mounting holes to keep the pump lined up in the correct position, then carefully remove them and put on the bell and bolts. Hope I read the thread right and it is the pump that came out.
Shouldn't be cut! Eagle transmission cut my input shaft at the splines and it stripped my stall convertor that they had sold me! Ended up having another shop do the job right cause they don't know crapola! Good luck Jamie, wish I could help.
Did the shaft come all the way out? Flip it over ,but DONOT force it. I would say it is normal.....flipping the shaft from end to end sometimes takes out the wobble which has thrown a scare into you.
Bingo! You're on the same page as I am. I just went and ordered a new pump to case gasket, will be here in the morning. I sit here and looked at it for a minute and it dawned on me that the cast steel part I was talking about is the pump. I don't know a whole heck of alot about transmissions, deepest I've ever gone into one is pulling the valve body out and changeing the shift arm. Guess it's time to learn some more and hope it works when I'm done... I couldn't turn the input shaft on all 3 transmissions I've had in my car, and they work(ed) fine, so I don't know about that.
Sounds Like He's Talking About The Front Pump To Me, But Normally You Have To Use A Slide Hammer To Get One Loose From The Case. But If The Input Shaft Goes In The Middle Of The Part(s) That Are Coming Out Then It Sounds Like The Tranny Pump. Just My Thoughts Though...
Sorry, I didn't realize at first that it was the pump. I thought it was just a front cover or something. Didn't picture the pump looking like that.
I bet you will get it in there just fine but a good tranny book will help too. Public library may have some to look at??? You are also right on the input shaft not turning and the trans still working. Depends on the clearances in the assy and the lubrication that is still clinging to all the parts. Some you have to use a pair of channel-loks to move and others will turn by hand, but still be difficult. If one spins around like a top, sianara to the poor devil, needs a rebuild. Another tip just in case, when looking thru C4 cores, some input shafts will have a straight shank from end to end, and others will have a small undercut section towards the middle. Mostly later models if memory serves me right. Still 26 spline, I try to use the straight shank for high HP purposes, just seems to me would be a stronger shaft??? There is also some shafts that are of a harder material, that are also sought after by racers. The aftermarket hardened one's are not going to give any longer life than a stock one, unless you are running 500 + cubes like the Aussie's are famous for. Been running the stock shaft in mine for 12 years with all sorts of different hp, and have only twisted the splines on one, that was due to other mechanical failures though.
There is one end that has shorter splines than the other, that end goes in the trans. They are normaly 24 spline and the long end is 26 so they can't be reversed. But some are also 26 both ends and can only be used in the trans they came out of. Same for the early c4 with 24 spline in and out, smaller diameter too and must use the 24 spline converter.
