Hey guys just got my tci converter today 26 spline input and when I went to drop it in the trans the input shaft won't sink. I pulled out the input shaft which is a brand new hardend shaft from PA and the splines match up but the input shaft won't slide in? I checked for burs on the shaft and couldn't find any guys have any ideas? Maybe a slight defect in the shaft? Thanks

Sometimes they are harder to get in than stock stuff. But I will say, talk to the guys ya got it from before you try to force it in.

Do you have the old shaft? 1970 had a 26 spline on both ends and had a differant forward drum. The 24 spline trannys are smaller in diameter so it would be sloppy in the bushing and easy to catch. I would measure diameter of the splines since the are machined down some.

Friend of mine had same exact problem with C-4 for his Ranger sent it back and second one fit no problems, it was also from PA.

been in that boat before! i dont know the brand i got,got it from ptc,but it was that way too.the splines were'nt deep enough.shoulda sent it back but didnt have time so i cut them with the thinest cutoff wheele i could find.dumb assed i know but it has been worken for over 200 passes.

Thanks guys for the replys, I talked to PA and TCI they both said to use a mallet and hit it in sometimes they are a real tight fit, I did that but I could only get it 1/8" in the spines on the input shaft aren't tapered enough , I will send the shaft back to PA for a new one I just hope it didn't screw up the onverter at all! I thought about using a small grinding wheel to taper the spines but figured the hardened shaft would be a PITA to cut. I don't have a stock one but I will let u guys know when I make some progress , maybe this might be a common issue with aftermarket hardened shafts,

WE talked to the guy on the phoone who makes them shafts are they said they dont ever have issues with them

Of course they would say that.

does PA manufacture the shafts? or is it another company? i saw that TCI sells hardened shafts too wonder if they are the same as PA

 

[bigblok86ranger]

Maybe I know TCI sources some parts from Sonnax and I am sure PA outsources parts too. It costs 100's of thousands of dollars to do tooling so it is easier to outsource them from companies that already have the tooling. Example; my TCI billet R-code racing servo was sourced from Sonnax, they have a clearance issue that is common knowledge but TCI says they have never heard of it.

hey guys i got a new input shaft from PA yesterday and it fits perfect no hammers or black magic to make it fit. guys at PA are good to deal with.
