Rear diff pinion shaft not moving (1 Viewer)

[TexYoung]

ok, what seems to me to be a dumb question. I am replacing the rear axle seals on my 73 40. I removed the pinion shaft pin and expected the shaft to come right out. Ok, I am a Chevy guy so bear with me. The shaft is not moving, even lightly tapped it from the topside with a hammer and no go. It appears to be stuck to the top pinion gear. Some trick to it or something I am missing?

Are you sure the whole pin came out?

Picture of the pin would be helpful. Have to be sure the complete pin came out.

Beat me to it.

I am pretty sure the entire pin came out. The shaft rotates freely with the pinion gear when you rotate the axles.

Does that look like the entire pin?

the bolt looks short and the end is mushroomed.

you can hold it up to the carrier and see if it would go into the pin, my guess is no.

you will most likely need to get a bigger persuader to get it out

The shaft rotates with the pinion gear when you move the axles. It appears to be stuck to the top one. If I beat on the shaft am I going to damage that pinion gear or any of the other gears?

I held it up to where it threads into and I looks long enough. I'm afraid if I beat on that shaft I'm going to mess up by gears

Have you removed the C clips for each axle?

As I remember that pin gets narrow and goes into the other side of the carrier. At another location have loose diffs to grab a pin. C clips will not come out until pinion shaft and block is removed so inner axle shaft can slid in enough to clear the side gears.

Anyone have a length measurement on an unbroken bolt he can compare with?

Isn't the bolt end normally rounded?

 

[TexYoung]

The bolt is definitely too short. Since it goes through to the other side of carrier so part of the bolt is still in the shaft and going into other side. Suggestions for getting it out?

if you are saying the pin is rotating in the carrier along with the spider, you already have damage, question is how much.
with the pin rotating it doesn't matter that the bolt is broke and a piece is left in the pin as it is rotating, nothing is keeping it from rotating.
only thing holding it now is wear or if the broken piece has some friction in the hole
you need to just drive it out, you're not going to damage it more than it is already,
if the holes are worn enough from the spinning pin, you may need a new carrier

Turns out the shaft was frozen to one of the pinion gears, I had to beat it with a mallet back and forth for about an hour to get it out.. Once I got it out you could see where the remainder of the bolt was inside the shaft, there was no portion of the bolt in the carrier on the other side, as it did not go all the way through the shaft. Obviously I was not the first one that had been in this diff. Fortunately I have a friend that has a good used third member for me. I will pick up and install tomorrow. Thanks for all your help.

Lot of work to change two seals. Ugh LOL!
