Hey everybody,
Well my long search for an automatic has not turned anything up as of yet. ( For those who remember I'm looking for a 727 short shaft to sit behind my 383 4x4.. ) ya I'm still looking.
As I wait I now need to replace the input shaft and bearing ( a royal pain in my &$@.. ) I might add... on my 435.
So question one; Has anybody replaced am input shaft?
question two: Do I need a press? Is it easy?
I know when I put the last input shaft bearing in the hole. The crank's hole wasn't the right size. (that leads me to believe the crank might have been from an auto and somebody machined it)
So the bearing had to be turned down 2 thousanths. And being the idiot that I am I didn't replace the shaft when I should have. So ya chatter chatter chatter.. It's of course gotten worse.
Ya
Any help would be great!
input shafted !!!

Pulling the input shaft on the 435 shouldn't be hard,
just remove the bearing retainer, then you have to
rotate the input shaft so that the "flat section" of
the gear on the back of it is up, and it should slide
right out. Bearing should slide right out with it.
Did you try to FREEZE that input shaft bushing before
you installed it? I've had ones that seemed to be
just a hair too big, but if you freeze metal it contracts,
and then they are much easier to coax in.....
Same principle works if you ever change out a
flywheel ring, first time I tried that I pounded and
pounded with a hammer with no luck at all... then a
friend told me to stick the flywheel in the freezer,
and the ring in the OVEN... and.... they slid
together like a knife through hot butter!

Thanks.. sounds like it will be a piece of cake.. I'm doing this in the driveway.. It's over a hundred degree's here still.. Plus I'll need to rent a engine hoist // floor jack.. then once it's out I'll need to measure it and order it. I hope that's all that's wrong.
About the freezing I didn't the last time, come to think of it it was over a 100º when I did the swap last year..
Freezing metal to shrink it is logical.. I'll do that this time. Keeping my fingers crossed.
How easy should the shaft slide back in? I know it should be snug but snug to the point I'll need a big arse pry bar - 2x4's ?
thanks for the reply..
