Just wanted to ask if there's a special trick to removing the birfield off of the axle shaft?

I believe Chris has popped a shaft at the splined end. We have several axles lying around with broken birfields. Figured it'd be easy to swap out the shafts & keep the good birfield with rings. Haven't torn it apart yet, wanted to ask the ?? before I go get dirty.

Pre-shate it,
Brad.

They are a bear to get apart.I tried the method that works
on Toyota shafts but it didn't work for me on the Samurai
parts.That method is to place the inner shaft end of the
Birfield assembly into a thick steel tube and then slam
the whole menagerie down onto a hard surface.Inertia is
supposed to cause the pieces to seperate.
Fearing that I might cause a stress crack I didn't want
to get too crazy beating on the Birfield.I ended up
building a puller to get mine apart.

Did you add any heat to the birfield first?
I'll give this a try & see what I can come up with.

Do you have any pics. of the puller you made? If I can get this to work I'll go ahead & seperate all of the broken ones.

Thanx,
Brad.

Heating the Birfield won't help.There's a wire ring on the
shaft that holds it in the inner race of the Birf.On the
shaft assemblies I've seperated the ring gets sheared and
several spline teeth get knocked off the end of the shaft!
Apparently these things were not meant to come apart. Sorry,
no pictures of the puller.I haven't got a digcam.It works like a
split bearing puller.Two halves surround the raised seal surface
on the shaft and bolt together.Four screws going through the
puller then push the race off the shaft.It's made out of heat treated alloy steel.
I know this info is useless since most people don't have
a machine shop at their disposal to make one of these.
Someone out there must have a more "shade tree" method of
of disassembling Samurai Birfields.

Everyone that's switching to the cromo shafts have to seperate them. I may try to call Calmini or Brent at TT & ask if they have a suggestion.
Thanks for your help rollerskate.

Brad.

i have always poped them off the way that rolerskate has with the tube and slam method and never had a problem...

I must have had a couple of toughys.I pile drived them so
hard that I mushroomed a piece of 1/4" wall DOM tube,and
the Birf still wouldn't seperate.

Hey Scott, I just got a set of Longs for my Yota axles, how do I put them on my inners? I will search the Toyota board unless you can drop me any info.
Thanks
