Se5 4HA half shafts needed

Post by Stupopt1 » Wed Jan 03, 2018 8:31 am

Hi all,
I need 2 new (2nd hand) good condition half shafts for a 4HA rear axle for my Se5.
preferably with hubs , but also preferably with the hubs removed.
I am refubing my axle and the threads on the half shafts have been squashed at some point, and or cross threaded, pretty badly so are not useable.
Unless anyone knows of a place that can refurb the threads ?

Any help is much appreciated.

Stuart

Don't think it works with external threads?

a photo would be helpful to see if the thread is salvageable.
otherwise it Should be possible for someone with a lathe to part off the damaged thread and drill and tap the end of the shaft for a reduced diameter stud?
Its how I deal with snapped off threads on large hydraulic puller bars which are case hardened.

I'll get some photos up later.
do you think I'd be able to drill and tap the end of the shaft, is it not hardened ?

I think I might try getting them welded up then the thread re-cut on them, anyone tried this ?

I wouldn't bother, from the meat left you can carefully clean up the existing thread with a die or die nut and fit new nuts. Granted, they look 'orrible but don't look at 'em until you've done the above.

I'd agree with a good clean up with a rethreading file before running a dienut over it. Not sure of the thread form. Don't be tempted to use a triangular unless you can be sure of the thread form being 60.
Then I would assemble everything. Backplate, bearing retainer and gaskets etc and take it to a press. Have the hub pressed on. Apply some Loctite 660 to the superclean thread and nut and torque up to about half the book value. Fit your split pin and put on axle.

Worked fine for me.
