Title: Harley Yokes and headstock. A Question
Post by: klogan45 on December 16, 2007, 03:42:22 PM
I've managed to get a set of harley youkes and headstock, without the headstock tube. Much better than the yokes on the trike that I'm building!!!
Can anyone tell me if I can remove the headstock from the bottom yoke? If so how?
 What I would like to do is replace the headstock with a new one the same length and diameter as the headstock that is on the trike now. I know that I will need to have it made, but know someone that can do the job, don't I Doc (TP). ;)
The idea being that it will be less hassle than cutting out the existing headstock tube and fitting a new one.
Thanks guys, I'll appreciate any help with this.
Regards
K

By headstock I presume you mean the steering stem?
They're usually a tight interference fit & are pressed in with a hyrdaulic press. Some will have grub screws somewhere, through the side of the yoke into the stem. You could either press the old stem back out, (your local car repair garage should have a hydraulic press), or you could drill out the bulk of the stem from underneath, leaving a thin wall round the edge & collapse it in on itself to leave a clean circular hole.

Hello Mankster i've had a good look at the steering stem. I've attached a couple of pics.
There is a bolt at the bottom of the steering stem and a circlip, and a cut out in the side.  Does this mean that its not pressed in but screwed in?
Thanks again

Most aftermarket "slab" yokes have a bolt top & bottom -my own trike ones have. That'd be enough to hold 'em once the yokes are clamped to the fork tubes but you could add the grub screws for extra peace of mind if you like. Although your stem's held by the screw it's probably still a tight press fit.
The cut out in the side looks like a steering lock -the lock barrel would be in the side of the headstock & turning the key would locate a pin into the slot so you can't turn the forks. Not sure why it's that shape though. I've seen self cancelling indicators that work off a spring loaded pin moving over cut outs in the stem.
