Harrison 11" lathe info needed

[roofman]

Any kind person have an exploded diagram of the headstock/main spindle of a Harrison 11" lathe, think they are the same as an L5...any maintenance/dismantling info also as a bonus would be nice.

What do you want to know?

One thing to note, the spindle assembly is balanced. There should be centre punch marks noting which way the main high low gear goes on the spindle.

From what I've worked out, you need to remove the change wheels / gears from the Side of the headstock. There should then be a set of lock rings. You'll need to remove those. Then inside the headstock you'll need to undo the bearing lock nuts.
Undo your silver spindle cap behind the chuck.
I don't think you have to remove the tumbler reverse but I could be wrong.
You will need to remove the shift fork I think.

main spindle has oil leak behind the chuck...L00 nose.

It will probably be a chip or more likely plastic in the labyrinth seal
