Centec 2C Vertical Head

Does anyone have any details of the internals of the type 2 vertical head for a Centec milling machine – that's the one without the quill feed?

I've just bought one, but have realised that the driven bevel gear on the vertical spindle floats up and down on its keyway. It doesn't have anything to locate it lengthways (vertically), so there is nothing except gravity to resist the separation force of the two bevel gears running together. I'd expect there to be some sort of location collar?

I don't want to run it and discover that I've stripped the teeth!

Thanks as ever in anticipation of some help!

There is likely a drawing on the yahoo centec forum site.

Good evening all,

Just to clear up a piece of misinformation on my part, the driven bevel gear has a threaded nut above it which opposes the lift force otherwise separating the two bevel gears. There is a tangential screw through the side of said nut to lock it in position on its threaded portion of the vertical spindle, and to set the engagement of the two bevel gears.

I didn't discover this until I started taking the spindle apart, as the adjusting nut is out of sight until the top bearing adjusters are removed (and the grease of ages dug out of the way.)

Rgds to all, thanks NDIY for your help, though I haven't found drawings of the internals of the milling heads yet, only the main machine construction.
