Automatic Works Oiling

[DJT2]

Hi guys I'd really like some advice. After rebuilding a zodiac movement. The watch winds perfectly, however after installing the automatic works it becomes harder to wind. It does wind however it's really stiff. I'm about to soak the reverse wheels in lighter fluid, once clean I'm wondering if I oil them & if so with what

Was it hard to wind before?

It was but really stiff, the movement was just filthy & mainspring was snapped. I've just resolved the issue, after a 4hr soak in lighter fluid & another hour in isopropanol the reverse gears seemed looser. After which I've reinstalled & used D5 on the post & between the gears. Now it winds like butter.

in that scenario i would build the automatic framework bit by bit adding one part at a time and then testing the winding, keep on going until it becomes stiff again. 

 

This way checks each component is functioning correctly until you find the part thats making it stiff.  One thing to ALWAYS remember when reassembling is that if a screw is not to long in that it interferes with other parts below the bridge.

 

i.e. if its stiff with just the bridge on its own then i would check what the bridge screws are interfering with.

 

Good luck and let us know how you get on.

I think that no grease should be put on wheels or pinion teeth. Seiko magic lever being an exception.

Once the wheels where reinstalled I added D5 to the post & then a tiny drop of D5 on the top of the wheel where the wheels join. I've pointed out where I oiled in the pic

That is the best way to fault finding.
