Hi, just servicing my first 2824 date only. All seemed ok, good amplitude, winding and date setting ok. But when I try and set the hands it’s pushing power through the train causing the escape wheel to skip passed the pallets. Any ideas? Thank you.

If it's good amplitude the pallet pivots should be OK. 

I've had this when one of the pallet jewels is loose. Worth checking.

Do you have a pic of the pallet/escape wheel?

 If you are sure this indeed is whats happening,  two issues must be at work simultaneously, 

First;  too much  torque must get to the train ( due to real tight canon pinion).

Second;  pallets must let the escape teeth slip ( due to loose pallets, excessive side shakes on fork or escape wheel due to  bent fork or escape pivot, or worn out jewel hole)  so  each one named must be checked.

Video just shows its happening, doesn't actually show the cause.

Thanks for the replies on this, and they were spot on for how I described the issue. I found the issue, the minute train bridge wasn’t screwed down enough, leading to wheel(s) jumping during handset. What I was seeing on the pallets was just the backlash during the wheel bouncing the escape wheel…no actual slipping passed the pallets.
