Recently dismantled a mantle clock that has not run for 50 years. Made a mental note of where the pallet rack lifting pin was before cleaning and reassembling. At the half hour when the pallet driving wheel goes 'on click' the the rack drops onto the snail and proceeds to strike the hour. Any suggestions please? By the way, I was unable to remove the pallet from the arbor, it was fixed very tight, I did not like to use heat. I suspect the position of the pallet driving wheel and its stop pin is the cause.
