Almost certainly Savage service department can help you. I'm not sure if they can do by phone.
I'll give it a shot--
Can you separate the two halves of the bolt while out of the action? Can you take it apart and put it back together a few times and figure out what is supposed to hold it? Cross pin? interlocking lug? set screw? spring clip?
Does the bolt handle rotation cock the gun?
I found the
Schematic with a blow up of the bolt but doesn't show what I need to see.
The front half of the bolt is not supposed to turn in the action, but he rear half turns with the bolt handle. The drawing calls for three #32 parts they call "extractor spring pins" which really makes no sense. the extractor pin is that band around the front part of the bolt. That band is a spring that hold in the cartridge guide on the left side, the extractor on the right side and the firing pin in the middle. It needs no pins and they show those pins in a different place than what the name implies.
HERE is a video of taking the bolt apart. Your's has come unscrewed.
