Does one have to disassemble the motor to put the timing chain slide rail in correct position?
As the plug and pin assembly (about 2.5-3" long) went over the wall, it likely put a shoulder to the warden's belly, which is now wobbling. If just the hub/counterweight/dampener assembly was bent, a replacement can be found. A rather more unfortunate situation will have the nose of the crankshaft bent.

If the lower of the two pins in the slide rail is in position and tight, the upper one (in the plug) can be installed with the chain tension relaxed.
