Those Relays are very Touchy. Note in picture above the core inside the coil. One type has an angle on the side by Armature. The other type is straight. (no angle by the Armature). Not sure without looking which is which, but one type is a Latch (Set-Reset) and the other is pull-in and drop. The Set-Reset Armature MUST touch the core to latch. On the Pull-in and drop the Armature MUST NOT touch the core. Set the core properly then use a contact bender to adjust wipe moving the STATIONARY with the bender. Usually Hall Calls and Car Calls are Set-Reset to look at if in doubt which core type is which.
