It should be a smaller diameter bolt than the center bolt. Slightly off center. If the winch is similar to other traditional winches. A picture of your winch would make it easier to help.I have a profile 2000 winch on my shorelander trailer I can't get the center bolt out to pull the gear and replace the strap am I missing something or isn't the bolt supposed to just slide out after removing the nut cause it won't budge
