Re: Autohelm ST4000 Plus problems
The two halves snap together. No bolts or screws. Use several large screwdrivers a few inches apart and twist the screwdrivers. The two halves should pop apart. If the belt is shreaded, carefully check the pinion gear that drives the belt. The wires inside the belt can cut into the gear and ruin it. Early gears were plastic and often crack.
