I need to replace the bearings in my 1986 Hunter Legend 40 traveller cars. I have owned the boat for 3 years. There is not enough room to slide the cars off the end of the track. There is no access to the space underneath the track to see what the screws in the track screw into. The track and the cars are Rutgerson. Does anyone know how the track is attached to the boat? I am afraid that if there are single nuts, as I remove the screws they will fall away, and I will have no way to retrieve them. Is there a way to disassemble the cars without having to remove the track? There are 2 small phillips head screws on the ends of each of the cars.
