Less than two years out the plastic caps on my jack motors were disintegrating. After a year I can see the replacements are doing the same. I imagine the UV light is doing the damage. They start sloughing powdery residue, the center of the caps start separating and if you try to remove a cap it'll crumble apart.
My unit is stored outdoors but I'd think the caps would last longer than a couple of years. If these did have to be removed to operate the jacks manually they would surely come apart and have to be replaced.
I'm thinking of trying to cover them some way to protect from the UV rays. Maybe coverring them with a same size circle of 3M tape.
Have any of you had this issue and what have you done to protect the caps?
