I'm rebuilding my trailer door. I have a Bargman L 100 door handle and it's sticky. Has anyone rebuilt/cleaned one of these without purchasing the $150 rebuild kit? I'm wondering if I can just stick the entire thing in an ultrasonic cleaner or if it's better to just disassemble it and clean it up as best as I can.
I don't think it will harm anything to soak the whole assembly in some sort of cleaner or penetrating oil. There should not be any internal components that will be chemically damaged. However be warned to drain it for a long while before reassembling it in the door. I did my L66 with penetrating oil (Sprayed in generously, not soaked) and wiped it down before putting it back in the door, and it drooled oil down the outside of the door for 3 days. I've also found in some instances that the crud that accumulates hardens to the point that some of the internal parts will not clear of it without a little gentle persuasion. Metal shavings and other debris may need to be removed with a brush or pick. But it can't hurt to try the soak method first, then get inside it in more depth if it is required.
