I've never been happy about the effort it takes to close and latch the common Trimark 60-650 lock assembly on our primary coach door. Knowing that the bolt on these locks are subject to stress breakage, making it quite difficult to get the door open for repairs, I decided to remove the inside panel and make sure everything was well lubed to minimize friction. With the panel off, I realized there are two springs used to close the bolt, one that's tucked away inside the bolt housing, and another that is primarily used to return the pull paddles to their resting position after the door is opened or closed. I found the spring return for the paddles is quite stiff, and that removing it allowed the door to close and latch with not much more pressure than that needed by most conventional residential doors. The downside of course, was that the paddles flopped around a bit without the return spring to hold them retracted. A brief search of my on hand spare springs turned up a much lighter spring of the correct dimensions to use as a replacement for the heavier OEM spring. The door now operates much easier, and closes with minimal effort while still retracting the paddles. My wife is also very pleased with the mod, and that makes me happy too!
