Jumping out of 2nd
Posted: Fri Mar 22, 2019 5:34 pm
My Dart jumps out of 2nd occasionally, usually on the overrun. I have taken the top off the box and tried to set up the selector rod detent springs as described in the workshop manual but can't get anywhere near the loads quoted.
My box had no shims between the plugs and the springs but the plugs were screwed well down the holes. Unfortunately I didn't do the spring balance check before dismantling but I don't think it was much sloppier than my measurements below. Having fitted it back together the greatest release load I can achieve is about 10lbs on 1st/2nd and 8lbs on 3rd/4th. If I screw the plug down any further the spring bottoms out so the ball can't move out of the notch in the selector rod. I am using the spring balance on the threaded section for the knob, about 5" above the gear lever's pivot point. My springs are about 1mm shorter than the specified free length and from a quick squeeze seem to be of similar strength to each other.
I haven't touched the reverse selector as the plug seems to have been sealed and it ain't broke......
Questions:
Has anyone tried this procedure and achieved the specified loads?
Are the specified loads necessary, they do seem a bit hefty and I would prefer not to need to make changing gear a weight training exercise?
Do I just need new/stronger springs, or could there be something else causing my slipping out of gear problem?
Thanks in anticipation
