Trunk Lock Mechanism

[earlwb]

I discovered while on the way home today, that the trunk lock mechanism, more or less, fell apart on me. So I had to use a piece of duct tape to hold the lid down until I got home. Yes I carry a small roll of duct tape with me, you never know, as it is super handy stuff to have around.

Anyway, there is a little pin that passes through the two arms on the plastic lock frame. That pin vibrated its way out, after it wore the plastic down a little. Fortunately, the pin, the spring and the moving lock plate stayed in the trunk.

I am still not sure about the spring. I think the U shaped upper part, is supposed to be tensioned against the lock plate, but I am not sure as to where though. I got it back together, but the spring isn't tensioned against anything as far as I can tell. It is working Ok though.

Here is a view of the lock mechanism after I removed it from thr trunk box and put it back together. I used the upper U shaped locking arm to test it out before screwing everything back together. After reassembling everything, I set the upper U shaped piece on the trunk lid so it was short, and then methodically adjusted it down until it would start latching OK. I then tightened up the screws good.

I decided to drill a small hole through the end of the pin, and insert a simple saftey pin to help ensure the pin doesn't fall out again, anytime soon.

It's sights like this that make you appreciate the ability of the web and the time people put into to it. I have not had this problem, but; guess what.. something else to double check to verify working here in the garage, and not on the road many miles from home.

EarlWB, Thanks for the info and pics..

Earl, I just checked my trunk, and the spring loop goes under the latch piece which must just give it a positive push upwards when the button is pushed to unlatch the trunk. Good repair job tho, and another thing to look out for. Art

Hey thanks fulltimerart, I was thinking along those same lines myself too.
I sort of wonder if there was supposed to be a Circlip on that groove on the end of the pin or not. I suspect that was the original intent, but you know cost cutting, every penny counts.

Humm, I think I need to take a close look at the saddle latch mechanism now. Before anything not good happens there.

Well, I redid the lock mechanism and put the spring end like it should be done on the lockplate. So this is like fullermart mentioned above.
Basically you bend the "U" shaped part down on the lockplate, like shown in the picture below. Then when you release the lock, the trunk lid pops up a little. You can see the spring top bent down under the lockplate in the picture.

It looks to me like there shoud be an "E" clip on the end.


A proper sized hair pin cotter pin should work as well.

Wow, and I thought my Roketa latch was crap. Mine is all metal mechanically with a bracket bolted to the hardened plastic body. Yours is eventually gonna just deteriorate.

[earlwb]

yeah, more than likely.

I found my little box of cotter pins I got from Harbor Freight a while back. So I replaced the safety pin with a proper cotter pin.

Yes there was supposed to be a E clip on the end, but I doubt it was there when I recieved the scooter. I think they figured friction would keep in in place or they forgot to install the E clip.
