Trunk lock Problem

SuperDave

I have a 49 Super six with the lever type trunk latch. The lock cylinder had the tip broken off.This is a common problem with these locks I am told. The cylinder would come out easily with just turning and pulling the key. That was not "right". I bought a NOS Lock and key., I know the old piece that broke off is not in there. I place the new cylinder in the handle and it not only cames right back out.. it doesn't engage the handle to lock and unlock it.

1. It won't stay in. What is missing that "locks" it in? I can't see what is supposed to hold the cylinder in the handle.

2. The lock cylinder doesn't move the little spring loaded end that causes the handle to "lock". I can make the handle lock and unlock by useing a small screw driver inserted to the back of the handle and move the spring loaded thing, so it appears the handle is OK. Why doesn't the pin on the lock cylinder do the same thing the screwdriver does?

Anyone have any insight?

Thanks, Dave W. Fl

Dave,



I had the same situation as you, when I'd bought a new lock cylinder to replace my missing one, and couldn't figure out how to get it to stay 'in' the handle.



It wasn't until I bought a 'parts' handle at a meet (needed chrome, so I got it cheap), and tore it apart that I figured out what I was missing. I've got this all sketched out at home, and will have to refer to it and let you know what my specific solution was (on Monday)......it seems to me there was a small stamped sheet metal part that was lightly pressed into a recess in the handle that held everything together, that I didn't even realize I was missing, until I tore that other handle apart. Seems like this part would be real easy to lose, once the cylinder is removed. I'll have to double check my book.



Now, I'm assuming that I've presently got it correct, but I'm certainly no expert on this. This is how mine works now; when the key slot is facing 9:00 the trunk is 'un-locked', which is to say the latch handle must still be turned to 'latch' the trunk closed. Now, when I rotate the key slot 180 degrees to face the 3:00 'locked' position (using the key, of course) this allows the latch handle to still swing through it's range of motion, but now it doesn't disengage anything inside. Hence, it doesn't un-latch the trunk.



There is one 'quirky' thing about it, though. If you stop rotating the key at 12:00, the whole cylinder will come out in your hand! I guess that's how it's meant to be assembled. So I just keep a slight pressure in throughout the rotation of the key, and it works fine for me. It is nice to be able to lock my trunk now.

Quick reply without looking in the parts manual... but if memory serves me... sometimes it does and sometimes it dosent!... there is a C clip lock that fits the end of the lock shaft. When the lock is inserted into the handle assembly the C lock is pushed over the shaft end that turns the lock ... the C lock keeps the lock inplace.



Good Luck
