How to stop the spring coming off

[neilbardsley]

This spring keeps coming off. I tried to put a cotter pin on but it didn't work.

Any other ideas?

You got the right spring Neil? Looks like they used 3 on the A:

23 644 511 511 00
23 644 531 547 01
24 644 531 542 00 (Small
Valid up to:
20.9.57)

File the groove out so the spring end fits into it better, then try and crimp that end further together?

Thank you. I'm not sure I do as the first time I tried to order on it was closed on both sides!

Have you compared it to the other side ?

If so, does the new spring look correct ?

What stops the one on the other side from slipping off the 'pin' ?

You could try using an appropriately-sized starlock washer pressed on to the end of the pin:

I haven't dared open up the other side. I agree the most logical thing to do is take the spring off there and get a similar one but they are so difficult to get on.

Yes I ordered some star washers just before starting this thread.

Are the springs in question correct?

When I worked, we made about 8 million car door locks a year just in the UK plant and tested the designs to death, some to over 250,000 operations under all conditions experienced in a car door.
Springs never failed (other bits did). We used top quality materials and manufacture, they were safety critical.
At the time we were 'allowed' 13 parts per 1,000,000 lock failures.

The right spring should fit and work. We did not use fancy assembly tools applying high loads to install them.

The simple answer is that the normal springs don't seem to fit. I measured the broken one when I took it off but can't find the thread.

Today after much playing I think I've sorted it. I loosened the ruler for the window glass. Then installed another spring. Which was much stronger but the door button couldn't move. I reinstalled the old spring with the clip then tried to push on one of the fasters Andy suggested but it was between two sizes so not a solution. Then I realised I could adjust the clip so it was shorter and tightened the spring on the latch. This worked and I'm happy the spring isn't jumping off. However, the pusher from the door button wasn't long enough. I couldn't figure out how to adjust so put a brake valve cap on! Now working much better.

I tried to clean the window runner batch and repaint but I'm not sure it's looking much better.

Rust inhibitor sprayed inside the door. I will do a couple of test drives before I put the door card back on
