It works but the battery door won't stay closed.

I found battery doors for sale affordably on eBay :

And I found low res instructions :

But I was hoping to get advice from someone who has done this repair.

For example, I don't think I have needle nosed pliers that are small enough LOL

Can I get some clues ?

Thanks!
Craig

Hello there.
The instructions in the second link are clear and detailed. Rotating the shaft while pushing it upwards with the pliers helps to free it more easily. It is important that the pliers are the right size, too big they won't fit, too slim they'll also be too weak and not applying enough grip. The motion of the pliers must be firm but not too strong, should they slip you'll scratch or break something. So get a suitable pair of nose pliers before attempting the job, that will be money well spent and will save you a grief. And, again, be careful to the tiny spring, working in small tray might prove helpful should it fall down.

Cheers, M.

At the bottom of the door the wire hinge pin is held in a groove by a metal plate. At the top the pin goes through a hole in the front edge of the body casting, at the top plate/body joint line. To loosen the bottom retaining plate requires a major strip down.

However it is possible to remove the pin with a good pair of engineers pliers. I have done this on many A1 bodies and I always remove the top plate so that I can see the movement of the pin. I have not done this on AE-1 or AE-1P so do not know if it is advisable to remove top plate on these. You are looking for adequate clearance between end of pin and any circuit board that might stop the pin rising far enough.

Open the door and mark the position of bottom of door on pin, using the pliers grasp the hinge pin in center and wiggle it upwards. You should be able to get it clear of the 'door frame' at the bottom. Gently bend the pin outwards so that you can slide the door off the pin. Do not loose the door spring. To aid the repositioning of the pin I remove it and grind a little 30 deg point on the bottom end, this allows the pin to slide behind the retaining plate. Replace pin in top hole, slide new door and spring on and gently bend back and push into bottom groove. When end has entered bottom of frame keep the pin in contact with rear face of front of body ie keep it in the groove until the mark on pin meets the bottom of door.

I suggest that you remove the good door first, so you get the feel of the job. When you have removed the door just try pushing the pin back into the groove. It is important that the pin is held by the retainer.

Also note that I do not bother to replace the door spring any more. It can be a fiddle and I manage without the little blighter.

I assume you mean those instructions ?

Oh the last few posts here are very descriptive too :
