Dear all =)

I disassembled one of my old Ruko 2 padlocks which was key retaining, but when I put it back together it was not key retaining any more. To my knowledge haven't I lost any parts.

Can anyone explain how I can make it key retaining again?

Jasmine =)

Update

Here is a picture of the cylinder from the back.



and here is a picture from another Ruko2 which still have key retaining. I dare not taking this one more apart before I know how it works.

Do you have a photo of the back of the cylinder?

My gess is that you put the "H" shaped thing upside down its probably a feature of the lock

Wait, old Ruko 2 padlockS? As in plural more than one?! I reckon a collection thread of yours is in order!

Sure. I have now updated the OP.

It can't be turned upside down. Only the part with the wide space fits between the holes in the bottom plate.

I'd love that, but I only have two so far =)

I am however from the land of Ruko, so I hope I can pick more up at the flee markets =)

Well now I am confused.

My only guess is that the cam might have been put back 180° horizontally the wrong way. Either that or a ball bearing is missing?
Sorry, I thought a photo might help.

Looks like you're missing a 90degree curved clip

But i could be wrong

My guess that lock was never key retaining only the other lock is. By looking down into both locks if you look at the part that actuates the ball bearings in the one you can't make key retaining you will notice it has a different ball bearing actuator it is cut away in a butterfly looking groove that H bar goes into so the key can be turned back and removed when open. Now look at the one you say is key retaining. I can't see it cut away in that picture away it looks like a straight groove and the plate that goes on the top has NO post for a spring at all as it appears the actuator is right up next to the plate that goes on top. Take a look down at the key retaining one and see if there is no room for a spring between that top plate and actuator plus no post attached to the top plate. Here is the first clue that shouts out to me it was never key retaining as one that is key retaining doesn't need a spring as you have to manually turn the key back to lock it. Just closing the shackle will not snap locked automatically you have to turn the key back manually I believe. Does your key retaining one snap locked or do you have to turn the key back? The exploded view shows the bar is attached to the actuator and no spring on key retaining models and have 3 ball bearing. Maybe I am wrong but don't so.

The assa catelogue is "current" i would believe the lock in question is an older design
But as i cannot find any information on older rukos(im looking for information on another old ruko
Best Discription-body looks similar to a master dial combination padlock. Where the dial is looks like a ruko
Display cabinet lock cylinder)

But I digress, the catelogue example is just as a evolution of the designs within the company.

Mrwizard. I agree taken on face value, the parts in the first photo would be only the spring loaded.
However the "dog bone " plate in the 2nd lock is identical.

I am talking about Jasmines pictures. In the second key retaining lock she has pictured the actuator under the plate looks like it is right up against the plate with no room for a spring or spring post and don't see the butterfly cutaway so the key can be turned back to the left it is solid on the left side so it can't be turned back to take key out look at it. Picture says the second lock is different unless it is a magic illusion. The C clip you say might be the problem looks to be the cyld plug retainer. But until Jasmine comes back to say what she sees up close no reason to continue speculating.

In the absence of the physical lock in my hands all i do is speculation

Jasmine when you figure it out, please post the answer
I would love to find out how it works.
