Abus 72/30 gutting

Here's a teardown of an Abus 72/30 with some tips on gutting them.

The keyway is fairly open but some with some warding. I've seen some other cores with different keyways but I don't have any to photograph.

To remove the core, unlock the padlock and depress the button in the shackle hole shown below, while sliding out the core. I used a shaped piece of wiper blade as a probe.

Here are the core, body, shackle, bearings, and actuator. Note, there is no spring on the actuator or shackle.

Below shows a pin in a cutout in the back end of the bible that limits plug rotation. Depress this pin with a probe and rotate the core over 180 degrees.

Now is a good time to remove the keypins through the openings in the bottom of the core.

I have found that Euro cylinder tools work best for removal of these cores but a regular follower can be used with a slight modification of technique. Use the tool on the right to depress all the drivers and the pin which limited plug rotation.Then slide out the plug.

Below show shows tool placement and the plug out.

Here you can clearly see the pin and the channel it travels in which limits plug rotation.

Now all the pins are out you can see that all pins are standard and the drivers are balanced in length with the keypins.

The bible is very short in this core, so the drivers are cupped to allow the springs to go into the pin.

Now that its all apart make things a little more fun.

One tip for pin modification: due to the cupped drivers be very careful not to over tighten them in a dremel or drill chuck as they will deform easily.

Not used to seeing cupped drivers on this 'low end' a lock. Not that Abus is a bad lock.

I hadn't seen them before at all, but I am FAR from an expert. Looks to be a space issue mostly, as the bible and lock are quite small.

Have only seen them on european locks such as LIPS, Kaba, and Elzett. That is because a euro-profile lock has very little space outside of the bible for driver pins, and so locks that use pins from more than one angle need to find a way to make it work.

I like the keyway. In the Abus catalogue it shows a proprietary model 888 keyway. I've looked for one in an 83 style core to no avail. Great job and excellent pictures. I want one

Did you read the keyway? It says ABUS. Seriously.

I never would have spotted that. :shock:

Sargent has cupped drivers for LFIC. They are very unnecessary though for that large of a cylinder.

Do you know of any retail source for these 'cupped' driver pins (to fit the 72/30)?
