Removing Cylinder

by **Wolf2486** » 16 Mar 2005 17:39

I have tried to remove the cylinder from this master lock with no avail. I used a drill to try and drill around the hull hoping the cylinder would just kinda fall out. No luck. I have picture of my already destroyed lock. Any help on how to remove this cylinder (without damaging the locking pins that hold down the shackle or anything that involves releasing the shackle) All I want to do is get the cylinder out, and the housing if necessary. Please understand I do not have access to advanced tools, just a drill, screwdriver, and a hammer. Thank You.

Not all locks are made to be dismantled like that. You may have to just take a dremel to it in hopes of cutting it out.

if locks arent made to be taken apart, you will have a hell of a job getting the cylinder out, the best thing to use would be some sort of file or a dremel preferably (the only file i have is on a penknife), if the cylinder can be removed, when you open it, there will be a small screw under the shackle that you have to unscrew to get the cylinder out.

What exactly is your goal here? Do you want a standalone cylinder to practice with?

It looks like a brass padlock with a decorative/protective cover on the outside. If it is a brass padlock, the cylinder can't come out. The whole lock is the cylinder.

What you might be able to do is remove the pins and springs and then take out the plug, but doing this is tricky and potentially destructive of the lock. There is a thread somewhere from not long ago that talks about this. See if you can find it by searching for "brass padlock", "cylinder retaining pin", or something like that.

You killed the lock. The springs/pins are probably lodged inside the hull, so the most you can get is the pins and the cilinder shell(not very useful on their own though).

Most cheap padlocks are not supposed to be rekeyable. I believe that the only rekeyable Master padlocks are the ProSeries. Check their website.

The key surprisingly still works. My goal here is to see how the locking dogs on this padlock work. I couldn't care less about the cylinder. I do realize that the hull IS the lock, but I do not think drilling the pins would open it, thus wouldn't turning the key just open it?

That post-mortem lock actually looks like a #140dlf. I, erm, did a post-mortem of a #140 (naked 140dlf) a while ago...just undress the dlf and the result will be the same.

Look here (10th post down...took a while to find):

After re-reading, I notice you don't have the major tools, but the ones you have will suffice...

Use your normal drill and try to just snag the plugs (which cover the pin stacks). As the drill starts to go through....STOP the drill and pull the plug out.

The 5th one (which secures the plug) may give you a bit of trouble though...the cover plug has to be removed firts, then the securing pin.

Alright I found the holes, can I just take out the fifth one, then turn the key to take the plug right out? Also if I drill the "big" hole, will the locking dogs spring out? I would prefer those to be intact so I can see how they work. Thank you

Yes, you could just remove the fifth plug (and securing pin), then use the key to remove the plug, but remember the drivers and springs will fly out...do this inside a plastic bag to save losing anything.

There's no need to drill the heel/toe locking bolt cover, just open the shackle and tap the cover from inside the toe hole. The bolts will not be able to be removed without the plug being removed first though...

If you wish to re-assemble this lock afterwards, you will still need to remove the plugs on pin-stacks 1 thru 4...

Alright I did everything (including removing the bolts) but the cylinder is not completely out. How do I get it all the way out, it rotates but is stuck?

by **master in training** » 20 Mar 2005 12:58

is any part of the bits you drilled holding it in, maybe a twisted bit of metal?

are you using the key to take out the barrel or are you just pulling it?

by **Wolf2486** » 20 Mar 2005 13:02

It's possible. I'm using the key.
