Sargent and Greenleaf Small Environmental Padlock Teardown

Picked up one of these off eBay without a key. Since it is necessary to disassemble the lock before making a key, thought it would be good fodder for a post.

Image

This is the model 0883, which is the little brother to the large model 0881, best known as the railroad padlocks. These are smaller in every respect, with a much smaller shackle and even the key is far smaller. This model uses the same keyway and can use the same blanks as the Abloy Classic locks. The first one I got actually had an Abloy Classic key. For this one, I got my grubby little paws on some S&G blanks for this baby. But first, to disassemble.

Open the lock since the shackle must be lifted to access the disassembly set screw. The set screw is accessed through this hole on the top side of the lock on the toe side of the shackle.

Image

You will use a .05" allen screw to back off the set screw.

Image

Once the set screw is backed off or removed (in this case, I removed it), the cylinder cap on the top of the padlock body needs to be unscrewed.

Image

It will no doubt be stuck a bit, so use a very small hammer or mallet to tap an allen screw that is fitted into the hole in the cap. Keep rotating it until the cap can be removed.

Image

Image

The bottom of the cap has a peg that fits inside a spring shown soon.

Image

Two sides of the cap have grooves in them where the set screw fits to keep the cap from being spun off.

Image

Looking into the hole when the cap is removed, you see the spring mentioned above set into a hole in the actuator. Note the actuator orientation in your lock - that raised part in the middle is offset. When in the unlocked position, the side that is more heavily cut away will face the shackle toe.

Image

For disassembly, I am using a generic Abloy Classic key blank.

Image

Make sure that the key has turned the actuator to the fully unlocked position. Ignore that I am using a blank in this picture. I had my reasons. :twisted:

Image

Remove the spring from the actuator.

Image

lift out the actuator.

Image

Here you can see that offset center raised area of the actuator. That is so the locking balls (which are different sizes, too) can be retracted the correct distance to allow the shackle to be raised without coming all the way out of the lock.

Image

One side of the actuator. That groove in the bottom of the actuator allows the actuator to mate up with the cylinder housing below.

Image

Image

Looking back in the lock body, you see the cylinder housing.

Image

Tip the lock to each side, shaking the locking ball into the opening and remove. Remember which locking ball goes in which side since they are different sizes.

Image

Image

At this time, you can remove the shackle. There is no shackle spring. But I took the pictures with the shackle still installed, so that is how you will see the pics.

Turn the key to the locked position and remove the key. If you have a blank, use one. If not, a straight wire coat hanger will work fine. Turn the lock upside down and use the key blank or wire to push the cylinder housing out of the lock body. You can see the cylinder housing starting to poke out of the lock body at the bottom of the picture inside the shackle. (That is why I left the shackle in place for these pics - you can see orientation of the lock body).

Image

Remove the blank as the cylinder housing slides down since the key bow won't fit inside the keyway hole. Keep tapping the lock upside down to get out the cylinder.

Image

And out she falls!

Image

Here is the cylinder housing. The bare groove in the side of the housing has a matching one on the opposite side. These are where the two sidebars fit, one on each side.

Image

Image

Image

Now I am removing the shackle that could have been removed above.

Image

Here a key blank comes in very handy. Not essential, but keeps things oriented well. Remove the discs and spacers, keeping them in order.

Image

On one side of the stack, you will see the narrow individual gates. On the other side, the wide gates that prevent the discs from being turned too far.

Image

At the tip of the key is the first disc. Note the number on the disc. In this case, 4. Keep track of which way each disc is facing which way and where the gates are located.

Image

Next comes a spacer. Note that on the triangular shaped spacers, the corner with a gate in it faces the wide part of the discs.

Image

The second disc is a B. Spacer. Third is a 3. Spacer, followed by 2, 1 and another 3.

Here are all the parts (except for the set screw which I forgot to include in the pic. :oops: Also you can see the S&G blank that will become the key.

Image

The lock body, discs and spacers:

Image

The rest of the parts:

Image

Now am going to show the discs in pairs. A 1 disc flips over to become a 4 disc!

Image

Image

B flips to become a D.

Image

Image

And a 2 becomes a 3.

Image

Image

Now to make a key. Lay the key blank along the housing with the discs and spacers installed. Use a fine point Sharpie marker to mark where the center of each spacer is located.

Image

Cut the bitting as required for each place, testing the key in the cylinder as needed to be sure the gates line up with the sidebars. Your key will end up like this one, except your bitting most likely will be different.

Image

Reassemble the lock and test your key.

Image

If correct, the key will turn just over a half turn.

Image

Woo Hoo!!!

Image

Hope this was worthwhile for you.

EXCELLENT write up! Thank you for taking the time to post this. Very thorough, except you missed a few steps between having the locked lock with no key and getting to the disassembly screw :smile: Is it safe to assume the bigger brother is constructed exactly the same way?

Nope. The bigger brother is similar, but not exactly the same way.

As for the missing steps - I'm not keen on posting that since the railroads use this smaller lock, too.

You must have had one hell of a show last night! It looks like a volcano up there today.

Re: Sargent and Greenleaf Small Environmental Padlock Teardo

Not really. The largest part of the fire has moved to the other side of the mountain. It originally started on this side, though. And it looks like it is building up in Romero Canyon area on this side again.

For those who don't know what mdc5150 is talking about, there is a wildfire going on the mountain a few miles from my house. Here are a couple videos. The first is an airdrop of fire retardant that I took from my back yard. The second is also from my back yard of a time lapse of the fire over about 9 hours or so that my son took a few nights ago (the second night of the fire) when the fire was really bad on this side.

That looks like quite a show to me. I have never gotten to see the DC-10 operate in person. They did a good job you can see where the fire retardant kept the fire from creeping do to the houses.

This is the south side today.

And another from Gordon's side of the mountain. I was just thinking monsoon season is going to be dangerous this year with all the vegetation gone on those steep slopes.

And the lightning will be starting many more wildfires once the monsoons get kicked into gear.
