Mosler Safe

[Cepasaccus]

I am sure this dial is not a Mosler dial. I don't know how they got a matching dial, because the spindle threading of the 302 is quite unusual. The last patent number on the lock cover is from 1985.

I wouldn't be to sure about that not being a Mosler dial. Yes unusual to be found with a Gr. 1R lock, but it does look familiar. Mosler made a ton of different products over their 125 + year run.

You might be right.

Doug was right as Mosler have made ton of differ lock. Just by look at any Mosler dial would be hard to tell What the inside combination lock it. All i know they have change there lock so many time it hard to tell. This is why some of the old safe in past would be hard to get information on these lock.
Yes is it Mosler dial ring as can still buy them today. I don't remember who took over Mosler Lock Company ....Tim.....

I went through some of my pics of Mosler and did find one small square door with that same dial and ring. But I would be absolutely amazed if you could get one from Diebold. Heck getting older Diebold stuff from Diebold can be a challenge.

Yes do know that Diebold almost like the Mosler dial ring Also there replacement part call Big Red for the Mosler 302-402 per attachment....Tim...

Sorry to drag up an old thread, but it pretty much sums up and goes along with the problem/question I have. My 302-402 doesn't have the change index but it does have change key hole on back. The current combination is set to 50-25-50 to open the lock now. Say I want to change the combination to 53-13-30. If I am understanding the instructions correctly to do that I need to dial in 60-35-60(adding 10 to the current combination). Put in the change key and then dial in the new combination I want to use (53-13-30) take out the change key and try the new combination. Or am I misunderstanding a step or doing something wrong?

Hi Keith, That dial does not at all look like it belongs to a MRK-302. Everything in the change is relative to the missing change index. In don't have a MRK, but I have a dial that probably came from one. The change index is about 9.5 numbers left. Maybe your 10 numbers are ok though. So add 10 or 9.5 to the current combo and dial it in. If the change key fits then your are on track. Turn the change key and dial the new combo with the same offset added. Turn the change key back and remove it. Don't forget to test the new combo at least three times before closing the door.

Thanks for your help, got the combination changed on the first try. The lock is installed on an old TEL KEE key cabinet. The dial does not turn very smoothly I think the lock needs some cleaning and maintenance, any suggestions or tutorials for doing that?
