Lockbar sight removal

How do you remove a lockbar sight? Does the locking bar screw off? I seem to remember that the pinion (??) was staked to prevent the bar from being lost.

If that is correct, how much force is needed to get the bar off? I have turned it as far as I feel comfortable and it will not come off. I really dont want to break something if I can help it.

The reason for removal is to put the sight on another rifle.

Thanks for your help

Jim

Okay, I'll take a stab at this one. The bar is staked on. I just keep turning it up until it hits the stake. Back it down, do it again and again. Use firm pressure. Eventually, unless Mongo staked it, the bar will come off. Be careful so as not to lose the spring and detent under it. Reassemble and stake it. The Army had a staking tool. A pinch or mail set will work too.

Captain Emo has it right, but I would add a few thoughts. Oil the threads with a good penetrating oil like Kroil or Liquid Wrench. Add a drop from time to time to keep things wet. Bring the lock bar (They call it the nut.) up to where it wants to stop and force it 1/4 more turn and back off. Repeat this until the locking bar nut comes off. Inside the windage knob is the lock and spring. The lock has a D shaped hole through it that conforms to the flatted round on the end of the pinion shaft. Because of the staking, the very end of the pinion shaft may be upset enough that the lock will not slide off the shaft. If this is the case, use a small file to gently reflatten the end of the shaft to match the rest of the shaft.
After reassembly, I don't bother to restake the shaft. Staking was meant to keep GI's from loosing the lock bar or nut. That's probably not a problem today.

Here is an exploded view that should help:

Thanks, I was not sure if I was about to break something. It is pretty tight, guess its supposed to be.

Will get to it.

Jas, thanks for the great picture for the lock bars. I was hunting for one last week after I dismantled my lockbars to install on a rifle and quickly found myself lost!

Just to give credit where credit is due, that photograph can be found in Scott Duff's excellent book, "The M1 Garand: World War II". I highly reccomend it.

OK, got it off. I was not applying enough force to the nut to get it to turn past the staking on the pinion.

Now, anything special about putting it back together after cleaning? Grease, oil, ??

Thanks again for the information and advice.

Just remember to restake it when you re-install and get them adjusted. This is why the T105E rear sight was developed. John C. figured out a better way to do it. Nothing worse than losing a lockbar in the middle of a match
