I searched and can only find instruction/manual for take down for a small frame. Is there a large pistol (741) service manual or take down/disassembly instruction?
The small frame shows how to remove the side plate. My 741 doesn't have a side plate.
I found this
"you don't have to remove the mainspring or the guide. Once you have
the grip off there is an allen head screw on the right side of the
frame, take that screw out, cock the hammer, screw that small screw in
where the grip screw goes (it holds the mainspring). decock the gun, you
will have to at minimum screw the elevation screw all the way up, if
not actually take the rear sight off. to remove the hammer, pull the
trigger back just a little bit and knock out the pin to the right, pull
the trigger all the way back and hold it there, lift the hammer out.
then flip the gun upside down and push the u shaped piece behind
the trigger guard forward, pull the rear part of the trigger guard down
notice the notch in the front that it rocks into and remove the
entire bottom piece that holds the trigger, hand and transfer bar (pay
attention to the way the transfer bar is attached to the hand, it likes
to fall off and the spring is delicate) then there is a u shaped piece
up in the frame that holds the cylinder in the frame (it's in front of
the cylinder bolt (stop) you will want something like a dental pick to
get it out if it's tight) and remove the cylinder yoke, look at how they
have the cylinder stop placed in there before you take the cylinder
yoke assembly out. that's all there is to it, it sounds harder than it
is.
Reassembly tip: when trying to get the trigger assembly back in the
frame, pull the trigger and hold it all the way back, get the hand in
place in the frame, and from the top use a screwdriver to rock the
transfer bar into the guide in the frame as you slowly let the back of
the trigger guard down until the bar goes forward into the notch, then
rock the trigger guard into the notch on the front and latch it in the
rear. you should be able to pull the trigger and rotate the cylinder and
have the transfer bar come up into place, if it doesn't do that it's
not together correctly. it does take some time to get it your first
time, this is the hardest part of working on the large frames.
