I have a Yugo Lafette that is generally in nice shape and complete, but with a battered paint finish. It was also totally packed, inside and out, with cosmoline and what looks like straw (must have been packed in a crate with straw?).
After a lot of struggling I was able to undo the rear pegs that hold the recoil sled to the Lafette frame, and undid the front axle and cotter pins. I now have the Lafette broken down into three main parts - fire control group, sled/mount, and legs/frame.
One issue I am having now is that the elevation wheel on the fire control box stopped working. I did not take anything apart here, just removed the unit as a hole from the recoil sled and arc shaped track. While cleaning, the wheel worked fine, and it would turn freely and the center piece would ratched up and down. Then, it was just frozen. The two adjustment levers set behind the wheel are also now frozen. I did take the cover off the wheel (screw, washer, wheel housing, large spring). I do not want to try to go further.
Also, how do you take the nuts that hold the large, triangular wing nuts in place on the two main legs?
