There are some "sickle servicer" machines that were made, Johnson was a popular one. If you cannot get access to one of those, then the old fashioned way to install a rivet was with the backside of a ball-peen hammer. I finally figured out what the peening side was for. Place something solid behind the rivet head, then strike the unformed side once or twice with the hammer portion of the ball-peen to enlarge and set the rivet. Then use the peening side until you have formed a head on the previously unformed side. It is actually easier than it sounds, the hammer does it naturally.

if you don't have the service tool handy you can remove the knives with a vise and heavy hammer. Open the vice just enough to insert the knife with the bar itself resting on the vise top. Do not tighten the vice onto the knife. Grab a heavy hammer and hit the top of the knife hard a time or two (or three) and the rivets will shear off. The last two will need to have the heads ground off and punched out. If you want you can also grind off the heads and punch them all out. Then you can install the new ones using Rick's method.

If you can find a servicer then it becomes easier.

It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.
