Help installing master link on 2040 roller chain

My New Holland 273 baler ate the chain that drives the knotters. The New Holland dealer sold me two 10 foot long chains. Each one has 120 links. The chain that I need has 151 links so I planned to use one of the chains with 120 links and 31 links from the other chain. I busted the chain that I want to use 31 links. Now, I'm stuck on the retaining clips on the two master links that I plan to use to build the right length chain.

The two retaining clips have a round hole and a groove for one end of the clip to put it onto one of the posts of the master link. But, the other end of the retaining clips have a cut in the end of them that should slide onto the other post of the master link. Unfortunately, the end that should slide onto the post has two prongs that are tightly touching each other. I can't slide the clip onto the post that it needs to slide onto.

I've watched some youtubes but each of them has a semi-circular end on the clip that easily slides onto the post. Mine don't.

Any ideas on how I can force that clip onto the post?

Thanks Fred. Do you set the clip on top of the post that you want it on or do you use the screwdriver to open the clip and then slide it into place. I must confess that I've tried both of those approaches with no luck. Obviously though, I didn't do it right or I would have had success. I am concerned about distorting the clip but maybe I shouldn't be.

Make sure the closed end of clip is facing the direction of travel. Slide the closed end onto the pin as far as it goes with the split end rotated down or up so clip sits flat against plate of connecting link plate while sliding it on. Then rotate split end of clip towards pin lifting up on the side closest to pin with a small flat screw driver so it slides over pin and snaps on. Its not that hard once you get the hang of it, but I prefer cottered connecting links as they are pretty much fool proof. We literally use miles of chain were I work and only use cottered connecting links for anything 80 and up as we have had numerous occasions were the clip type connectors have come off. Personally I think its due to either guys putting on with open/split end in direction of travel, and or not ensuring they are snapped into groove. All this said the clip type will work fine on your baler if installed correctly.
 
Thanks Tom,

I concluded today that I needed a third hand to hold the chain in place. press down on the link, open the end slightly with a small screwdriver, and tap the clip into place. Your technique sounds simpler to do, so tomorrow I'm going to draft my wife to help me, and maybe between the two of us, we can have some success.

Slide the connector onto the one post but rotated so the other end is not touching the post at all. Rotate it until it is nearly touching, then pry the end nearest the post up until the clip can be rotated to where the end that is not pried up is fitting into the groove. Now pry the part on top of the post until it slips over the post and into the groove on the other side of the post.

It took me 10 times as long to type that as it would have taken to slip the clip into place.
 
2040 is LIGHT roller chain, no tools or a helper needed.

Simply press one side of the lock ''down'' at the split end and hook it in it's groove on the pin, then catch the other, raised, side with your thumbnail and swipe it over the pin and press ''down'' on it so it also drops in the groove and locks.

This is not rocket science just put the small holed end over the link pin slip it so the other end will catch the opposite pin now just slide the long split end over the pin and push down and sideways with your finger or thumb to put the other side on. Done. No need for another person since the side straps are on by now. Then adjust chain tension. Took longer to type than really do.
 
After a whole lot of messing around, I finally got the two clips onto the two master links in the drive chain for the knotters on my baler.

I then tried to put the chain onto the baler. It was too short. The parts catalog specified that the chain needed 151 links. I meticulously counted the links MORE than once to insure that I had 151 links. It turned out that I needed four more links to get the chain to fit. I put the extra links in temporarily and then went back to the New Holland dealer to get more master links. The clips are much better than the ones that came with the chains. I haven't done it yet, but it's obvious that the links will slide right into the grooves in the links.

In any case thanks to all who responded to my post. I could not have figured out how to get those danged clips in without your help.

You are nearly correct that you need a third hand, but instead of calling your wife just rotate the sprockets so that the sprocket is holding the chain.
