Trying to repair New Holland 477 Haybine

Hi everyone. I'm trying to replace the connecting links on my New Holland 477. They're completely worn off, here's a photo, they're the links directly to the left of the wheel: http://i.imgur.com/kdRGpkw.jpg

We need to first separate the cutting bar from the axle. Do I do that by completely backing out those springs? Also, the replacement connecting links look big for my machine, but I don't see any other option. It looks like I may have to grind them down on each side that connects to the cutting bar part to make them fit.

I just got the service manual in the mail today and I was really disappointed to see that it doesn't even cover this, it's a pretty small manual. I haven't even been able to find any photos of what it's supposed to look like with the links attached.

Thanks for any help!
 
If it comes apart like my 479 and 488 did you do not have to loosen the springs. Just do one side at a time. Lower the head down on some blocks and loosen and remove the bolt on the axle first. Use a handy man between the header and axle to help take some pressure off. The fun will be getting the front pin out it has small bolt to keep it from turning and hopefully not froze in the link. I had to cut my pins. Depending on what is left of your links I have rebuilt the with angle iron and replacement top link balls.
 
Pretty straight forward job, I did at least a couple back when I had 477/478's. As was said, no need to loosen the springs, just get a porta power or other jack between the axle and head - you can probably get them out without that, but it'll be a lot easier getting them back in. As with most jobs like this, getting the old ones out is harder than putting the new ones in. A blue wrench sure helps...

eah it looks like I'm going to have to cut the pins, I got the nut/bolt off but it looks like the pin rusted right onto the old link and even if I got it off with a torch it'd be in rough shape.

So what tools exactly will I need? All I have are little floor jacks for a car, they may not cut it.
