Issues with hay dogs, on 278 New Holland Baler

I'm having issues, installing a new pin, and spring, on my 278, Baler. Having a Very hard time, getting the spring pushed down. Is there a way, to get the spring pushed down? I had changed a pin, and spring, a couple of years ago, on this baler, and I can't remember, how I was able, to get the spring installed. Your help, and advice, will be greatly appreciated.
