Yes, had to do 2, and stocked up on spares.. I was warned there was a knack, so YouTube to the rescue. The pins were rusted in, so ground the flush to get the tine holder out so I could punch them out on the bench. Put it back together, put the new roll pin half way in, 3n9ugh to hook the end of the spring into it before tapping it further in. It you punch it in to far before fitting the spring, it will be hard.Looks good.
Have you had to change a broken tine return spring yet................it takes a bit of working out how to do it.........i've heard of someone who spent half a day trying to change 1 spring.
second one was much easier than the first one. I can see how it would be hard without the YouTube videos.
