I have a New Holland 474 Haybine that I use to cut hay every year and it is in great shape. I am in the process of trying to replace the reel drive chain because it no longer has anymore adjustment due to being stretched. While I am doing this I was going to replace the white plastic idler (part # 770940) that is used for the adjustment of the chain and I am being told it is no longer available. Now, I actually located one at a nearby dealer but it is his last one. Wow, this just blows my mind. I believe this plastic idler was used on other popular models like the 489. I mean out of all the things that you can get for these machines, you can no longer get what I would classify as a wear part.
Anyways, for anyone with a decent background with these machines, from what I have understood from research the earlier years of these haybines used a metal sprocket for the idler and the later years used the plastic nylon idler like I have. Having said this, it appears that the metal sprocket is still available. My question is can I just convert to the metal sprocket in the future if I ever need to? Does it use the same bolt and hardware that the plastic one uses? Thanks
