I have the FEL repair kit on my CK30 KL130 loader. Based on what my dealer told me, it has been on the loader for at least 5 months. I bought the tractor used and I have only had it about 6 weeks. It is like the kit on the KL120 loader but heavier duty. My dealer told me he puts them on all the loaders that come through his shop, if they are cracked or not. He gave me the impression that he has done 15-20. He did say that the kit didn't fit correctly on one loader. When I was tractor shopping, I did have a local dealer, who is often in the top 5 in sales in the country, tell me that there is not an issue with the KL130 loaders so there is no need for a repair kit.
It makes me wonder why the two dealers have such different opinions on the loader issue.
