Also be sure to ask your dealer for some Cat help, those lines should never ever break or crack, they are designed to last the life of the machine. At least that would be my argument for some Cat or dealer policy money. They have dollars set aside for customer assistance, and if you are a good customer or are nice about it, they will usually give some help. We tend to call our friendly PSSR very often, for advice and also help on the 'weird' stuff.
Good luck!
