...............CAT brand parts.......

I have a set of their roller rockers... had one of the adjuster bolts break, then as I was adjusting them, another one broke.... I took them off and called and they sent me 3 adjusting bolts free. They were going to sell me a whole set for 25... anyway, they are still sitting in my shop all wrapped up.... I may put them on again but I would sure be leary of them....
