9CK07502 whats the max rpm for this engine? it is in a RV if it makes a difference
Technician: Cat Man, Cat Engine Expert replied 4 years ago

Customer reply replied 4 years ago
ok thats what i thought. It normal for the throttle pedal to take it up over that? I don't know how high it could go but it will easy get to 2500 for sure. I was thinking that on the C15 engines they won't go over 2100 even if your flat on the floor no load.
Technician: Cat Man, Cat Engine Expert replied 4 years ago
Wow. No should not go that high. Should Max out at 2120.
