Sigurd She has a Cat C15 550 HP engine in her. She came new in 75 with a 12V71N 431 HP GM and in Sept 1980 while turning around at Spencer Log Dump the key dropped out of the camshaft on the right bank and dropped into the timing gears!!! That put an end to that right there. The Shop decided that she would be a good candidate for the 3408 install. Mike Murphy had already been doing this down at his new Sarita Division Shop with huge success. He was using the 3408 Pre-lcup model 450 HP whereas Franklin went with the Direct Injection model. I liked the pre heater on the precup engines but the direct injection was without a doubt a nice starting engine without it. So for 22 years she was powered by that and when Hayes Forest Services took us over in 2003 she was rebuilt to their standards and had the new C15 installed. The nice thing about them was they have an excellent jake brake whereas the 3408 never had an exhaust brake or anything like that so it was nice that way! The C15 has been a very good engine from a drivers point of view Good power good fuel mileage . The only real complaint if there was one would be the exhaust manifold. For some reason Cat has problems with their exhaust systems. With the C15 it is the wraps on the manifold and the old 3408's was the exhaust elbows on each side. With the 3408 I never got the exhaust temp over 900 degree's where the C15 is running at 1200 degree's all day long. It will turn a new chrome exhaust pipe blue in a matter of days. However that is a small matter -- one you watch for. We have a few 60 series Detroits and some N14 Cummins. The C15 is by far the most popular for our work environment.
Great picture KPhelps , so much history and so few camera's , check out the thread "Back in the day " for more pictures of that era . Do you know what outfit owned it ?
Always a pleasure to see a new member. Is there a reason for the sled being so unusually long?
