Normal coolant temp is 185-190 but will rise to 205-210 when running WFO. Are these 700HP C-12? I have a 03 mbl c12 is it normal for the boost to very from 20-28 psi through the whole time while climbing a grade in 9th gear? Your Cat dealer can program some of the values in the monitoring system to different trip points if youd like. Check "plumbing" between turbo and CAC and CAC and engine. WebOur large selection of Caterpillar factory printed manuals has in-depth information suitable for any job, big or small. Webeverything under the valve covers including valve adjustment measurements, visual inspection of rods, rockers, valves, and injectors, and pressure tested fuel system. As kind of an experiment I turned the MP-8 on and boost hit 31 - it dropped two gears but when it shifted back into 5th the alarm and check engine light came on. This started about 8 month ago. This started about 8 month ago. There is also a wide range of optional No obvious cracks around turbo. Step-by-step diagnostics Troubleshooting procedures Wire diagrams Pinouts Ohm and voltage readings and more!

When the engine is stopped, the absence of boost pressure allows the plunger to rise to the open position, which allows condensation from the aftercooler to drain out.

That is well above the green band. Something as simple as a broken hose clamp could allow boost pressure to blow the hose off. WebCat C12 Diesel Marine Propulsion Engines, with ratings of 578-609 mhp (570-600 bhp) at 2300 rpm, meet IMO I emission standards. Brett katlen86 Members 11 posts Report That's correct according to the techs at the CAT dealer and consistent with what gruse and birdhunter have observed. Anyway, the Cat C12 12.0L engine makes up to 445 horsepower and 1,650 lb-ft. Its not quite as capable as the larger C15 or the C13 successor. Only show this user. I'm in the uk and have a CAT C12 in a tipper -dump truck. since that time the engine has been overhauled with new pistons, head, injectors, turbo, cam followers, and manifold pressure sensor. Brett katlen86 Members 11 posts Report I only get 12psi to 15 psi of manifold pressure now. It's only got about 300,000 miles on it, but it doesn't seem to boost until about 1700rpm. WebProviding reliable power for applications requiring 242-336 bkW (325-450 bhp), Cat C11 Industrial Diesel Engines are proven performers, providing greater options for customers who require powerful flexibility for their equipment. Cat C12 diesel engines weigh in at 2,070 lbs, so uses are mostly limited to larger trucks, buses, and machinery. May 14, 2007. Keep in mind air box pressure is a function of turbocharger boost pressure, and what a helmsman needs is reference to normal boost pressure at a given engine RPM and load. No obvious cracks around turbo. I used to get 27 to 30 psi. Still no power. I can barely keep a 42k load going 70. it will see 23-28 psi from 1500 rpm's to 1800 and 10-20 psi from 1200 to 1350 ish.

I have a 03 mbl c12 is it normal for the boost to very from 20-28 psi through the whole time while climbing a grade in 9th gear? Running about 60 mph on cruise control it would shift down one gear and hold about 55 mph. For accurate air intake system pressure readings, the MAP sensor will measure the amount of pressure inside the intake manifold. The boost ran about 26.6 going up the mountains north of Redding. To add another data point to your original question about boost - our C12 typically generates 22 psi boost under full load-full speed conditions. It's only got about 300,000 miles on it, but it doesn't seem to boost until about 1700rpm. Its operating range is 1,200 to 2,100 RPM. 2.
