Way down on power, top speed of about 35 warmed up. Read about the history and technical specs of this legacy engine.

Unknown caterpillar c7 engine and engine cooling recall 11e051000.

Cat c7 engine problems. Cat c7 vs cummins 5.9. B10 is the average life expectancy of an engine measured in miles where 10% of the produced engines failed and needed a major overhaul. Seems to have a bit of a stumble on throttle between say 900 and 1500.

I have a 2004 freightliner with a cat c7 on it, experiencing strange loss of acceleration after it warms past 150 degrees. I hired a recommended mobile rv mechanic to look the motor over and he said that it could indeed be air in the fuel system noting that my cat c7 did not have a fuel primer, something i did not know. C7 #1 acting strange,complaint loss of power.they took it to dealer.dealer changed injectors,high pressure pump,pistons and rings,crank,cam,boost sensors.they took it for road test everything running fine than it started to push white smoke.shut truck off restarted truck running smooth than started.

Freightliner replaced ecu and sensors recently and i already changed fuel pump and fuel lines and filters and the very same sensors freightliner changed and changed injector seals oil and oil filter and so far it is sthe the same. Sir, we have a cat c7 that is losing coolant and we cant figure out where its going. Check the cat data link again.

Temporarily install a new ecm. Were the leak on the pressure side (after lift pump) instead of allowing air to be sucked into the fuel, you would have a fuel leak. I have heard the horror stories about the c7 and problems with the huie (sp) systems and the cost to fix them when they go out.

The 2004 epa (epa 04) compliant and the 2007 epa (epa 07) compliant model. C7 engines have problems with the fuel pressure regulator not maintaining enough fuel pressure especially when cranking. We changed the starter and it did the same thing.

I have heard that part of the difference is that the epa required cat to reduce the timing to reduce n02 emissions. The long and short of it is my 2006 itasca ellipse with the 350 hp cat c7 in pending a new engine in jackson, georgia. Traveling home from florida in the spring i began to have engine problems.

Going today to look at an 02 discovery with the cat c7 engine and also an '00 discovery with the cummins 5.9 engine. I think you need to understand two things about them: I will say that last week we thought we had a bad starter as the truck would only click once when trying to start it.

Cat c7 acert problems with diesel engine technology there are two rating systems to determine the average life expectancy of the engine: The rough history of the cat c7. I have a 2004 40 ft diesel pusher with a cat c7 rated at 330 hp.

1) the fuel injectors have a hydraulic boost built into them, with the hydraulic energy coming from the engine oil system. Oil level is correct, oil has about 2k miles on it and appears to. Check the high pressure oil system for leaks.

Discussion starter #1 jul 28, 2010. Therefore, around half of the cat c7 engines experienced engine failures at 500,000 miles and needed an overhaul. The truck doesn't leak anywhere weve found but it also doesnt seem to be going in to the oil and the truck doesnt seem to smoke.

Both fuel filters and air filter replaced. Advertisement at the end of its production cycle, the engine included a number of features including turbocharging, common rail fuel injection system, full electronic control system and caterpillars acert fuel/air management system. Check the cat data link for proper operation.

Does anyone know what differences are? The piston is only available directly from caterpillar or ipd diesel parts in a standard bore size. In order to start the c7 engine needs:

If the data link does not operate correctly, there may be a problem with the ecm. The two versions of this engine are: Broken valve caused scored cylinder and broken piston.

2) determine if your fan bearing is sealed or needs to be greased. Look at the injector bores for any signs of oil leakage while the engine is being cranked.inspect the spill ports on the injectors for an excessive discharge of oil. Engine runs fine while warming up but as.

Power to the ecm (your light comes on so we know there is power) a good ecm (your light comes on so we know the ecm is operating) the next thing you need is an engine speed timing signal Don't skimp on oil changes or filter quality. Since you do not have an ac signal going to the injectors while cranking, there must be an electrical problem with the engine.

The steel monotherm piston is a 1 piece steel piston used in some of the c7 arrangement numbers. You may want to make sure you are not sucking air. Unknown caterpillar c7 fuel system, diesel recall 10e025000.

It has been at georgia truck and rv. Connect cat et to the service tool connector. I am not sure what the difference is in this engine when compared to the previous years pre c7 cat 7.2 liter engines.

This results in a price increase over a c7 with the 1 piece aluminum. Both have around 50,000 miles. Remove the fuel filter(s) and make sure its full of fuel.if not install a fuel pick up hose between a bucket of fuel and the fuel transfer pump and try to start the engine.

A loose hose fitting, crack in fuel line between tank and primary filter or primary filter and lift pump, leak at primary fuel filter, etc. However, this does not differ much from some other diesel engines. However, things don't always go according to plan.

One of the engines cat manufactures is the 7.2 liter c7 engine.
