- I have a cat c7 350 hp in 2006 Itasca ellipse W. It just seems to go over the hills very slow. It will drop down to around 35 mi/hr on some long hills. The rig had about 48K miles when we bought it and now about 66K. It weighs in around 30K lbs with about 4K lbs TOAD behind it.
- The IAP Control Valve is an electrically controlled. Pilot operated pressure control valve. The Injection Solenoid (11) Actuation Pressure Control Valve is used in.
- File Type PDF C7 Cat Engine Injection Pressure Sensor Location engine speed is above 100 rpm and the actual injection actuation pressure is at least 6 MPa (870 psi) while the engine is cranking. Repair: If a 94-11 code is active or logged, there is a problem with the fuel supply system.

Cat C7 Iap Valve Locations
I can't seem to find the information I need to work through the valve lash adjustment on my C7 CAT engine. From internet searches I have done, the procedure may be similar, if not the same, for the 3126 or perhaps earlier models in the FMTV class.
I have the adjustment sequence and the specs so that's not the issue, however, 2 things are confusing me.
1) finding top dead center (TDC) for #1 and #6 and...
2) turning over the engine manually so that I can accomplish the first step.
I think I can confirm TDC from the position of the intake and exhaust valves if #1 is actually at TDC, but I need to manually rotate the engine to do that. There is also suppose to be an indexing point(s) on the flywheel where you can insert the appropriately sized bolt into that I have yet to locate on the housing.
On cars and trucks that I have done in the past, all you had to do was put the appropriately sized socket on the big bolt/nut on the front of the engine and turn it over in the proper direction. However, my engine has a freewheeling fan clutch and not a visible bolt that I can see to grab on to. I saw in a TM that you are suppose to be able to turn over the engine by grabbing the alternator belt, SERIOUSLY? I obviously haven't tried this yet, but I can't imagine a big engine line this turning over that easily.
So...if this process has been described elsewhere on this great forum that someone's aware of I would appreciate someone pointing me in the right direction, however, for those of us who want to tackle this procedure, it would be nice to see a thorough documentation of the process which I will do if I can get beyond square 1.
Thx,

This variable valve actuation also allows for the CAT C7 to offer an integral jake brake on two of the heavy duty diesel horsepower models. The fuel delivery system on the CAT C7 is hydraulic electronically controlled unit injectors for the mid horsepower models and mechanically actuated and electronically controlled on the higher horsepower.
