Took the valve cover off and adjusted the valves on the #4 cylinder with Brennin surprisingly the tolerances for that engine where greater than the cummins Bseries that i worked on earlier. where the valves in the B series had to be .010 of an inch plus or minis .001 inch where the ISX could be anywhere between .014 to .020 of an inch.
Finding fault codes on the ISX was a little tricky because it wouldn't talk to the Modis scan tool but we had the laptop with Cumins Insite loaded on it and got several.
the one i chose was Fault Code #2367
Reason. Engine Brake actuator driver 2 circuit voltage above normal or shorted to a high source.
Open circuit or high voltage detected at the engine Brake solenoid #2 signal circuit
Effect.
Engine brakes on cylinders #2 and #3 can be on all the time OR can NOT be activated .

day 33 -37
Day 33
1. Cooling, The answer i got from the document Jeff had us read was that the larger the radiator the cooler you can make the engine. you dont want to make an engine run too cool and you dont want it to run to hot, so you have to have the right size.
2. Detonation. When the fuel begins to burn, it will provide power. (duh) But if detonation happens too soon or to late, it will have an advers effect on your power if it happens to late, and can harm your engien if it happens to soon (pinging)
3. Contamination. Besides the recomended matenence intervals, could an oil change be determened?
By how often the engine runs. how long it runs and its duty cycle. most off shore applications and in boats, its commen that regardless how much the boat goes out that the owners will have the oil changed once a year.
4. Combustion air flow requirments. finishing the statement "Combstion airflow requirements will vary depending on the specific engine model and rateing. spicific air flow data for caterpillar engines is given in both..." Volumetric and mass flow. at staderd reffernce conditions.
Day 34
1.The FCA is the Fuel Control Assembly and it regulates the fuel to the injectors.
2. High Preasure Fuel Warning
3. There are 2 Intake heaters for the Dodge 3500.
4. Vehical throws an Open code for all 6 injectors. meaning that more than likely the harness got torn off or disconected some how. the chance of all six going out at once and needing new injectors is slim. another possobility is the cam shaft position sensor is bad but did not show on this truck so that is still good.but if it did have a code then that could be why the truck is not starting.
5. Making the horn blow and wipers work with the scan tool is called "Bi-Differencal control"
Day 35
1. Scanning the Freightliner for codes came up with a barmetric preasure code that was shorted high.
2.(pic next) seeing the humps on the scope then seeing the longer one let me know that the longer signal was TDC for cylender #1
Day37
1. the 9 functions of oil. Lube, preasure wear control. cleaning, protection, cooloing, sealing, shock dampening, hydrolic action.
2.6 oil contaminits. Combustion biproduct, acid varnish, abrasives, fuel, coolent, soot, and enviermental contaminnts.
3. the 9 sets of data that must be included in oil analysis
Engine modle and Sn#
Miles/Hours of oil use
Miles/Hours since new or rebuild
Oil Used
Date Sample was colected
Engine Application
Amount of oil added since previous oil change
Any recent engine matenince
Analysis of new oil
4. The two methods to take an oil sample are, to use a small vacuum pump and draw a sample from the dipstick, or take some as its draining from the sump at an oil change.
5. ? Odd wording Jeff
6. I learned that the diffrent types of contamination wil lead to diffrent failers and exesive wear on certen parts depending on what type of contamination you have in your oil.

1.The FCA is the Fuel Control Assembly and it regulates the fuel to the injectors.
2. High Preasure Fuel Warning
WARNING:
|
HIGH-PRESSURE FUEL LINES DELIVER DIESEL FUEL UNDER EXTREME PRESSURE FROM THE INJECTION PUMP TO THE FUEL INJECTORS. THIS MAY BE AS HIGH AS 23,200 PSI (1600 BAR). USE EXTREME CAUTION WHEN INSPECTING FOR HIGH-PRESSURE FUEL LEAKS. FUEL UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE SKIN CAUSING PERSONAL INJURY OR DEATH. INSPECT FOR HIGH-PRESSURE FUEL LEAKS WITH A SHEET OF CARDBOARD. WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE CLOTHING WHEN SERVICING FUEL SYSTEM

International MaxForce
Over the week myself and Brennin where using the computer on the International outside.
Seeing the different things that the computer is able to see and tell you was interesting. and using the software to fill out the Hard Start No Start sheet and the performance diagnostics sheet.
one test we had to warm up the coolant in the engine and to do that we did a high idle which for that truck the limit was just after 2600 rpm after that the truck would shake and not like it. then what surprised me was some of the tests from the computer would make the truck do different things on its own.
we hit the run test button and the truck behind us reved up and did its own thing.
