18 What’s New Eaton Top II Eaton Top II New Gear Fast Run Slow flash files. (GFRS) New Gear Fast Run Slow flash files. (GFRS) On GFRS flash files the transmission style will show up as Eaton Top II. The transmission style is not programmable with the GFRS files. On GFRS flash files the transmission style will show up as Eaton Top II. The transmission style is not programmable with the GFRS files. Only for Eaton Top II Transmissions. Only for Eaton Top II Transmissions. Change in flash file from GFRS to other flash file requires factory passwords. Change in flash file from GFRS to other flash file requires factory passwords. Changing the transmission from Eaton Top II to different transmission will require a different flash file. Factory Passwords are required to make this change. Changing the transmission from Eaton Top II to different transmission will require a different flash file. Factory Passwords are required to make this change. Transmission Neutral Switch Transmission Neutral Switch Neutral Switch is located on J1/P1:62 or over the 1939 Data link. Neutral Switch is located on J1/P1:62 or over the 1939 Data link. Neutral Switch is now programmable for all transmission styles. Neutral Switch is now programmable for all transmission styles. This can affect Fast Idle, PTO, Elevated Idle, and Cruise Control.

Important to check neutral switch programming and operation if there is a complaint with Fast Idle, PTO, Elevated Idle, or Cruise Control. Caterpillar ET 2003B is required. Caterpillar ET 2003B is required.

19 Reminder  Outside Temperature Based Idle Shutdown –Installation of sensor kit is required when the idle shutdown is programmed to “Outside Temp Based” If this kit is not installed the idle shutdown system may not function properly. –The sensor kit must be mounted so an accurate measurement of the outside ambient air temperature can be taken.  Flashing ECMs –Always transfer the flash file to the hard drive of your computer. Computers communicate faster when the file is on the hard drive. –Also try the bypass harness. There is a lot of information on the data link from other devices such as ABS, or transmissions. This isolates the ECM from this noise. –By putting the file on the hard drive and using the bypass harness this will allow a ECM to be flashed in less time. –ACERT flash files are too big for floppy disks. Do not download ACERT flash files to a floppy. The flash will abort. File needs to be on a CD or downloaded directly from SIS web to the computer you are using to flash the ecm. Files downloaded to a CD still need to be copied to the computers hard drive.

20  Is this “overcooling”? Overcooling Troubleshooting

21 Overcooling Engine Discussion  Definition: Overcooling can be defined as the condition where the normal temperature at which an engine operates cannot be reached. –This condition is most commonly reported as: –Engine coolant temperature runs cool only at idle. –Engine coolant temperature runs normal at idle, but overcools noticeably while driving or operating in cool ambient temperatures.  The recommended minimum operating temperature for diesel engines that operate on high sulfur fuel is 80C (175F).  This can be achieved by elevating the idle to 1000 RPM. This results in the engine adding more heat into the system. –Customers operating engines with temperatures below 80C (175F), may report several of the following complaints: –Reduced fuel economy

22 Overcooling Engine Discussion  6NZ C-15 “Primary source of heat into the system”

23 Overcooling Engine Discussion  BXS C15 “Primary source of heat into the system” Precooler

24 Overcooling Troubleshooting  From the Troubleshooting Guide  Engine Overcooling  Probable Cause  Long Idle Periods - When the engine is running with no load, only a small quantity of fuel is burned. Therefore, the heat from the engine is removed too fast. The check valve in the vent line may be missing, or the orifice in the vent line may be missing. When the check valve or the orifice is missing, too much heat is removed from the engine.  Very Light Load - Very light loads, a very slow speed or downhill travel can cause overcooling. This overcooling is caused by the low heat input of the engine. The installation of shutters helps to correct this condition. <<“Shutters Dated”  Faulty Water Temperature Regulator (thermostat) - A water temperature regulator that is stuck open can cause overcooling. Overcooling also occurs when the water temperature regulator is stuck between the following positions: open position and closed position. Coolant leaks that are around the water temperature regulator can cause overcooling. An example would be a vent line leak. <<“how do you check”  Thermostat leakage rate is 10cc/min per stat. Need a way to measure?

25 Overcooling Troubleshooting  Inspect the vent line for excess leakage. –Quick check is to plug the line and cap #4 fitting. –Install check ball. –ACERT engines have two vent lines. This will require an update to the vent line recommendation. Current line configuration is above the fitting for the check ball.  Truck Engine News 1999/04/01 Media Number -SEBD Publication Date -New Cooling System Vent Line Check Valve Helps Prevent Over Cooling{1370}  Know Your Cooling System; SEBD0518 (paper)  Know Your Track-Type Tractor Cooling System; REHS1063

26 Overcooling Troubleshooting  Investigate thermostat or thermostat seal leakage. –Several methods used to test. –1) Historically, thermostats were checked with a hot plate and thermometer. It has since become economical to replace them if removed. Note: this test gives thermostat performance not leak rate. –2) Recently the increased use of infared temperature instruments to estimate leakage of the thermostats. The results are qestionable. (40% of thermostats replaced are no fault found.) –3) Measure the leakage rate and compare to known specifications. More accurate with results that can be documented. Criteria with this test is pass or fail. Less invasive and conclusive. –P/N 7C3095 = 2 x 10cc/min max leakage. Opening Temp degF –P/N 7W0317 = 2 x 50cc/min max leakage. Opening Temp degF –Fabricate tool to measure volume change. Accurate method and gives good results. Todd and Doug to show an example tool that was fabricated.
