Electricity

This week in class we performed some electrical test on the FLD. First we tested the alternator output. The rated output was 140 amps at 2k pens. We couldn't get past 83. Didn't know if we didn't have everything on or what but it never reached the rated output. Next we tested how much volts it put out. Around 14.8volts. That's about all we did and ate pizza of course.

Srt4 and a FLD

This week in class our group did some test on the FLD. We tested the battery strength with a carbon pile tester and did some volt readings. In our other class we worked on my personal Srt4 neon. For some odd reason the fans were not working. We performed a bidirectional test with no luck. We then removed the fans and supplied power to them via the battery and they worked. Turned out to be a bad connection in the plug on the fans. We cleaned up the wires and boom! Fans now.

Electrical training

This week in class we went over the basics of electrical circuity and put our radiators back in.

Radiator and Toyota

This week in class we had 2 guess speakers from Toyota come in and talk to the class. They described what it takes to be a master tech in the Multiverse of Toyota.We also began taking the radiator out of the Hino truck. Very interesting finds with the A/C system. It was way overfilled from the factory. And also antifreeze likes to go everywhere.

Finishing the Aveo and FLD

This week in class we found the J1939 connector on the FLD. We also took the coolant temp sensor out and tested it. We took a lighter to it and watched as the resistance went down as the temp went up on the sensor. After that we put it back in the series 60. Don't forget the pipe dope and to plug the connector back in. In the other class we removed the thermostat out of the Aveo. First time i have seen that type of thermostat. It was weird!! then we tested it with a pan of water and a cutting torch. We recorded the data at the opening temp and closing temp. After that we put it back together and filled it with coolant.

ECMs and Thermostats

Why in the world is the drain plug for the radiator on a 2010 Chevy Aveo LT located at the very bottom on the side. Not just in a annoying place but behind some A/C lines and sits right behind the core support. So after fitting your hand into space about three inches wide you then have to put a 13mm wrench on it to break it loose. Well after that struggle the radiator can be trained and the thermostat can be removed from its housing. Make sure to spray down the bolts on the housing. Hate when manufacturers connect aluminum parts to cast iron parts with aluminum bolts. Welcome to snap city! ECMs oh the good and hard to find ECMs. You figure they would be mounted inside the cab or another location where they wouldn't be exposed to the elements. But nope not on a 1191 Freightliner FLD. Right inside the frame is where you can find it, covered with dirt and grease. Along side labeling the sensors and outputs, finding the J1939 wires can be a challenge in the dirt and grease. But my team and I did.

The basics of HVAC and electronic engine controls by Jacob Williams

This week in class we started on the basics of HVAC learning and electronic engine controls. During the engine control class we had to fine the ecu and label some important sensors. Unfortunately the ecu was not in the location we thought it was and we were not able to get on the computer to locate it before class ended. In the HVAC class my team and I worked on a 2010 Chevy Aveo Lt. We performed a leak test on the cooling system but did not realize we had to use the leak test dye so we still have to perform that. We also tested the pH level of the coolant and made sure the radiator cap relieved pressure at the right psi. The radiator cap was weird on this cat because it wasn't actually on the radiator but on the reservoir tank. Next week we get to finish our test and continue on our mission of greatness.

This week is pizza week!

This week in class my group and I worked on getting the international and freightliner running. We then went to take the injectors out of a 6.0l ford with some missing parts.

The Day That Could...

This week in class I was not there,. I woke up with a stomach problem and spent most of the day in bed doing homework

This week

This week in my first class my group and I inspected our turbo on the N14. We checked for cracks on the flange, manifold, and housing. Next week we hope to check shaft end play and reinstall it. MY second class my partner and I did a write up on the DD15 labeled some parts on the rig . That's all! And drilled some bolts out.

Midterms

This week in class we took midterms. After midterms we went to go take a test to see what are strengths are and worked on a LSX Signature 600. The test wasn't working right so most of the class couldn't do it. And this test is something I don't believe, test are not a good way to prove someones strengths. After that class my group and I worked on LSX 600 hundred. After checking all the fuel system components we found out it had air in the system. We bled the air out of the system. NO PICTURES BECAUSE WE WERE WORKING.

Jake Brake check on a Cat

This week in class my group and I started working on a Cat C-12. The C-12 is on a stand and has everthing to make it run icluding the computer which we have to figure out why it isnt reading right. We didnt have very much time on it so this week we are getting down and dirty with it.

It Runs!!!

This week on WSCC Diesel Family my classmate and I get the N14 running. After last weeks episode we decide to redo the over head on the N14. My classmate and I set the overhead on all of the valves we messed with. It was time consuming but we got it done and it runs!

N14 overhead set and CAC testing

This week in class was a adventure. In my first class on Monday my group and I did a CAC (Charge Air Cooler) test. To do this test we had  to disconnect the CAC from the turbo and intake then fit a OTC tester to one side and block off the other. We hooked a air supply to the test and regulated how much air going into the CAC (about 35psi) After we set the pressure to 35 psi, we shutoff the air and timed how fast the pressure dropped.(15 seconds) For the system to pass it could not drop 5 psi within 15 seconds. Which it did pass! We learned that the system can hold a lot more than 35 psi(had it up to 50) with out it failing. The test is really simple to perform.

Moving onto my second class we had to set the valve clearance on the N14. Everything was going smooth until we realized ( after the motor wouldn't turn over) that we didn't have the push tubes and rockers seated properly.  We fixed that then found out that we were doing the intake valves,instead of the exhaust valves. We are still currently working on it this week.

N14 Injector Removal

This week in class my group and I worked on a N14 Cummins. I have always liked the N14 because it reminds me of a old 12-valve Cummins, really simple to work on and simple mechanics. This class period we had to take three of the injectors out. We started by shutting off the power to the truck by switching the battery disconnect to the off location. I really find the disconnect interesting and thinking about getting one for my car. After that, a team member and I started disassembling the valve cover. First we removed the bolts then we had to remove the engine brake assembly for each part of the valve train. After finding the right socket, it was apparently hard to find a 7/16 12-point socket so it took longer to remove those but we finally did. Then it was onto the rocker assembly. We first removed the bolts and with a little motivation and some paint markers to remember where they came from we finally got those out. Lastly, it was time to remove the the injectors. We removed the injector retaining clip and used a crows foot to "pop" the injectors out. 

So, what I learned is that the N14 is a real simple design and the correct procedures in how to remove its injector. 

Installing thermostat and fuel filter.

After removing the thermostat and making sure it worked properly by heating water with a torch and watching it open we had to install it back on the truck. After installing the thermostat into the housing we bolted everything down to specs and used a neat little tool to refill the cooling system. We used a tool that plugged the coolant reservoir then used shop air to create a vacuum pulling the coolant out of the containers and into the coolant reservoir. After we found the leaks of course. After refilling the coolant we checked for leaks and everything was good. That ended the first class of the day. The second class was fuel systems. In this class we replaced the fuel filter and primed it on a  series 60. We also looked at our new Snap-on tool we got and let me tell you that diagnosis

machine is crazy. It can read everything the computer sees.

Learning Begins

This blog is for both of my classes with Starkey. This week in class we learned how to take a fuel tranfer pump off using our service literature and remove the thermostat. Sorry no pictures

New beginnings

Welcome to the new year of school. This class is going to be a blast. Diesel tune up and Maintenance. This week in class was just introducing everyone and getting settled in. Have some pictures of the. We year.

Finals week

As my group and I continue to assemble the ISX we have another challenge upon us...Finals!! This week is our last week of school but more importantly it is the finals week. Some finals I am ready for, others like English I am still not sure about. Hopefully I do well in them all, and so does everyone else.

Another week, another mission

This week my group and I got everything ready on the ISX to do the overhead.
