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.
