Hydraulics

Today in class I leanred a little bit about hydraulics. And when I went to work I had the chance to work hands on with some hydraulics. I worked on a rolled over forklift. Here are some pictures....



My assignment was to take off the cab. Which means I had to disconnect all the hydraulic fittings going to the controls to use the forks on the forklift. In class I leanred a lot about saftey measures that I need to consider while working with hydraulics. I leanred that if the fluid gets shot into your skin and you don't go to the doctors quick you can start to say bye to some fingers maybe even a hand. Here is a picture of my work....




 
If you notice I used colored zip ties to make sure I know where all the hoses go if I need to reinstall them. Then I bleed out all the fluid into a pan. From this I leanred about safety when working with hydraulics and how to distinguish which line goes where by color coding, and then a good way to empty out the lines. In the last picture you can notice I also cut the coolant hoses and I drained all the coolant into a pan. 

After I was done with my part of the project I was told to put new brakes on a trailer. Here is a picture...


I put on new brake shoes and a drum. Then adjusted the slacks on both sides of the axle so that the slack is at 1.25 inches.

Beginning electrical

This week I leanred a lot about open HRVD and short electrical problems that can occur. Using electrical boards and hands on experience I leanred how to distinguish open or short circuit problems. On the back of a truck the right brake light was not working there was a short in the system. I fixed the light by replacing it and the problem was resolved. 

I did this practice quiz here are my answers





Then this week I redecked a flat bed. My hole drilling skills that I leanred in class came in handy. Here is a picture of what I did...
