Safety is key

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. this is a warning label from aldata Pressure/velocity related injury to the index finger estimated at between 100-1,000 lbs/sq.in.  i looked up some more on the lethal strike video and on the web and saw this pressure warning but i think its being nice you could several injury at even lower psi

way way over 300 hours for work and right on track for school

I took a fuel presser test from the fuel filter and manafold, both read 65 psi.smthing i learned over the weekend is a blinker light just because it has three wires comming off it and has a cool flash took it doesnt need all three wires hooked up. I took about a half hour rewiring this blinker nice and neat. the wiring was all green and didnt work. i asked the driver to try his blinker and yes it blinked like the other side but what i didnt know is that three wire set up is so if you wanted the blinkers to act as running lights for the front. what i wired up was running slash blinkers for the rear. Thats  illigal

Thats a shock

 This is the valve cover on the 7.3 in the shop at school. I took the cover off because iv never seen wires integrated into a gasket before. Don't poke holes in wires you could get shocked says the manufacture.

The glow plugs take alot of current to run them.

Schooling in Motion

 plastic gauge it came in within specification the tolerance the kobota book called for were .0007 to .0020 and we measured .0015

 upon disassembling this motor we found no rings. one thing i can take from this motor dissembly is i know the names for the parts allot better and there locations on the motors. another piece of information i learned it the 4 Cly are a shaky motor due to being only a 4. one thing kobota did to stop this is add weight balancers ran off an idler gear.

this is a corroded battery i found at work on a service i did. just tells you always check every thing when servicing machiniory

kubota

30 hours of work last week and 12 hours of school

Today my group and i started the disassemblly on the kubota 3300 diesel motor. I noticed it doesn't take  long to get in a chest deep out of order dirty mess when disassembling a motor. We got the head off and were into the tops of the pistons in a totals of 20 Min's. but something i saw others doing is taking card board and labeling it then sticking there parts into for a tidy little package.

Caution Learning in Progress

 This is a capture on the modis for the blower motor on the black dodge. the blower motor has a resistor box. the box gives the motor less resitanc as the switch is turned up.

The picture here is of a little dc motor we built in class.

Diagrams and Schematics

Some things I've learned at school have helped me in my life.  For example:  we had to wire up a switch for hazards, left turn signal and right turn signal.  Some guys and I stumbled around for about 45 minutes, trying to figure out how to wire the switch.  Our instructor then gave us the wiring diagram.  We proceeded with the wiring and it was done in no time.  If you don't succeed the first time, read the directions!  Another example:  A student brought in a car to have her door lock switch fixed.  I was test probing around locking doors, unlocking doors, not knowing what I was doing.  I then printed out the schematic and found the car runs off relays, switching grounds to make the doors lock and unlock.  So what I've learned is wiring, diagrams and schematics can be your friend.
