PTO clutch





First off here is the rest of the electrical test boards that you have assigned. Also I found this site really helpfull when I was learning how diodes work, ( http://electronics.stackexchange.com/questions/54977/how-does-a-diode-work.  I think that it is really cool that they work like a check valve and only let current flow in one direction. At work I have been told to figure out why a PTO will not work properley on a 4240. I started by checking the hydraulic oil and I found that it was black and reaked of burned clutch material.  So I decided I needed to split the tractor to check out the PTO clutch and the evidence is in the picture above.  It was fried.

electrical



This week I have been working through the electrical test boards and have completed all that have been set up.  I also completed the twenty five question online pre test that was asigned to us. At work I have rebuilt a hydraulic cylinder.  I have also split two tractors for a clutch replacement and to rapair a transmition. I also tracked down why four work lights on a tractor had quit working.
