I have a cat 312 that I bought a little over a year ago to use around the farm.
It is a 1994 model and has 5400 hours on it.
I have put about 200 hours on it with not problems so far. NO leaks, runs cool, starts easily, good power, walks true.
I changed the engine oil as soon as I bought it but nothing else.
All the work I have done so far was in cool weather, today was the first day of work in hot July south Georgia weather.
(1) The HYd oil temp got very close to the red line so I shut things down after about 3 hours of work.
What should I look for as the most likely cause of the hyd oil getting hot?
(2) A very small leak sprang forth dripping from the left side belly pan. I removed both of the left side inspection covers to expose all the small hoses that run up to the hand controls and it looks like this leak might be from the left joystick.
I have no idea how to get at the hoses under the arm consoles.
How do I get to where the hoses connect to the joystick?
(3) there is also a small hose that looks like a vacuum hose that is not connected to anything but has a hose couple on the end.
Can anyone tell me what this hose connects to? I could not see anything for it to hook to.
(4) The control pad is faded and I really do not know what all the buttons control.
Can someone clue me in on what these buttons control?
THanks in advance.
