hopefully not the original belt
I tore it apart this weekend and found a pretty new looking belt - With the hours it has that's a very good sign!
Maybe 4 times is a charm. Keep loosing what I write.
Sorry that did not come out right. (weird due to injector clearance being out) should say "run weird due to injectors failing and internal clearances being out".
And to expand upon that The crank shaft can be spinning in worn bearings and moving up and down, worn bearings can cause low oil pressure and increased internal heat, cam lobes can loose metal off the lobes and cause valves to open incorrectly, the piston can gall the cylinder walls and cause the motor to smoke and burn oil. And so on..
I have friend that is a mechanic and he says he does not want someone elses junk... he wants to know exactly how something has been used and he does not want to work on problems created by others. He calls contractors the worst.
I buy used equipment and so far I have been lucky and bought great used machines. I normally check the function and load test the machine to make sure power from engine and hydraulics seems right so that has helped me avoid getting something that is completely shot.
A question I have that I could use more understanding on from you guys is the gray area between runs good and complete failure due to an overheat. Say a extreme overheat has happened, metal in filter, engine misses a little till warm or all the time, more than normal noise in the engine. I was told during an overheat the water turns to steam and cooks an engine from the top down. Is that a true statement? What is causing the noise - is it valves burnt or opening an closing incorrectly, are the rockers going out, does cooked oil ruin everything it touches etc? What will happen if you change the oil, pour lucas in and keep using it. Assuming it still has some oil pressure, can the engine live on and still make money or is it still likely to have a major part failure once an extreme overheat has occured? Does the heat ruin the mechanical injectors? I am not talking about then most modern diesel engines but the slightly older diesels from the late 80s / 90s and early 2000s
Again, I'm not sure if the engine has been overheated or anything.
I'll be long winded here for a minute. So I bought this thing out of the south west side of Arizona. I'm from Colorado. (830 miles / 12hours) I had long conversations with the owner about the machine and he reassured me about the condition of the machine (Bought it from a dealer)
8 hours into the trip I blew an injection line on the truck and continued to drive for the next 4 hours until I got there.
After seeing every bushing on the machine worn out and the engine loping, I didn't want to buy the machine. I was livid, but he had a truck I could use the injection line off of. I literally bought this skid steer so I could make it back home.
I've replaced every bushing in it, and am now trying to get it to run right so I can sell it as a solid machine.
So this weekend I set the valve lash and pulled the timing belt cover off. After the valve lash, the engine definitely sounded much quieter, but it didn't help the lope. There is a pretty new looking belt under the cover, so that's a big plus.
There is an external screw near the governor that the book calls "Speed governor with minus adjustment" - turning that either did nothing
There is also a screw under the timing cover called the "Idling Capsule" - turning this in raised the idle, and screwing it out lowered the idle.
I did get around to replacing all of the fuel lines as well - That didn't do anything.
Any advice on where to go from here??
