Can somebody walk me through the process for removing the engine from a Case 444 graden tractor?
I recently worked on the carbueretor , and I got the engine running -- briefly.
It ran on high idle for about twenty seconds, and before I could turn the key off, it stopped - I mean stopped abruptly.
I thought that meant something seized up, but the pulley turns freely. I don't think my departed Father-in-L:aw was big on engine maintenance, and it is doubtful if anybody bothered changing the oil in this thing before I came along.
Now, I'd like to remove the engine from the tractor; then, I'd either take the engine to somebody for work, or more likely, I'd take a look at it myself. Can somebody walk me through the process of removing the engine, so I don't screw anything up?
It looks like the engine sits on two frame rails, with two large bolts on each side.
What about removing the doo-hickey on the front, that controls the belt for the mower deck? How does that come off?
What about disconnecting the engine from the hydraulic pump?
Looks like there's a couple of 1/2" bolts in there, and clearance looks tight, so it's definitely for a good crescent wrench.
Anything unique I need to be aware of?
How about removing the muffler?
I don't have any air impact tools, but I think I may need something like that -- or at least, a torch.
As for the engine itself, the things I suspect are: broken connecting rod, bent valve push rod, etc.
It's broken already, so I don't think I can break it any worse than it already is.
I've torn down and replaced basic components in engines once or twice before, so I feel I can at least look it over -- and then take it to a pro, if necessary.
Thanks for any/all advice on this matter.
