Went to start the dozer today and it sat for 3-4 weeks. Some one was messing with it, throttle lever was at full throttle, bucket was off the stack and batteries are just about dead. One of our guys try starting it not aware of any water problems.It turned over quite a few revs, smoked and ran out of juice. We know theres water in a cylinder, its been spun over a several times but most of the time it was very slow because of dieing battery. I drained about 10 oz out of the exhaust manifold by lossening it. What are the chances that a push rod went? Im gonna pull the injectors and suck the rest of the water out so we dont loose it to rust. Any other easy things to help me with? I cant tear the motor down where its sitting unfortunately, i need to get it running quick and easyily as possible. So if anyone might have so good news it would help alot? Ive been told all kinds of bad stuff allready.
Well, what make and model is the crawler? Secondly did you get water out of the engine or antifreeze out of the engine. It was setting outside with the bucket off the stack right?
Its a mid 80s 84-86 forget. dresser td 7e. Water is from rain or some one pouring it in the stack. I got a bunch out but ran out of time and tools because of location.
If it spun over, then I would not think there is water in the cylinder. If there was, it would start to crank, then come up hard and stay there. Sounds to me like you have a muffler full of water, but not much else to worry about except a dead battery.
No muffler straight pipe. I know for a fact one cylinder had water in it or still does.
if the engine turned over, then you didnt hydraulic the engine. recharge the batteries and it should fire up.
The water would have gone to the lowest sitting part of the manifold first and filled that cylinder (assuming the ex. valve was open), then filled the cylinders in an uphill order. What you are worried about is hydrolock. Water is not a compressable fluid, if one of the cylinders was mostly filled and at BDC ON COMPRESSION STROKE, then you might have heard a bang if you HAD started it....but you didn't. Probably lucky the battery was dead. Charge the batteries, and turn it over on the starter many times (shut off fuel) to blow it out the exaust and you will be okay.
If it's hydro-locked, pull the injectors out and crank it over with a wrench till the water is blown out. Reinstall the injectors. Drain the crankcase, check for water in engine oil. If water is present, flush engine with a bit of diesel fuel, change filter, install new oil and attempt to start. Operate till engine is warmed up, then change oil and filter again. May have to do this a couple more times to work moisture out. Even then, the engine may take several hours of running before drying out internally. Suggest you invest in an elbow or exhaust flapper. If engine turns over now, just change oil and filter and run. May have to do as above if water is present in crankcase however. You might consider performing an oil sample soon. Good Luck!
Well i took the injectors out this mourning spun her over easy and threw out about 2 cups of water. Sprayed some areokriol in each one while it sat till i put it all back together. started up just fine in about 4 revolutions. Sounded just like it always did. My only other question now. When i poped out the injectors there was no oring on them but there is a grove, and theres no indication of any orings being in there at all. @ of the bores were so clean it was like a mirror so i no there wasnt any ring in there. Is there suposed to be? I didnt notice it leaking at all but i didnt get to spend much more time there, after i ran it for 15 minutes and had to leave. Saturday im gonna runn it good and change the oil and put the covers back on.
It's been some time since I was in the smaller IH diesel engines. But as I recall, there is no O-ring on the nozzles. The heat would quickly fry them. KOO might remember for sure.
when i forget to put a rain bucket over top of the stacks on any of my straight piped 8's...... i just give em a sniff of nose candy while trying to fire them. they blow that water out like nothing to it
Im gonna put a flapper on it now, so it hopefully dont happen any more.
