Black Smoke followed by sudden death?

Soundguy · Mar 19, 2008

Oh I agree.. good point.. if it is a huge ridge.. it's well worn.. etc.

I like the idea on the hydro pump.. a locked pump that is deadheaded would be alot to push against.. but I think the pump mighta failed by now???

who knows.. it's as good a theory as any.. especially the timing gear issue..

Just thinking out loud , is the timing gear on the camshaft keyed on or is it pressed on ? I wonder if the cam timing has been checked . Worked on an M.A.N Diesel truck motor that had a pressed on gear , had the same kind of symptoms . The gear slipped 5 degrees on the shaft and killed the engine , can't remeber if it was belching black or white smoke . Soundguy// . I have a "Wirth" ridge remover that works a treat but i was meaning if it has a large lip in the the bore it will indicate it's too far oversize for a re ring as it will make the new ring gaps to wide . Which will prevent compression coming up too specs . It's about a hundred years since i knew this stuff well but 3thou per inch of bore is ideal , would that be correct ?

The mech brought up the siezed hydro pump concept, but next I talked with him he was asking about shims for the injectors. I don't think it's anything like that because when I go to move the tractor, I'll raise the loader and TPH by turning the engine over with the starter.

I've been so busy this week and I'll be pretty busy next week too. I still haven't gotten the tractor home.

She's not dead yet!

A guy I work with has a friend who knows somebody who he thinks can probably get it running.

I figure, "What can I lose".

I told the guy I work with that if he can get the thing fixed, he can use it whenever he wants.

I think the tractor was just lonely and she waited until I bought her a friend to really start trying again.

It never fails that a missing part turns up after you install the replacement!

My cyber fingers are crossed!

It may be that it's spring now and guys are more likely to want to work on something... I've got guys coming out of the woodwork now suggesting that they can fix this tractor.

Actually what I have is guys coming out of the woodwork suggesting that they have a friend who can fix the tractor. I had an acquaintence stop by tonight as I was grading the driveway with the new Massey. He said he's got a friend who says it has to either be timing or valves.

I guess if the friend of the guy I work with can't do it, I can send it off to this other guy.

Look how many options I have now.

Friend of a friend... might just work out for ya... Lotsa times a 2nd or 3rd or 4th set of eyes sees what one doesn't..

If anybody is still out there--the answer to this man's problem may be a broken crankshaft. I know it sounds crazy. I've only seen it once but the machine operated similiarly to what has been described here. When started the motor would idle but when accelerated would load up and die out. It had no power and smoked black smoke at higher RPMs. The owner wanted the clutch brake replaced. He thought the clutch brake was coming on when at higher RPM's. What was actually happening was as the RPM was increased the one half of the crankshaft was trying to move ahead of the other. since the break was not smooth it was forcing the shaft ends apart and putting pressure on the main bearing webs. When the engine was stopped for a while the ends of the shafts moved back to origianal position.To test drop the oil pan and remove the main bearing caps one at a time --always replacing the previous cap before removing the next. If I am correct the break will be a main bearing journal.

Thanks for the input. I'll have to keep that in mind if the current strategy doesn't pay out. My symptoms are a little different in that it doesn't even go in low RPM.

Right now the friend that took the tractor to fix it has come full circle, and he's now back to where I left off... "How in the $#%@ do you check the timing?"

I realize I'm gettin' in late on this discussion, but I'd get the tractor back and pull the head. A blown gasket between the cylinders makes compression low on both cylinders and it doesn't take alot of comp. to fire ether, I'm still amazed it would not hit on ether. I had one of these tractors few years ago TX1500 Iseki 4x4, I really liked it just smaller than what I needed.
