My KAMA developed a cold

[GRUMPA]

Well, went to the ranch on friday to take up another load of stuff and decided to get some seat time in. Ran like a champ for about 3 hrs moving dirt piles the back-hoe left behind when I did my footers. About 3 hrs into moving dirt with the FEL all of a sudden I heard a funny sound like one of the cylinders wasen't working right. I looked at the exhaust and it was coming out kinda white. So here I am in the middle of no-where wondering what to do.

So in the house I go and dig out my manuals for the thing. No easy task since I'm moving and everything is in boxes. Well about the only thing I can figure is I got a bad injector, don't really know how or why I only got 52 hrs on it. At times like these I really wish they give you a book on the engine it's kinda hit and miss without one.

Back outside I go and start her up and when it starts up I get a belch of black smoke and same thing. When I raise the RPM's it spits out white smoke, when I lower the RPM's I get black smoke. But that sound is still there, the sound of a mis-fired cylinder. Bad injector? Don't think its the injector pump there's just not that many hours on it. And how do you find out which one is the bad one? Is there some sort of fool proof way? or is it a hit and miss deal?

Anyway since I had the dirt removed I figure I would use the BB and smooth things out. Just then the wife came out to look at my handy work. I got off the tractor when I parked it and she pointed to the rear of it wondering what that thing was hanging from the rear of the tractor. I looked and I'll be, the right hand screw rod sub-assembly was broken off at the lower link. Darn of all the luck, I hope this dosen't happen to be a repeat performance. Living rural has its pluses, and as I'm finding out it's minuses as well.

To find out which injector/cylinder is acting up, with the engine idling, crack the line at each injector. the one that does not change the engine sound when the line is loosened is the bad one.

also check to make sure the valves are not out of adjustment. Possible that you have lost clearence in one and holding a valve open.

 

[GRUMPA]

That would be a likely possibility. But without a book on the engine, I wouldn't know the technique or the valve clearance. Guess I'll call my dealer today and find out.

Sorry to hear about your bad luck, but then that's the way my luck runs all the time. I had the same thing happen to my 354, seems to have dropped a cylinder and lots of white smoke. I don't know if yours has a compression release for starting, but that was the problem on mine. I moved it several times really hard, started her up and all was fine. Just a thought. /forums/images/graemlins/grin.gif

Mine dosen't have a compression release on it. Those engines have what they call direct injection on them. I really don't know, since they did that they no longer need to have compression releases on them /forums/images/graemlins/confused.gif. The white smoke was easy to see but with 30mph+ winds it's kinda hard to see how much white smoke I was getting.

Grumpa ... Direct injection engines still have a compression release. My KM454 has one ... its a black knob lower left on the control panel ... engine kill is to the right. I doubt the configuration on your TS is the same but I'd guess there is a compression release somewhere...Scozz

My KAMA 395 is direct injection and HAS a working decompression system. Your engine might be direct injection, but I believe it does in fact have compression release. If so, you'll find the exterior connection point on the aft end of the valve cover. More likely, you just don't have the compression release linkage between that point and the operator position.

If true, you still need to at least remove the valve cover and observe all valves going through a full open/close cycle.

But if you haven't noticed water in the oil, you'll probably find in the end that it's simply a dirty/failed injector or injector supply.

You know what? After going thru my book your right. It shows a compression release. Thing is my books are with me right now in the city and my tractor is at the ranch 5hrs away. To be honest I never realized it had one thanks for pointing that out. Normally when it was sitting on the side of my house I started it up every other month just to get it warmed up and it started up faster than both of my trucks so it didn't even occur to me.
