Diesel tractor belching black smoke


My little 3 cylinder diesel tractor is sick - low on power and laying down a black cloud of smoke that will kill off 2 generations of 'skeeters back in the woods (and probably me too). I tried to mulch some leaves and it hardly had enough power to turn the mower deck on high speed as well as pull itself. My guess is that the fuel injectors are crapped up or just plain worn out. I found a place in Indiana that will supply them - but at $133 each, seems a bit expensive, especially since the gas fuel injectors for my truck are only about $28 each!!! Anyone know of a shop that used to sell Bolens tractors with the ISEKI 15/17 Hp diesel engine that might still have some stock left? I haven't pulled one out yet, but suspect that they are nothing special and are probably used on 50 other tractors - just like the common $8 NGK glow plugs that it uses.

Oh yeah - the lawn - never had so many acorns and leaves as this year:



I took 25 wheel barrow loads of acorns alone to the woods in the first raking and then started using an 8x17 tarp - and took 15 or so more along with 50% of the leaves  with the other 50% coming down last night in a heavy rain/wind so I'll be back to the rake and leaf blower tomorrow and Thursday.

I'm not a diesel guy.. but do know that cold weather, fuel contamation. water in the fuel. all cause the problems you are having

 go here to maybe get a idea of what might be wrong,, Like leaking injectors..and a cloged air filter

Thanks for that article BR. It made me think - air filter possibly and I'll give it a check in the morning. Might just be that another dam' chipmunk crawled in the inlet hose and made a nest. I've cleaned a couple off the side of the engine already this year including one petrified/over cooked carcass and that's about when the problem began .... only hope it's that simple. Then, of course, there's that ultra low suphur diesel fuel. The engine starts easily so maybebiggrin

Running super rich.  Just like in a gas engine, look for something that is either reducing the air intake, or squirting too much fuel into the cylinder(s).  Since it starts easily, and probably is idling ok, air filter would be my first thing to look at, then the fuel pressure regulator, and the injectors.

If it was running good when last used,, I would say air intake obstruction,, dead chippendale, critter.. or the fuel has waxed up .. run some injector cleaner through it ...or a little kerosene.. with the fuel

Thanks for the replies, especially that article, BR

I pulled the air filter apart this morning and quite frankly, have no idea how that little engine even started and kept running. That chamber was almost totally filled with bird seed as well as two chipmunk bodies, well done of course. Then the stench of overdone 'meat'.......getting a bit ripe. The filter was cleaned as well as possible, but I do need to find a replacement as well as a fuel filter.









I do have to post on a couple other forums as well, just for chuckles.

Busy little critters aren't they?  we have problems with Squirrels around here,, but surely not to that extent,, Must not have had any emergency excape plan in effect , in case of unexpected engine start,, sizzle sizzle,, roasted chipmonk yummy,, just gotta get it while its fresh off the grillnobiggrin

with all those accorns,, no wonder they are thriving,

I had some seats out of a car, stored in the shed,, and the rats got in them and built a retirement home out of all the stuffing,, nothing but bare springs left,,

Glad you found the problem.. no expensive injectors needed,headbang.gifheadbang.gif

omg.gif  Yep, that'd probably do it, or at least be the major contributor to the problem.
