Title: 440D kicking smoke
Post by: Offthebeatenpath on March 08, 2014, 08:12:18 AM
I know this question will show my ignorance- I'm new to skidders and far from a mechanic,  but my 1985 440D just started kicking gray smoke.  It's worst when idling- there are faint pops like little bongo drums when it's at a low idle. 

I cleaned the air filters, threw in some fuel additive and new good fuel, checked the air to turbo line for oil- it's dry. Engine is newly rebuilt.

Injection pump out of time?  Can I work it another week or so and deal with this during mud season?

I had a rented 540d on a job that started doing that and within 2 hrs the turbo let go.Cost 1k to get it fixed and I did the mech.

For sure keep a eye on turbo, It will start leaking around the seals and then when she goes its ovious, Been getting alot of moisture in the fuel with all this weather, My 440c likes its fuel filters changed alot, I sure hope its simple and not turbo, If so, They are a pretty easy on and off fix, I got mine at PB&H equipment in Antrim NH. Good luck

Dang.  If you were closer I'd look at it for you.  It might just be an injector.

Appreciate the offer.  Where are you at?

I talked to a mechanic today, Check your injectors as other fellow said, They for sure can be the problem, I always keep tank about half full with the 440c, When I first bought it 6 years ago I had lots of smoke and alot of problems with filters and I replaced 2 fuel pumps first winter I ran it, After that it all cleared up in this 440c, Been 5 plus years and still no smoke and if I keep changing filters about every 4 months it really seems to help. Hope its that simple.

grey or white smoke is incomplete combustion. could be an injector over fueling ( not misting the fuel ) that could wash the cylinder of oil not letting the rings seal. or broken rings. have you ever either locked it starting it??? an infrared temp gun works good for checking exhaust temp for each cylinder. to inspect the turbo pull the air intake hose off and push pull the turbine also up an down also look for cracks. if the turbine comes unraveled its gonna go into the engine

I agree start with the fuel filters. But it does kinda sound like a bad injector

Could pull the injectors and have them checked. I had mine done in bangor and ended up with 4 new ones.

Sounds like you have a dead cylinder. It could me something as simple as an injector opening prematurely. Find out which cyl. is giving you the trouble. If you don't have a heat gun, as previously mentioned, just crack each line to find the miss. Do it at idle, one at a time. Each good cyl. will cause a big drop in rpm, the bad one will give little or no drop. This is a little messy but will give you a starting point.

isn't it better to put all new injectors in it   one new with 3 old  ???

 Injectors for a 276-T are maybe 50-70 each. Whats going to take you time is when you pull the fuel piping, figure you might as well add new rubbers while your there. Check your oil, ive seen injectors run wide before they completely die. Had 10 gallons of fuel mixed in with 5 gallons of oil, wondered why it shook and didnt wanna run right ....?  8)

Thanks for all the help guys.  Should be enough troubleshooting to keep me busy for a good chunk of my Sunday...

If you crack the injectors ,make sure you dont get to close to the nut with bare skin,you dont want a fuel injection thru your skin. !!!!

How did ya make out with the 440d smoke problem
Title: Re: 440D kicking smoke
Post by: Offthebeatenpath on March 13, 2014, 06:33:15 AM
Got my last load of sawlogs and pulp out with it still running rough.  Going to play with firewood for a few days until my mechanic has some free time to check it out with me.  Thanks for asking.

Should have known the Forestry Forum collective knowledge is rarely wrong. Diagnosis- faulty injector with only a couple hundred hours on it.

Should be good to go by lunchtime on Monday after a quick trip to Diesel Fuel Systems in Bangor...

Glad it was only an injector. Beats a complete rebuild that I had to do. Diesel fuel systems seem to know their stuff. Pete helped me out when I was having motor issues.

Diesel fuel systems is a top notch company.

Do you recall the cost to check? I called them and the guy I spoke
to didn't seem to really know what he was talking about and said it'd be probably $100 or so to check 1!!
Title: Re: 440D kicking smoke
Post by: Offthebeatenpath on April 16, 2019, 12:10:08 AM
I honestly don't remember the cost but I think it was under $100 to check.
