1528 smoking issue

[double e]

My 1528 is only a year old, but it has always blown ALOT of black smoke on start up even in the summer months. I called my dealer and he said that it was normal and to try starting with the throttle about a 1/4 open, this did not work. I exspect a little smoke, but when I start it in the garrage(a large 2 car with 14'ceilings it instanly fills it with black smoke. If this is normal than I can live with this, but if not I would definetly like to find the problem. Any ideals would be greatly appriciated.

The smoke is due to incomplete combustion until the glow plugs heat if so equipped.

Is that ok,or should I have it looked at.

Do u give the glow plugs time to heat before u try starting it. I've noticed they all smoke some on start up but not that bad.

My 1531 smokes real bad on startup hot or cold

Yes, usally hold the key for 7-14 sec depending on how cold it is, but in the garage it never gets below 40.

What are you using for fuel? Do you have a block heater? I would probably recommend heating the plugs a little longer. I know that my 1528 needs longer to warm up than some of my other tractors.

My 1532 is garage kept too, smokes bad on start-up like the rest of yours.
Using the block heater for 2 hrs will helps. You have to get ready to move it outside the garage and leave the doors open for a while.

My old BX 25 only puffs a little white smoke when cold starting in the winter.

Takes a while to get used to all of that black smoke, my dealer claims it is normal too? ( 55 hrs only on it)

I have a 1532 that I bought new a couple of months ago , and it does the same thing . I keep mine inside too . I usually hold glow plugs on a few seconds release and repeat a couple of times , my salesman said that is how he does his personal one . This is really the only concern of the tractor I have had . Not wishing you bad luck , but am glad to know someone else is experiencing this . I may contact MF hotline tommorrow , maybe if we all do this issue , might become important to them .

While, I don't like all the black smoke, it is a relief that it just may be normal for them and not actually something wrong.The smoke is not a big deal in the warmer seasons for I just leave the garage doors open for a while, but when it is 20* and the garage is heated and I have to open the doors . I guess I will have to put it in the lean to next winter when I am done building it

G'day whilst i do not know your model the following is applicable to all diesels -black smoke is excess fuel usually seen whilst revving up or under load or can also appear with a blocked air filter - white smoke is unburnt fuel caused by incomplete combustion i.e. lack of pre heating, dribbly injectors ( too much fuel in cyl) or low compression. What you are encountering is probably the injector pump going into excess fuel for start up on most machines this is done manually ( full throttle, push/pull button/lever on pump) but on some it is done automatically, this is just a starting aid and if it seems common across the range then it is prob nothing to worry about. Hope this helps

I keep my 1529 in a garage also. Mine would blow a big puff of black smoke on a cold start even after 30 seconds of glow charge before turning the engine over to crank. After having the engine block heater installed, the smoke is not an issue. It starts quick and idles smooth. I had a New Holland TC29D before the MF and it blew black smoke also. I assume its normal.:thumbsup:

Many of the small diesels will use an thermostatic swtich that is mounted in the cooling system, that when in the open position (cold engine), changes the injection timing and can cause the puff of smoke at startup. Altering injection timing is done to help the engine warm up.
Once the coolant reaches a high enough temp to close the switch... it sends a signal to the injection pump and the timing is changed to the operating temp. setting. THis may be why some have stated that after installing a block heater, the symptoms seem to disappear.
Who is the engine manufacturer that builds the MF engine?..

Iseki.

Did the Cat Challenger branded tractors also have this same engine?

The temperature switch makes sence. Could you bypass it to see the difference in start up. ?

What is everyone running for fuel? I know mine didn't act well with heating oil so I switched back to pump diesel.

 

[double e]

I am running regular pump diesel and off road diesel does not seem to matter.

 

[Dakota_male]

I run as well pump diesel, but add Power Service, Diesel Fuel Supplement with cetane booster in it. ( 4 oz/ 4.5 gals)

It would depend on whether its a normally closed or normally open switch. This system has been used on Perkins for years and more recently the small Perkapillar diesels...
I'm sure it can be bypassed, but you would NOT want to leave it that way due to excessive fuel dilution in the oil from the timing being altered.
