Help

[PEU]

I have a cub cadet Sc2400 3cyl yanmar diesel with 50hrs. When it warms up(about 10 mins).The rpms drop, shakes with blue white smoke and stalls.Can someone help.

open the fuel cap.. is there a return to tank fuel line and flow?

is there a restricotr indicator on the air filter?

[Don87]

Is the fuel gelling up? Have you treated your fuel with anti-gel?

Are your fluid levels correct.It sounds like either water of oil may be entering the cylinders or the injectors are putting in too much diesel and stallimg the engine.Maybe someone more knowledgable will chime in. With only 50 hours is this a warranty/dealer issue?

or the injectors are putting in too much diesel and stallimg the engine.

what?

remember.. a diesel is a fuel driven air pump.

more fuel - more rpm till it blows up.

intake is straight pipe..

that's why diesels runaway around gas line leaks.

overfueling might lead to lots of smoke and washed walls and increased wear and reduction of lube properties of oil via dilution.. but they don't gurgle out like a flooded gasser...

Blue-white smoke sounds kinda'like an air inleakage or something leaned out your fuel mix as it warmed up? Just a thought. don-ohio (:^)

[Soundguy]

blue can be oil.

white can be water or unburnt fuel ( black is unburnt fuel )

leaned out fuel mix? have you ever worked ona diesel before?

they are open throat intakes..

fuel injected determines rpm.

no such nomenclature of lean....

a diesel engine is a fuel driven air pump

your coments sound like you are thinking about a GAS engine

Noooooooo,SG! I am talking about an air inleakage pure and simple,and with these more fancy riggin's these days,who's to say they don't play with the injection mix? White is what air inleakage looks like.I know...I been there....suffered that! don-ohio (:^)

P.S.; I'll be magnanimous and pretend you never said that. You don't own a 10 ton backhoe for 20 years and NOT have worked on a diesel,SG!LOL!

[Soundguy]

saying lean on a diesel forum gets you looked at funny.

Maybe you wonder why truckers want their fuel turned up RICHER? don-ohio (:^)
