What Is The Hardest Working Part Of A Diesel Engine?

[Doc Tinker]

To simplify this a little, let's narrow the question down to our 5. 9 Cummins.



What single part of our engines do you think does the most work? Why do you think that?



Doc

 

[Texas Diesel]

Doc, where do you get these questions???

I'd have to say the #6 cylinder because it runs the hottest.

 

[illflem]

The injection pump because of the high pressures involved.

You thought I was going to say the spark plugs right?

 

[CTabor]

The crankshaft every thing goes through it .

 

[JTBMC]

Us of course, doing all the maintaince to keep ourselves happy

TJ

 

[Evan A. Beck]

Well, I think it is going to be either the injection pump, crank, or even the starter.

 

[bighammer]

Let me guess... . the TURBO, cause it's always whining the most?

 

[MOWPAR]

The lift pump seems to get tired before everything else...



Jim

 

[David Oxland]

camshaft lobe

exhaust valve seat

 

[LSMITH]

LOL@bighammer and jjwitt!!!!!!!!!

 

[HDH]

I say its the Pistons, Because there is so much Bombing around here. .

Doug.

 

[HEYBOSS]

The owner, he has to work his a** off to pay it off and even more to bomb it

 

[LarryB]

After a little research I'd have to say the Rasamatonic Rebaflexor.

 

[KB0OU]

THROTTLE CABLE

IT HAS TO PUT UP WITH ME AND TELL THE WHOLE ENGINE WHAT TO DO

Doc... . It has to be the lift pump on a 24V as they seem to wear out the quickest.....

 

[Jeff H]

What would we do without those motor mounts?

Is this a test? Ahhh I hate tests

The hardest working, well it doesnt move.



For endurance your #6 lower bearing.

The loads on your crankshaft are a walk in the park for it,

remember its forged steel and 120 lbs in weight!



Next probably your engine block!

 

[TxDieselKid]

why do you want to know...?

I would say that it is the fuel/lift pump, out of any year.



Or maybe the glow plugs. .

Upper rod bearing and lower crank bearing ... . in all engines!
