the CM2250 Volcano ...

[Rawze]

The SCR system is well known to act up in the CM2250 and CM2350 engines. One of the big causes is the buildup of dried DEF fluid in the SCR dosing pipe. here is what the outside of the SCR pipe looks like...




Here is one that I saw today inside this same pipe I have circled in the above picture -- It was almost completely blocked on the inside of it ...





This guy had been to the dealer for low power, boost problems, Aftertreatment issues etc. etc.etc. -- they changed turbo and all kinds of expensive stuff... Repeatedly --- And they accused his DPF of being bad and cleaned it. Then they wanted to rape him for another $4500 for a new SCR can. ... He was at the end of his rope with it... so he took it to Mr. Hags shop .... All that was wrong with it was a leaky SCR Doser injector, clogging up his exhaust pipe almost completely. he also had an exhaust manifold gasket leak that was making for lower than normal boost too.

That is what you get when you go to the truck dealer to have your truck fixed. -- Everything but what should actually take place --- Actual troubleshooting!.
