What to do if your Duramax crankshaft is weak?
What to do if your Duramax crankshaft is weak?
The ultimate fix for the weak factory crankshaft is to replace it with a stronger unit that’s been internally balanced. The billet Callies crankshaft available through Wagler Competition Products is machined from triple heat treated 4330V steel and features reduced rod journal widths for improved strength (which calls for narrower rods).
What causes the injector on a Duramax to fail?
The two primary failure points of the factory injectors are internal cracking of the injector body itself and corrosion-induced failure of the internal ball seat. The solenoid style Bosch units found in the LB7 employed a non-hardened internal ball seat to seal the injector.
Are there any flaws in the Cummins Duramax?
Still, and just as we exposed the shortcomings of the almighty Cummins, the Duramax isn’t without its flaws—some of them catastrophic. For example, did you know the injection pump on the LML version is prone to coming apart and wrecking the entire high-pressure fuel system when it does?
Are there any problems with the Duramax engine?
The failure is most common in higher horsepower engines, but can still occur in moderately modified and even stock power plants. Not specific to one version of Duramax in particular (ex: LB7, LLY, LBZ, LMM or LML), the problem exists across all generations.
What makes the Duramax 6600 diesel so good?
The foundation for the Duramax 6600 diesel’s superior performance is its cast-iron engine block. The block was developed using computer-based Finite Element Analysis, which optimized its balance of strength and weight.
What kind of connecting rod does a Duramax have?
We’ll be honest, experiencing a tweaked connecting rod in an LB7 Duramax (’01-‘04) or LLY Duramax (’04.5-’05.5) is almost exclusively reserved for engines making double the factory horsepower (or more).
Is there a tuning option for a Duramax?
As most duramax owners have only one vehicle the SOTF duramax tuning option is top notch. The ability to change the usability of the truck at a moments notice will make this type of tuning on of the most popular.
