What kind of shaft is in a Cummins diesel?
What kind of shaft is in a Cummins diesel?
This twisted input shaft came out of a 48RE automatic tasked with handling more than 1,500 lb-ft of torque being dished out by the 5.9L Cummins in front of it. With that said, input and output shaft failures aren’t typically as catastrophic as intermediate failures.
Which is the first heavy truck Cummins Engine?
The 15-litre Cummins was the first heavy truck diesel engine with electronics and dual overhead cams as integral parts of its innovative design. The dual overhead cam design allowed Cummins engineers to optimise engine and braking power. The Gen II version was released in 2003 to improve reliability and durability.
What causes a Cummins diesel engine to fail?
When the top compression ring worked itself loose from the number two piston inside a 5.9L common-rail Cummins, this was the end result. This type of failure is proof that anything can happen, at any power level, and even in Cummins mills, which are hands down the most reliable and durable power plants you’ll find in the diesel pickup segment.
What are the shortcomings of a Cummins Engine?
1. Killer Dowel Pin (KDP) Due to its ability to completely trash an engine, the killer dowel pin tops our list of Cummins shortcomings. On the assembly line, a tiny steel dowel pin was pressed into the block of ’89 to ’02 mills in order to locate the engine’s timing gear housing.
What are the most common problems with a Cummins transmission?
Some of the most common problems with this transmission involve being stuck in a gear, failure of the torque converter to lock, or hard shifts. These problems are known to make successful mods to this transmission nearly impossible. That is largely due to the small size of the transmission’s shafts, clutches,…

What happens when an input and output shaft fails?
With that said, input and output shaft failures aren’t typically as catastrophic as intermediate failures. When an intermediate goes, it distributes shrapnel throughout the rest of the transmission (fluid, clutches, gears, pump, torque converter), which usually means the only salvageable component is the transmission case.
Why is the Cummins 47RE transmission so small?
That is largely due to the small size of the transmission’s shafts, clutches, and converter; they’re all considerably smaller than those on the competing GM (Allison) and Ford Super Duty transmissions. The 47RE also uses an older design on its components that existed before the transmission was introduced.
