Forged crank? and fuel guage

[Bluebird]

1. Do our Cummins 5. 9's have a forged crankshaft? Saw the Tundra commerical where they brag/demonstrate the weight their crankshaft can hold. Yeah sure:-{}, can it pull like a CTD:-laf?



2. My fuel guage has just started to wonder around after fill-ups. I continue to average 21+ mpg, (does the Tundra get that kind of average mpg) the gauge just does not go all the way past the full line like it used to???



Thanks y'all, this forum is the best. I learn something new every time I log on. Yes sir, I am a proud CTD First Gen. owner/driver.

Tundra commerical where they brag/demonstrate the weight their crankshaft can hold.

Near where I used to work someone had a crankshaft as a mailbox post. It had a small mailbox mounted on it so I guess that was a Tundra crankshaft.



During the last year of my CTD ownership, the fuel gage started to take several minutes to a half hour to register full. I don't know what changed unless I had an iffy ground connection or some corroded wire. That did not affect mileage

Forged, not forged?

I continue to wonder how the crankshaft is constructed Just looking for more stuff to brag about...

According to the 2003 Dodge sales consultant guide, under the driveline section, page 13,
yes the Cummins has a Forged Steel Crankshaft.

First Gen crank?

I wonder if this applies to ten years earlier in the First Gen engine?

It's forged. A cast one would not hold up well in our application. You would be reading about failures.

It's Forged. According to the Cummins B series manual I have, Published in '87.

REAL engines use forged steel cranks.
