Engine/Transmission (1998.5 - 2002) What are the Cummins, trans and axle weights?

[Chris N5CWM]

I'm researching how much the individual components weigh,

the 24 Valve ISB, NV4500, NV5600, Dana 60 front axles and

Dana 70 & 80 rear axles.



What sparked my curiosity? Had a weigh-in with a new GMC

2500HD at the dragstrip scales, and both trucks were within

100 Lbs of each other. Both are 3/4 ton extended cab short

bed 4x4's. The GMC has the DMax/Allison and mine has an

NV4500, Dana 60 front & 80 rear axle. Both trucks have the

factory aluminum wheels.



There are a few posts over at the GM site (thedieselpage.com)

about thin roof and bed sheetmetal, which makes me think GM

is trying to get the overall weight of the truck down so their

load carrying capacity numbers look better than the competition.



The roof of my Ram does flex a little when had washing the truck

but the bed is very stout, never flexes a bit. Seems the GM bed

can be dented just grabbing onto the bedrail and pressing on

it with your palms!



I'm wondering if the DMax is as light as it's aluminum heads

would make it. The Allison weighs about 330 Lbs.

Chris,



According to the 2001 Product Guide, the Cummins dry engine weight is 942 lbs.



I have seen another chart that listed the standard Cummins as 1020 lbs. , and the HO at 1103 lbs. Never could figure out why the difference, but that's what the chart said. Also showed the NV4500 at 200 lbs. and the NV5600 at 350 lbs. No axles shown.



The problem with these (and most numbers that might get published) is what do they include? Accessory drive, flywheel, bellhousing, clutch, brake assemblies, fluids, etc. Hope this helps - still leaves a lot of guesswork.
