Can someone elighten me to what differentiates the 1, 2, 3rd generation trucks? What defines them the year or type of motor? Can someone also break it down for me?

thanks Jamie

Here's a good description and source for info.

Those are all nice looking trucks - but especially that middle one...

Nice truck phox!!

Engine-wise, the 1st gens had the 12V Cummins 6bt with e Bosch VE rotary pump. It can vary timing.

In 1994 the change was made to a 12V Cummins 6bt with the Bosch P7100 inline pump. This is the big pump putting out the huge smoke for the pullers and such. But it cannot vary timing. Factory HP rating varied from the same as the 1st gens all the way up to 215hp.

Halfway through the 1998MY, they switched to the the new 24V Cummins ISB with the Bosch VP44 electronic injection pump. It can vary timing quite a bit. HP increased to 235. IN 2001, a High Output model stepped up power to 245/505 with a slightly different version of the VP44 pump.

in 2003, the change was made to the new Bosch HPCR (high pressure common rail) design. This setup gives ultimate flexibility for engine management of timing and fueling. They also now had pilot injection, which made them quiet.

Halfway through the 2004 MY (just like they did with the 1998 trucks) they changed AGAIN to a newer version of the HPCR, which had even more power.

So, the CTD has gone from 160hp/400tq to 325hp/610 tq in just 15 years. That's over DOUBLE the power.

So am I to understand that:

1st gen = up to 1993

2nd gen = 1994-1998

3rd gen = 1998.5-present

Thanks Jamie

Almost. 2nd gen is '94 - '02, 3rd gen is '03 and up. The engine changed in '98, but the truck stayed mostly the same.

Generally the "gen" refers to the body style more than the engine.

1998 was a year of change.
It gave us the "Quad Cab" with rearward opening doors as well as the 24 valve engine, but the body style didn't change until 2003 (2002 for the 1500's).

2003 was the biggest change.
Not only a new body style with 4 doors, but a new frame as well as a totally new fuel injection system.
The 1500's got the new body and frame in the 2002 model year,
2500's and 2500's didn't get it till 2003 model year.

I know it's diesels here so it's a given the 2500 and 3500s started the 3rd gen in 03, but the 1500s started their 3rd gen in 02.

You could forego the quad cab in '98. I was able to order mine strictly as an ext. cab without the suicide doors.

phox_mulder

Right, but 98 was the year it was introduced.

I'm confused, what about 12valve@heart's website he posted. Those numbers are different than what is being said here.

Pretty sure the generations referred to there are the motors changes, not the trucks changes.

1st generation would be 12 valve with the VE-pump,

2nd generation would be 12 valve with the P-pump,

3rd generation would be 24 valve with the VP-44 pump,

he doesn't even address the 24 valve with the common rail injection
(what we refer to as 3rd generation)
