Cat engine model year

It is certified as EPA 1999. Goes by build date.

 

I know we have gone through this before, but just to reiterate, my 6NZ has a build date of 12/23/99, in a 2000 KW, with an emissions sticker conforming to 99 emissions standard.

 

I'm in the same boat with my 2WS @Oxbow .

From what I've read, so you're in good shape as far as exemption.

Who was the fella here that was talking about the 60 series Detroit built in 99, but was stickered for 2000 emission standards? That's what has gotten kinda confusing on this deal.

 

I stay confused on this deal I think.

 

At least I am pretty sure my 89s with the B models are in the clear!!

 

Me too.

 

See that's the camp I'm in, it's a good feeling too

 

The whole thing is about clear as mud! This is what FMSCA says...

If the vehicle registration for a commercial motor


vehicle reflect a model year of 2000 or newer,

but the engine plate or documentation from the

manufacturer indicates that the engine is older

than model year 2000, is the vehicle exempt from

the ELD rule?

Yes. While an ELD may voluntarily be used in vehicles that are model year 1999 or older,

use of an ELD is not required in these vehicles; likewise, vehicles with engines predating

model year 2000 are to be treated as exempt, even if the VIN number reported on the

registration indicates that the CMV is a later model year. When a vehicle is registered, the

model year should follow the criteria established by the National Highway Traffic Safety

Administration (NHTSA). There may be instances where the model year reflected on the

vehicle registration is not the same as the engine model year, most commonly when a

vehicle is rebuilt using a “glider kit.” In this circumstance, an inspector/investigator should

use the model year on the engine to determine if the driver is exempt from the ELD

requirements. If the engine model year is older than 2000, the driver is not subject to the

ELD rule. While the driver is not required to possess documentation that confirms the vehicle

engine model year, 49 CFR Part 379 Appendix A requires motor carriers to maintain all

documentation on motor and engine changes at the principle place of business. If a

determination cannot be made at the roadside, safety official should refer the case for

further investigation.

Not sure about Detroit or Cummins, but Cat if it was built in 1999 ( last date of 6NZ was 12/23/99, they labeled it as a 1999 model year. Some were even dyno tested in 2000, but labeled as 99 model year. They were 4,943 6NZ's built in 1999. Bet the value of them went up! I know @Oxbow has one. I might play on Quickserve and see how Cummins labeled them and I guess I can fool around DDSN if I get a chance
