Engine Repower

I think you would be hard pressed to convince a cop along side the road that you are ELD or emissions exempt in a 2015 truck with a 99 engine. No matter if legal.

 

If you are talking about man '97 engine in a 2001, that would not be an issue. But a 2015 with the same engine, well won't fly.

 

Yes but there are a couple catches, the first the epa rule supersedes the fmcsa, the fmcsa doesn’t deal with emissions regulations.

The second is the state is the actual one who enforces these regulations and like the fmcsa refs being used as the states, the same goes for epa even in California.

So the same issue arises.

When you put a 1998 engine in a 2010, it is not legal.

One other thing that many don’t seem to understand is how gliders work, the title for the truck used to go with the drive train because the serial of the engine was recorded as the prime identifier, but now they issue titles for the gliders as I see from a few in my records as assembled vehicles with a non-state vin (acceptable) being used as the prime identifier. It was explained to me how it all worked some time in the 60’s by my uncle who had a large fleet. The reason for gliders in the first place was to allow an owner to use the same power unit and drive train with a new cab and chassis, then it became a tax thing in the late 50’s. This allowed someone to use a dependable setup without going through the problems or expanse of a new unit, a lot of engines never saw more than 200k on them before a complete rebuild.

 

2003 is the year we would have to use, that was when EGR systems were going on the trucks. The EPA has listed engines from 1998 to date as part of their emission reduction program with 2007 and 2010 listed as major checkpoints in the program.

I know that one truck I owned a while back was ok with the state, it was a 2002 with a '96 engine in it, mainly because it wasn't considered an emission engine. So 2003 and newer.

 

Just talked to custom truck and they are getting in new Pete's with Cummings engines removing them and repowering with 1999 cats and state it is 100 ,% legal as long as they are not buying the truck. The owner brings the truck to them.

 

There’s a shop here in SLC that’s been installing old Cats in late model Cummins powered trucks.
