3406B leak question

looks like one of my 3406b

 

Yeah, Cat owners think they have gold..... but a B model is obsolete as of now. No way to get a mechanical engine through emissions.

I just don't recall B's being yellow cept in equipment. 16's were, 31's were, 36's were but the 34's I saw were white ( in trucks ) ....... JMO maybe I need to get out more often...

 

in 33 years ,i never saw a cat that filthy...

 

Truck I drive is a 1995 KW with a yellow 3406. All the trucks I have driven that had 3406's in them were yellow.

 

I believe the white 3406's were a Paccar thing, and only the A's & early B's (7fb's) were painted white until mid to upper 80's when they started painting them yellow, maybe the 4mg, and have remained yellow ever since.

 

Early 3406, commonly called the "A" model.
