HST-3 ???

I mis read the external egr part seems all 5740's have it

My guess is yours is a -1 like mine maybe your engine sn can be deciphered to find out if its a V2403-M-TE3-HST. I believe the TE3 would make it a -3

Just my thougthts

Anybody have more insight? My local dealer can't even tell what I have.:confused2::confused2:

I don't know about the cab models but if your's is an open station you could have a -2. I was told very few were made. Your dealer should be able to take your SN and use it to order the correct parts for you.
