Caterpillar Engine Serial Lookup

Not sure if this is the info you want but here is a parts list for your particular engine.

I'm thinking you want to know hard parts it was built with and horsepower and torque rating? That I don't know but sure someone will chime in on that.

 

It says that it is a 3406E, 355 HP @ 1800 RPM, was in a Peterbilt. Build date of 12/22/95, ship date of 01/04/96. I am kind of new with the SIS system, but hopefully this is correct. It gives me all the individual part numbers as well if you need anything.

 

Built date: 22Dec1995
Ship date: 04Jan1996
3406E / C15

HP 355 @ 1,800 RPM

Original turbo part number looks to be 130-6233 or a 130-9107. CAT numbers are weird.

 

No, I'm not sure, and after looking at your tag I would think the that would be the information to use. I just quoted what SIS said.

 

I'm not sure what size or how that turbo flows but looks like part number 0R-7136. You can look at your turbo that is currently on your engine and there should be a tag on it.

The hp rating on your engine when shipped from factory was 355. It could of been uprated by now, I think the only way to find out what it is currently set at is to hook up to a computer.

That data sticker you showed is something they put on every engine showing year it was produced and engine serial number. Max hp on that engine can go to 550 hp@ 1800 rpm, is how I am reading it but I could be wrong.
