Caterpillar Engine Serial Lookup

Thank you so much! Excuse my ignorance. If I have the number correct, it should be in a Pete. So am I to assume this was a FL build? I see some that can check via the last six of the vin. 556725. It surely looks original to me, but you never know I guess. Can you or someone check by the vin please?

 

I don't have that ability. I think some of the other guys can access the dealer systems.

 

Recheck your number, 556725 came with 6NZ30420.

 

Thank you!

 

Okay- lets try this again. 6NZ30420 Looking to buy so any history would be great. Thank you in advance.

 

Hey guys can anyone get some more info on 6NZ58959?? I just bought a 2013 glider with this engine in it. I believe it’s rated at 355hp now - sticker missing on engine. It just got new injectors before I picked it up - 10r-0956. The turbo p/n is 176-7716. Just wondering if it was rebuilt with the same internals as the higher hp engines. Thank you!

 

Can someone tell me when my CAT 6NZ11699 was built? The tag is partially missing. Thanks!

I found out that the 6NZ I thought I is not actually what is in my truck. Haven't found the stamped numbers on the block yet, but thinking it is 5EK34320. Anyone care to run it and see what it may be?
