Applications & fitment
Documented application references
- Cat Parts lists a 3412 engine assembly, part 131-4877, for a 773D truck; this is an application example, not fitment for this listing.
Application examples identify documented uses of the engine family. Confirm fitment against the machine and engine serial numbers before ordering.
Confirm your engine match
- Request the included-component list and test record for this assembly.
- Provide the existing engine serial and arrangement plus the machine PIN. Compare mounts, flywheel housing, cooling and fuel systems, electronics, accessories and emissions configuration.

For fitment checks, availability or a quote, email info@nyengines.com with your engine data-plate photo, machine details and required assembly scope.
Buyer guide
- A 3412 family label does not identify the exact generation. Cat's 3412C generator-engine reference describes a V12 with pump-and-lines fueling; check the supplied plate before using those details.
- Clarify the assembly scope. Cat Parts separately shows a 3412 complete engine, a 3412E reman long block and a reman short block; these are different packages.
- For generator duty, the cited Cat 3412C package operates at 1,500 rpm for 50 Hz service. This generator specification cannot establish the rating or equipment of a bare 3412 replacement assembly.
Buying questions
Does '3412 engine assembly' tell me whether it is a complete engine or a long block?
No. Cat Parts lists those as separate 3412-family packages. Request the supplied component list and exact arrangement.
Can a 3412C generator-set rating be used for any 3412 replacement?
No. Cat's 3412C page describes a particular 50 Hz generator package. Match the offered engine's generation, rating and application from its plate.
