Applications & fitment
Documented application references

Buyer guide
- Cat's cited C9 ACERT source describes an industrial power unit with radiator, flywheel, alternator and wiring. An engine-assembly listing may have a different scope, so request a component list.
- That C9 ACERT power-unit reference uses HEUI injection, ADEM A4 control and an SAE No. 1 flywheel housing. Match the machine's fuel, electronic and drivetrain interfaces.
- The C9 ACERT reference covers more than one rating and emissions combination. Use the actual engine plate rather than carrying over the power-unit rating to a replacement assembly.
Buying questions
Does the C9 power-unit brochure prove a radiator and alternator come with this engine assembly?
No. Cat describes those parts in its complete industrial power unit. Request the actual assembly's parts list to see what is included.
Which injection system is listed for the cited C9 ACERT power unit?
Cat lists HEUI injection, with ADEM A4 electronic control and an SAE No. 1 flywheel housing. Verify the offered engine's generation and build.
