Buyer guide
- Cat's 320D/320D L reference pairs the C6.4 ACERT with ADEM A4 electronic management. Check the supplied ECM, harness and fuel-control arrangement against the machine.
- The cited 320D installation lists 103 kW net flywheel power and Tier 2/Stage II equivalent emissions. Treat these as one machine reference and match the replacement by engine plate and arrangement.
- Cat's 320D installation uses automatic engine speed control. A bare replacement assembly may need the machine's existing electronics and accessories, so confirm the supplied components.
Buying questions
What electronic control does Cat document with the C6.4 in a 320D?
The cited 320D/320D L brochure identifies ADEM A4 engine management. Confirm the ECM and wiring supplied with the offered assembly.
Can the 320D's 103 kW rating be assumed for every C6.4 ACERT?
No. That figure is the cited 320D/320D L net flywheel rating; the replacement must be checked against its own engine data plate and machine arrangement.
