Known issues on the 2020 LCF 4500XD. Both federal columns are empty for this year — no recalls, no complaints. Routine diesel service is what the manual is for, and its detail is the reason to reach for it rather than for a general guide. Mechanical procedures for the engine come with published clearances; the fuel, turbocharging and cooling systems come with specifications; the driveline and chassis come with torque values for both bodies; and cab faults come with wiring diagrams.
