Understanding Schedule D

What Are Schedule D Tasks?

Schedule D tasks represent the most comprehensive level of preventive maintenance in light duty intervals, focusing on major component overhauls, replacements, and system rebuilds to extend vehicle life.

These tasks are typically performed at extended mileage or time intervals, addressing wear from prolonged use in light duty applications. They integrate with Schedule A tasks, Schedule B tasks, and Schedule C tasks for complete PM coverage.

Frequently Asked Questions

Common Questions About Schedule D Tasks

Answers to key questions about implementing Schedule D overhauls in light duty PM plans

Schedule D tasks are typically triggered at major milestones like 100,000-150,000 miles or 5,000-7,500 hours, depending on vehicle type and usage. Refer to our calendar trigger table for time-based scheduling.

Unlike routine checks in Schedule A or intermediate services in Schedule B, Schedule D involves complete system rebuilds and major component replacements.

Costs range from $5,000-15,000 per vehicle depending on scope, but yield ROI through extended life and avoided breakdowns. Compare with severe duty frequency adjustments for variations.

Yes, our mixed fleet policy allows customization of Schedule D tasks across different vehicle types while maintaining consistency.

Specialized tools including engine hoists, transmission jacks, diagnostic scanners, and torque tools are required. Training on these aligns with light duty frequency guidelines.

Proper execution and documentation of Schedule D tasks ensures vehicles exceed DOT safety standards, reducing inspection failures and fines.
