Kenworth 10,000-Mile Service Maintenance Checklist
Introduction
The 10,000-mile service interval is a critical maintenance milestone for Kenworth trucks, marking a comprehensive service point that helps ensure continued reliability, efficiency, and longevity of your investment. This structured maintenance service addresses key components that require regular attention based on the manufacturer's recommendations and real-world operational needs.
This detailed checklist covers all essential maintenance tasks for Kenworth trucks at the 10,000-mile interval, encompassing engine systems, drivetrain components, chassis and suspension elements, brake systems, and more. Consistently performing these maintenance procedures at the specified mileage interval helps prevent unexpected breakdowns, reduces overall operating costs, and maintains optimal performance across all Kenworth truck models.
Vehicle Information
10,000-Mile Service Best Practices
- Service Interval Adjustment: While 10,000 miles is the standard interval, adjust based on operating conditions. Severe service applications (frequent stops, extreme temperatures, dusty environments) may require more frequent servicing at 5,000-7,000 miles.
- Fluid Analysis Program: Implement oil and fluid analysis during each 10,000-mile service. This predictive maintenance tool can identify internal issues before they cause failures and potentially extend service intervals when appropriate.
- Service Documentation: Maintain detailed digital records of each 10,000-mile service, including all fluid types, quantities, filter part numbers, and observations. This documentation is essential for warranty claims and resale value.
- Component Rotation: Consider strategic component rotation strategies for components like tires to ensure even wear and maximum service life across regular 10,000-mile service intervals.

Detailed Service Procedures
Follow these step-by-step procedures for critical 10,000-mile service tasks:
Engine Oil & Filter Change
- Run engine to operating temperature, then shut down
- Position oil drain pan under drain plug
- Remove drain plug and drain oil completely (15-20 min)
- Replace drain plug with new gasket
- Remove old oil filter using appropriate filter wrench
- Clean filter mounting base, ensuring gasket is removed
- Apply thin film of oil to new filter gasket
- Install new filter hand-tight plus 3/4 turn
- Fill with proper grade and quantity of engine oil
- Start engine and check for leaks
- Shut down engine, wait 15 minutes, recheck oil level
Fuel Filter Replacement
- Shut off engine and set parking brake
- Place drain pan under fuel filters
- Disconnect water-in-fuel sensor electrical connector
- Drain fuel from filter housing using drain valve
- Remove primary filter by turning counterclockwise
- Remove secondary filter using same method
- Clean filter mounting heads
- Apply clean diesel fuel to new filter seals
- Install new filters until seal contacts base
- Tighten primary filter 3/4 turn after seal contact
- Tighten secondary filter 3/4 turn after seal contact
- Reconnect water-in-fuel sensor connector
- Prime fuel system using hand primer or starter
Air Brake System Service
- Check air compressor drive belt tension
- Drain all air tanks by pulling drain cords
- Inspect tanks for excessive moisture or contamination
- Check air dryer operation and purge valve
- Verify governor cut-in (approximately 100 psi)
- Verify governor cut-out (approximately 125 psi)
- Perform leak-down test (max 2 psi/minute)
- Check application pressure at service chambers
- Lubricate slack adjusters and S-cam bushings
- Measure push rod travel at 90-100 psi application
- Verify low air pressure warning at 60-65 psi
- Test spring brake activation at 20-40 psi
Chassis Lubrication Service
- Locate all chassis lubrication points
- Clean all grease fittings before lubricating
- Use proper grade chassis grease (NLGI #2)
- Lubricate steering drag link and tie rods
- Grease king pins and thrust bearings
- Lubricate spring pins and shackles
- Grease clutch cross shaft (if manual)
