Overview of the Detroit Series 60 Engine Belt System
The Detroit Series 60 engine is a popular diesel engine used in trucks, buses, and industrial applications. Its belt system is designed to drive essential accessories such as the alternator, power steering pump, air conditioning compressor, and water pump. The belt routing is optimized for efficiency and durability, but it requires regular inspection and maintenance to prevent failures.
Key components driven by the belt include:
- Alternator
- Power Steering Pump
- Air Conditioning Compressor
- Water Pump
- Idler and Tensioner Pulleys
Understanding the layout and function of these components is vital for correct belt installation and replacement.

Understanding the Belt Diagram Components
Primary Components
- Serpentine Belt: The main belt that loops around multiple pulleys, driving various accessories simultaneously.
- Idler Pulley: Guides and maintains tension on the belt, ensuring proper contact with pulleys.
- Tensioner Pulley: Keeps the belt tight and compensates for belt stretch over time.
- Crankshaft Pulley: The primary drive pulley connected to the engine crankshaft.
- Accessory Pulleys: Pulleys attached to the alternator, A/C compressor, and power steering pump.
Additional Components in the Belt Path
- Water Pump Pulley: Typically driven by the serpentine belt to circulate coolant.
- Auxiliary Pulleys: May include idler pulleys to route the belt around tight spaces or multiple accessories.

Typical Detroit Series 60 Belt Diagram Layout
The belt routing diagram varies slightly depending on the engine model year and specific configuration, but the general layout follows a standard pattern.
Basic Belt Route:
1. The belt starts at the crankshaft pulley.
2. It loops around the tensioner pulley.
3. Then proceeds to the water pump pulley.
4. Moves to the alternator pulley.
5. Passes through the A/C compressor pulley.
6. Returns to the crankshaft pulley, completing the loop.
Visual Guide:
- The serpentine belt forms a continuous loop.
- The tensioner pulley maintains proper tension.
- The belt crosses over and under pulleys following a specific sequence for optimal contact.

Step-by-Step Guide to the Detroit Series 60 Belt Diagram
Tools and Materials Needed
- Correct replacement serpentine belt
- Socket set and wrenches
- Belt tensioner tool or breaker bar
- Gloves and safety glasses
Procedure for Belt Replacement
1. Ensure Safety: Turn off the engine, remove the key, and disconnect the battery to prevent accidental startup.
2. Locate the Belt and Pulleys: Identify the belt routing diagram specific to your engine model.
3. Release Tension: Use the belt tensioner tool to relieve tension on the belt. Carefully move the tensioner pulley to create slack.
4. Remove the Belt: Slide the belt off the pulleys, noting the routing or referring to the diagram.
5. Inspect Pulleys and Tensioner: Check for wear, cracks, or damage.
6. Install the New Belt: Route the new belt according to the diagram, ensuring it sits properly in all pulley grooves.
7. Apply Tension: Use the tensioner tool to apply tension until the belt is snug.
8. Final Check: Rotate the engine manually or run it briefly to observe the belt's movement and ensure proper alignment.
9. Reconnect Battery and Test: Reconnect the battery and start the engine to verify correct operation.

Tips for Maintaining the Belt System
Maintaining your Detroit Series 60 belt system ensures longevity and optimal engine performance. Here are some essential tips:
- Regular Inspection: Check belts for cracks, fraying, glazing, or missing chunks every 10,000 miles or during routine service.
- Proper Tension: Ensure the belt tensioner maintains correct tension; too loose causes slipping, too tight causes bearing wear.
- Clean Pulleys: Remove dirt, oil, or debris from pulleys to prevent belt slippage.
- Replace at Recommended Intervals: Typically, belts should be replaced every 60,000 to 100,000 miles or as specified by the manufacturer.
- Monitor Belt Noise: Squealing or chirping sounds may indicate misalignment or worn belts.

Troubleshooting Common Belt Issues
Issue 1: Belt Slipping or Squealing
- Likely caused by loose tension or worn-out belt.
- Solution: Adjust tensioner or replace the belt.
Issue 2: Cracks or Fraying
- Indicates aging or damage.
- Solution: Replace the belt immediately to prevent failure.
Issue 3: Belt Misalignment
- Caused by pulley wear or improper installation.
- Solution: Inspect pulleys, realign or replace damaged pulleys, and reinstall the belt correctly.
Issue 4: Overheating or Water Pump Failure
- A slipping or broken belt can cause water pump failure, leading to engine overheating.
- Solution: Check the belt and water pump pulley system.
