Detroit Diesel Series 60 Cylinder Head: A Comprehensive Overview

The Detroit Diesel Series 60 engine is renowned for its durability and longevity, and a crucial component contributing to its performance is the cylinder head. The cylinder head, or “head” as it’s commonly called, houses the valves, injectors, and coolant passages, playing a pivotal role in the combustion process and overall engine health. Understanding its features and maintenance is key for anyone working with these engines.

What is the Detroit Diesel Series 60 Cylinder Head?

The cylinder head of a Detroit Diesel Series 60 engine is a complex casting typically made of cast iron or aluminum (depending on the specific model and year). It’s bolted to the top of the engine block, sealing the cylinders and creating the combustion chamber. The head contains precisely machined passages for intake air, exhaust gases, fuel injection, and coolant circulation. The proper functioning of the valves, injectors, and their respective mechanisms is entirely dependent on the cylinder head being in good working condition.

Key Components Housed Within the Cylinder Head:

• Valves: Intake and exhaust valves control the flow of air into and out of the cylinders.
• Injectors: Injectors precisely meter and spray fuel into the combustion chamber.
• Valve Seats and Guides: These components ensure proper valve sealing and alignment.
• Coolant Passages: These channels circulate coolant to regulate the head’s temperature, preventing overheating.
• Rocker Arms and Bridges: These transfer motion from the camshaft to the valves.

Common Issues and Maintenance

Like any engine component, the cylinder head is susceptible to wear and tear over time. Common issues include cracks (often due to overheating), warped surfaces (also caused by overheating), and worn valve seats and guides. Regular maintenance, including proper coolant levels, timely valve adjustments, and addressing any signs of overheating immediately, can significantly extend the life of the cylinder head. Over time, wear can compromise the cylinder head‘s ability to seal properly, leading to loss of compression and reduced engine performance.

Upgrading and Remanufacturing

When a cylinder head fails, there are several options: replacement with a new head, installation of a remanufactured head, or rebuilding the existing head. Remanufactured heads are often a cost-effective option, offering similar performance to a new head at a lower price. Upgrades, such as improved valve springs or porting (modifying the intake and exhaust passages), can enhance engine performance, but should be done with careful consideration of the overall engine design.

Frequently Asked Questions

1. How often should I inspect my Detroit Series 60 cylinder head?

A visual inspection should be part of regular maintenance, every 250,000 miles or during an overhaul, with closer attention paid if you notice unusual engine performance such as loss of power or coolant consumption.

2. What are the symptoms of a cracked cylinder head?

Symptoms include coolant leaks, overheating, white smoke from the exhaust, and coolant mixing with engine oil.

3. Can a warped cylinder head be repaired?

Yes, a warped cylinder head can often be resurfaced by a machine shop to restore its flatness. However, if the warpage is excessive, replacement might be necessary.

4. What causes a Detroit Series 60 cylinder head to crack?

Overheating is the most common cause. Other factors include improper installation, excessive cylinder pressure, and defects in the casting.

5. Are there different types of cylinder heads for the Detroit Series 60?

Yes, there are variations based on engine model, year, and application. Some heads are designed for higher performance or specific fuel systems.

Summary

The Detroit Diesel Series 60 cylinder head is a critical component of this powerful engine. Proper maintenance, prompt attention to potential issues, and informed decisions regarding repair or replacement will ensure long-term reliability and optimal engine performance. Understanding its role and potential problems is key for owners and mechanics alike.
