Dec 31, 2018


Welcome to Grafco Electric, your trusted source for all things related to diesel engines. In this educational guide, we will delve into the topic of diesel engine camshaft inspection and provide you with comprehensive information about detecting and addressing adverse wear.

Understanding the Camshaft

The camshaft is a critical component of a diesel engine's valve train system. It plays a vital role in regulating the opening and closing of the engine's intake and exhaust valves. Over time, the camshaft can experience wear and tear due to various factors, such as inadequate lubrication, contaminants, or excessive engine load. To ensure the optimal performance of your diesel engine, regular inspection and maintenance of the camshaft are essential.

Signs of Adverse Wear

Identifying signs of adverse wear on a diesel engine camshaft is crucial for preventing potential issues and costly repairs in the long run. Here are some common indicators that may suggest camshaft problems:

  • Unusual engine noises, such as ticking or knocking sounds
  • Poor engine power and acceleration
  • Inconsistent engine performance
  • Increased fuel consumption
  • Engine misfires or rough idling
  • Visible damage or scoring on the camshaft surface

Inspecting the Camshaft

To properly inspect a diesel engine camshaft, it is recommended to follow these steps:

  1. Prepare the necessary tools and equipment, including a flashlight, inspection mirror, and measuring calipers.
  2. Carefully remove the camshaft cover or housing to gain access to the camshaft.
  3. Visually examine the camshaft surface for signs of wear. Look for any visible damage, scoring, pitting, or discoloration.
  4. Inspect the lobes, journals, and bearings of the camshaft. Measure their dimensions and compare them with the manufacturer's specifications using the measuring calipers.
  5. Check the camshaft endplay by gently pushing and pulling on the camshaft. Excessive movement may indicate worn bearings or other issues.
  6. Ensure proper lubrication of the camshaft by checking the oil passages and making sure they are free from blockages.

Addressing Adverse Wear

If you discover adverse wear on your diesel engine camshaft during the inspection, it is crucial to address the issue promptly to prevent further damage and performance issues. Here are some possible solutions:

  • Polishing: Mild wear or scoring on the camshaft surface can often be repaired through careful polishing. However, extensive damage may require camshaft replacement.
  • Bearing Replacement: If the camshaft bearings show signs of wear, replacing them with high-quality bearings is necessary to ensure proper engine operation.
  • Oil and Filter Change: Regular oil and filter changes are essential to maintain optimal lubrication and prevent contaminants from causing further damage to the camshaft.
  • Professional Repair or Replacement: In more severe cases of camshaft wear, it is advisable to consult a professional diesel engine technician who can accurately diagnose the problem and perform the necessary repairs or replacements.
