Exercise: The Motorhand's Challenge
Scenario:
A drilling rig is experiencing engine problems, resulting in a loss of power. The Motorhand is tasked with diagnosing the issue. He notices the engine is overheating and the oil pressure gauge is reading low.
Your Task:
- Identify the two potential problems based on the Motorhand's observations.
- Explain why these problems could be causing the engine to overheat and lose power.
- Suggest two steps the Motorhand could take to address the issue.
Exercice Correction
**Potential Problems:** 1. **Insufficient Lubrication:** Low oil pressure indicates a lack of sufficient lubrication to the engine components. This can lead to friction and overheating. 2. **Cooling System Malfunction:** Overheating suggests a problem with the engine's cooling system, such as a clogged radiator or a malfunctioning thermostat. **Explanation:** * **Insufficient lubrication:** Without adequate lubrication, engine components experience increased friction, generating heat. This can lead to overheating and potential engine damage. * **Cooling System Malfunction:** A faulty cooling system prevents the engine from dissipating heat effectively, causing it to overheat and potentially seize. **Steps to Address the Issue:** 1. **Check Oil Levels and System:** The Motorhand should immediately check the oil level and inspect the oil filter for any blockages. If the oil level is low, it should be topped off. 2. **Inspect Cooling System:** The Motorhand should inspect the radiator for any blockages or leaks. He should also check the thermostat to ensure it's functioning properly and allowing coolant to circulate.
