Steps for Heavy Equipment Troubleshooting 

Below are the steps for heavy equipment troubleshooting to help fix issues more quickly. Steps for Heavy Equipment Troubleshooting 

1. Ensure the problem is actually happening. 

a. Gather information related to the trouble. 

b. Listen to complaints from the operator of the unit experiencing trouble. What the operator did during the trouble Was the unit operating properly before the trouble occurred? 

2. Identify the trouble by taking notes 

 a. Organize the facts that have been collected. 

b. Interpret the information obtained. 

c. Operating conditions Geographical conditions (dusty, sandy, unit operating at high altitudes) Weather (very cold, very hot, high humidity, etc.) When the trouble occurred, was the operator experienced in operating the unit? d. Machine / Engine history What preventive maintenance has been performed? What repairs have been done previously? 

3. Visually inspect the Machine or Engine 

a. Gather additional necessary information. Visual inspection of sensors. Technical testing such as operational adjustments and standards. Refer to the service manual, bulletins, and schematic diagrams. 

b. Verify operational problems 

c. Collect evidence. 

4. Write down all possible causes 

a. Identify possible malfunctions: Identify as many potential causes of the trouble as possible. 

If the trouble does not have a clear cause, narrow it down to subsystems and try again to identify the cause. Gather as much information as possible if the potential cause is difficult to identify. 

5. Conduct tests and record the results 

a. Check possible damages Gather additional information about possible damages. Vary the testing of a component simultaneously to test potential causes if you are not familiar with the system or component. If the testing takes time and is expensive, try conducting tests to rule out several possible causes using a systematic approach. Do not assume that all parts/components are always functioning properly. Reduce the number of possible causes. 

b. Simulate the Problem Test the suspected component or system to confirm that it is the cause. Ask the operator to simulate the conditions when the trouble occurs. 

c. Record all test results, replaced parts, and adjustments made. 

d. Follow all rules or work SOPs when conducting tests.

6. Find the root of the problem 

a. Narrow down the causes of the problem. 

b. Identify the root cause of the problem. 

7. Repair Damage 

a. Perform repairs/eliminate troubles on the unit according to proper standard procedures. 

b. Record the test results, parts used, and adjustments made. 

c. Follow safety rules during the repair process. 

8. Analyze why the trouble occurred 

a. Review each solution obtained with colleagues. 

b. If the damage persists after testing the solution (or new trouble arises), perform the troubleshooting procedure again. 

c. Fill out the Fault Analysis paperwork and create technical information.
