Summary: This study investigates the challenges and techniques associated with the extraction of stuck fuel injectors from diesel engines. Sticking or seized fuel injectors can impede engine performance, fuel efficiency, and overall functionality. The research focuses on analyzing common causes of injector seizure, ranging from carbon deposits to corrosion, and explores practical approaches for successful removal. The results of hydraulic puller were obtained by comparative analysis between numerous tests. Throughout the process, the data changes from trial to trial. All data collected showed how the project worked effectively and efficiently. The testing of two fuel injector removal methods, namely the hydraulic puller and the impact fuel injector puller, revealed distinct characteristics. The hydraulic puller method consistently generated pressure around 500 psi and demonstrated quick and relatively consistent removal times, ranging from 4 to 6 seconds. On the other hand, the impact puller, operated manually, exhibited more variability in removal times, spanning from 14 seconds 58 seconds, with no specific information provided about the generated pressure. These findings suggest that the hydraulic puller method offers a quicker and more consistent removal process compared to the impact puller method, indicating potential differences in efficiency and performance between the two tools. The evaluation results indicate that the hydraulic puller for diesel engine fuel injectors achieved a general weighted average of 4.53, reflecting high acceptance. This demonstrates strong satisfaction with the puller’s overall functionality among respondents. Finally, this research study provides implications and suggestions towards enhancing tools that can be used in the field of automotive industries.

This study investigates the challenges and techniques associated with the extraction of
stuck fuel injectors from diesel engines. Sticking or seized fuel injectors can impede engine
performance, fuel efficiency, and overall functionality. The research focuses on analyzing
common causes of injector seizure, ranging from carbon deposits to corrosion, and explores
practical approaches for successful removal. The results of hydraulic puller were obtained
by comparative analysis between numerous tests. Throughout the process, the data changes
from trial to trial. All data collected showed how the project worked effectively and
efficiently. The testing of two fuel injector removal methods, namely the hydraulic puller
and the impact fuel injector puller, revealed distinct characteristics. The hydraulic puller
method consistently generated pressure around 500 psi and demonstrated quick and
relatively consistent removal times, ranging from 4 to 6 seconds. On the other hand, the
impact puller, operated manually, exhibited more variability in removal times, spanning
from 14 seconds 58 seconds, with no specific information provided about the generated
pressure. These findings suggest that the hydraulic puller method offers a quicker and more
consistent removal process compared to the impact puller method, indicating potential
differences in efficiency and performance between the two tools. The evaluation results
indicate that the hydraulic puller for diesel engine fuel injectors achieved a general
weighted average of 4.53, reflecting high acceptance. This demonstrates strong satisfaction
with the puller’s overall functionality among respondents. Finally, this research study
provides implications and suggestions towards enhancing tools that can be used in the field
of automotive industries.
