Core Responsibilities

Primary Functions

Assemble a variety of engine components such as blocks, crankshafts, camshafts, pistons, and cylinder heads according to detailed engineering blueprints and work instructions.
Utilize a wide range of hand tools, pneumatic tools, and calibrated power tools to securely fasten and install engine parts to precise torque specifications.
Perform critical in-process quality checks and detailed visual inspections on components and sub-assemblies to ensure they meet strict dimensional and cosmetic standards.
Operate and interpret precision measuring instruments, including micrometers, calipers, bore gauges, and dial indicators, to verify component tolerances and clearances.
Meticulously follow complex assembly schematics, technical diagrams, and Standard Operating Procedures (SOPs) to ensure the correct build sequence and part installation.
Document the entire assembly process by recording key measurements, torque values, and component serial numbers in detailed build logs for traceability and quality assurance.
Identify, diagnose, and troubleshoot assembly issues, part discrepancies, or mechanical fitment problems, collaborating with engineering and quality teams to implement effective solutions.
Prepare and meticulously clean engine components, ensuring all surfaces are free from foreign debris and properly lubricated prior to the assembly process.
Install and correctly time critical engine systems, including timing belts, chains, and gears, to guarantee proper valve timing and overall engine operation.
Mount completed engines onto testing dynamometers or specialized test stands, carefully connecting all necessary fluid, electrical, and exhaust systems for performance validation.
Conduct preliminary engine tests, including fluid leak-down tests, compression checks, and initial start-up procedures to identify and resolve potential operational issues.
Perform final engine "dressing" by installing external components such as intake/exhaust manifolds, fuel systems, sensors, wiring harnesses, and accessory pulleys.
Set up, adjust, and calibrate assembly fixtures, jigs, and specialized tooling to ensure they are correctly configured for the specific engine model being built.
Read and interpret complex bills of materials (BOM) to accurately pick, stage, and verify the correct parts and quantities for each stage of the assembly process.
Handle and maneuver heavy engine blocks and large components safely and efficiently using overhead cranes, hoists, and other material handling equipment.
Adhere to all company and industry safety standards, including the consistent and proper use of Personal Protective Equipment (PPE) such as safety glasses, gloves, and steel-toed boots.
Rotate through different assembly stations and learn to build various engine models to increase operational flexibility and provide support across the production team.
Assist in the detailed diagnosis and complete teardown of failed or test engines to support root cause analysis investigations and drive continuous improvement initiatives.

Secondary Functions

Maintain a high level of cleanliness and organization in the designated work area, actively following 5S principles to ensure a safe and efficient environment.
Participate actively in continuous improvement (Kaizen) events aimed at enhancing assembly processes, reducing waste, and improving overall product quality.
Assist in the hands-on training and mentorship of new team members, sharing knowledge of best practices and standard operating procedures.
Manage the inventory of small parts, fasteners, and consumables at the workstation, signaling for replenishment as needed to prevent production delays.
