Core Responsibilities

Primary Functions

Install, align, and secure new equipment and machinery (conveyors, pumps, compressors, gearboxes, presses, packaging lines) according to engineering drawings and manufacturer specifications, ensuring precise tolerances and safe operation.
Perform hands-on mechanical assemblies and disassemblies of large rotating and stationary equipment, including removal and replacement of shafts, couplings, bearings, seals, sprockets, and gear sets with proper lifting and rigging techniques.
Conduct precision shaft and machine alignment using laser alignment tools, dial indicators, and optical alignment methods to reduce vibration, minimize wear, and extend equipment life.
Troubleshoot complex mechanical failures by systematically diagnosing root causes through inspection, measurements, oil analysis, vibration data, and functional testing to recommend corrective actions.
Repair or rebuild gearboxes, pumps, motors (mechanical aspects), hydraulic power units, and pneumatic actuators; replace worn parts, reseal components, and verify tolerances and clearances.
Perform preventive and predictive maintenance tasks per maintenance schedules: lubrication, belt and chain tensioning, bearing lubrication and replacement, filter changes, and visual inspections to maximize uptime.
Fabricate and modify mechanical components using shop equipment: cut, drill, mill, weld, and machine parts to restore or improve machinery functionality when replacement parts are unavailable.
Interpret and work from blueprints, mechanical drawings, P&IDs, wiring schematics, and equipment manuals to perform accurate installations, repairs, and modifications.
Execute rigging operations to move and position heavy equipment using cranes, hoists, chainfalls, and slings; prepare lift plans, calculate load weights, and coordinate lift teams for safe lifts.
Perform field machining tasks such as on-site boring, line boring, grinding, and tolerance restoration to repair component housings and align mating surfaces.
Commission and test machinery after installation: perform run-in procedures, balance rotating equipment, verify safety interlocks, and record baseline performance metrics.
Conduct safety-critical tasks including lockout/tagout (LOTO), confined space entry, hot work permits, and adherence to OSHA/NFPA standards when working on energized or hazardous systems.
Maintain accurate maintenance logs, work orders, parts lists, and downtime reports in CMMS (Computerized Maintenance Management System) to support spare parts management and continuous improvement.
Coordinate with electricians, controls technicians, production leads, and engineers to troubleshoot issues that cross mechanical and electrical domains, ensuring minimal production disruption.
Perform vibration analysis, thermography inspections, and other condition-monitoring activities, and escalate machine health concerns to the reliability or engineering teams.
Replace, align, and tension conveyor systems, sprockets, idlers, and drive components to maintain efficient product flow and reduce jam/damage incidents.
Conduct emergency repairs and rapid response troubleshooting outside normal hours when required to restore critical equipment and meet production commitments.
Install and adjust guarding, safety devices, and interlocks to comply with plant safety policies and prevent operator injuries.
Mentor apprentices and junior maintenance staff by demonstrating best-practices in mechanical repair, safe rigging, and accurate measurement techniques.
Coordinate materials and parts procurement: verify part numbers, collaborate with storeroom personnel, and advise on long-lead component sourcing to minimize future downtime.
Perform periodic calibration and verification of precision tools (torque wrenches, micrometers, calipers, lasers) to ensure measurement accuracy and quality workmanship.
Document and recommend design improvements or engineering changes to improve machine reliability, maintainability, and throughput.

Secondary Functions

Support continuous improvement initiatives (Kaizen, 5S, TPM) by identifying and implementing mechanical improvements to reduce waste and improve efficiency.
Assist maintenance planning and scheduling by providing accurate labor estimates, parts needs, and technical input for planned shutdowns.
Provide on-the-job training and safety coaching to production personnel on basic preventive maintenance and proper equipment operation techniques.
Participate in root cause analysis (RCA) and problem-solving teams to reduce repeat mechanical failures and enhance mean time between failures (MTBF).
Help develop and maintain spare parts inventories and recommend strategic stocking levels for critical mechanical components.
Contribute to capital project installations by providing mechanical expertise during planning, pre-assembly, and site installation phases.
