NCCER Industrial Maintenance Mechanic study plan

Identify and describe the application of the major valve types (gate, globe, ball, butterfly, check, plug) and at least 10 common pipe fittings without notes.

Cut, ream, and thread a length of steel pipe, then verify thread engagement and fit by assembling it to a fitting.

Select the correct gasket material, flange rating, and bolting for three different service conditions (steam, potable water, caustic chemical).

Demonstrate the star/cross bolt-tightening sequence on a flange and explain why the pattern and torque increments matter.

Compare pipe, tubing, and hose systems and state one installation rule and one inspection point for each.

Assemble one flared and one compression tubing joint, then inspect each for common defects (cracks, over-tightening, wrong ferrule seating).

Write a job safety analysis for a valve replacement that lists hazards, required PPE, energy sources, and permit needs.

Sequence the steps to isolate, drain, vent, and verify zero energy on a process line before breaking a flange.

Describe confined space entry and hot work precautions that apply to piping repair work.

Explain how to inspect and store gaskets and how to recognize a leaking flange that requires immediate shutdown.

Differentiate chain, V-belt, timing-belt, gear, and direct-coupling drives, giving one application and one common failure mode for each.

Calculate driven speed and torque for belt and gear drives from driver rpm and sheave or gear tooth counts.

Sequence a shaft alignment job using straightedge/feeler gauge, then dial indicator, then laser methods, and state typical acceptable misalignment limits.

List the installation steps for a flexible coupling, including key fit, hub runout, and alignment check before startup.

Identify symptoms of misalignment and imbalance (vibration, coupling wear, bearing heat) and match each to a corrective action.

Recognize and name hydraulic and pneumatic schematic symbols for pumps, valves, cylinders, filters, and reservoirs.

Compare hydraulic and pneumatic power transmission in terms of fluid, force capability, response, and typical applications.

Trace fluid flow through a basic hydraulic circuit containing a pump, relief valve, directional control valve, and cylinder.

Diagnose three given symptoms (slow cylinder, overheating oil, drifting load) and name the most likely cause and first check for each.

Explain the purpose and safe adjustment of a pressure relief valve.

Trace a pneumatic circuit that includes an FRL unit, control valve, and actuator, and list the maintenance point at each component.

Explain how contamination, moisture, and air entrainment damage a fluid power system and how to prevent each.

Describe the steps to safely bleed stored hydraulic and pneumatic energy before servicing a component.

Interpret pressure and flow readings to decide whether a pump, valve, or actuator is the faulty element.

Outline a preventive maintenance routine for filters, fluid sampling, and hose/ fitting inspection.

Classify bearing types (ball, cylindrical and tapered roller, thrust, sleeve) and match each to a load and speed application.

Describe correct installation and removal methods for bearings and name the practices that damage them (misalignment, wrong fit, shock loading).

Choose lubricant type, viscosity, and grease quantity for given speed, load, and temperature conditions.

Explain lip seal, mechanical seal, O-ring, and packing arrangements and list the usual causes of leakage for each.

Apply lockout/tagout, PPE, and hazard communication requirements to a bearing and seal replacement task.

Select the correct hand or power tool for six described tasks and state the specific safety rule for each.

Identify fastener types and thread standards, and explain torque versus tension and when to use a torque sequence.

Evaluate sling angle effects on load tension and list the rejection criteria for slings, shackles, and rigging hardware.

Read a mechanical drawing or P&ID: interpret title block, line types, symbols, dimensions, and bill of materials.

Lay out and mark a bolt-hole pattern from dimensions, then verify spacing within tolerance.

Apply Ohm's law and compare series versus parallel circuits using worked examples.

Identify motor control components (disconnect, starter, contactor, overload) and describe safe electrical lockout steps.

Build a preventive maintenance schedule for five typical assets listing task, frequency, and acceptance criteria.

Distinguish preventive from predictive techniques (vibration analysis, thermography, oil analysis, ultrasound) and match each to an asset.

Complete a full-length timed practice exam and review every missed item to its source concept.
