NCCER Millwright study plan

NCCER Millwright · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Safety & Tools and Equipment

  • Match the required personal protective equipment to five described millwright tasks and justify each selection against the hazard present.

  • Write a job hazard analysis for a combined lift-and-align task that lists at least six hazards, the controls for each, and the residual risk.

  • Inspect five hand and power tools against a written checklist and record pass/fail plus the specific rejection reason for any failure.

  • State the lockout/tagout sequence for a motor-driven pump and list the verification steps that confirm zero energy before work begins.

  • Identify the correct fire extinguisher class and the emergency response sequence for an oil fire and an electrical fire in a shop setting.

Your checkpoint

A signed 10-item safety and tool-inspection packet containing one complete JHA, five tool inspection records, and a written LOTO procedure.

Week 2

Blueprints, Schematics, and Layout & Precision Measurement and Layout

  • Extract pipe size, flow direction, nozzle orientation, and instrument tags from a P&ID and a general-arrangement drawing for one vessel.

  • Convert dimensions between architectural, engineering, and metric scales and verify three field dimensions by calculation.

  • Measure five gauge-block-checked parts with a micrometer, dial caliper, and height gauge and record each reading to within 0.001 in.

  • Set up a dial indicator on a shaft and record total indicated runout, then compare the result to an allowable limit.

  • Locate and lay out a bolt-hole pattern from drawing coordinates within 1/32 in. using layout instruments only.

Your checkpoint

A dimension takeoff sheet with 15 verified dimensions, a 10-reading measurement log kept inside tolerance, and a marked-up layout sketch of one bolt pattern.

Week 3

Rigging and Lifting

  • Calculate load weight from volume and material density and compare it to the rated capacity of the selected sling and hardware.

  • Compute sling tension for two-leg and four-leg bridle hitches at 30, 45, and 60 degrees and apply the correct angle factor.

  • Inspect slings, shackles, and hooks and identify the capacity markings, rejection criteria, and removal-from-service conditions for each.

  • Locate the center of gravity of an asymmetrical load and select the hitch type and tag line arrangement that keeps the load controlled.

  • Read a load chart and determine the maximum radius and boom configuration permitted for a stated load.

Your checkpoint

A complete written lift plan for a 4,000 lb skid including weight calculation, sling tension math, hardware selection with design factor, and a labeled rigging sketch.

Week 4

Machinery Installation and Alignment

  • Verify a baseplate and foundation against the layout drawing, checking elevation, anchor bolt pattern, hole allowance, and shim stack thickness.

  • Level a machine on shims to the specified elevation using a precision level and record the readings in both axes.

  • Perform a soft-foot check at all mounting points and correct any gap greater than 0.002 in. before proceeding to alignment.

  • Check for pipe strain by measuring coupling movement while piping is connected and disconnected.

  • Describe the grout placement and cure sequence and identify the conditions that require a dry-pack or epoxy grout instead of a cementitious grout.

Your checkpoint

A completed installation checklist for a simulated pump and motor set with elevation readings, shim records, and documented soft-foot correction at every mounting point.

Week 5

Shaft Alignment and Couplings

  • Explain and demonstrate the reverse dial indicator method, recording readings at the 12, 3, 6, and 9 o'clock positions.

  • Compute vertical and horizontal shim corrections from dial readings and apply bar-sag and indicator-sag corrections to the raw numbers.

  • Set up a laser shaft alignment system, enter machine dimensions, and interpret the offset and angularity results screen.

  • Identify coupling types from a sample set and match each to an application based on torque, misalignment tolerance, and service conditions.

  • Inspect a coupling for fit, key condition, and end float and state the acceptance criteria for each.

Your checkpoint

An alignment worksheet showing raw dial readings, corrected values, computed shim moves, and a final alignment documented within 0.002 in. offset and 0.0005 in./in. angularity.

Week 6

Bearings, Seals, and Lubrication

  • Classify bearings from a sample set by type and state the load direction, speed limit, and typical mounting method for each.

  • Mount and remove a rolling element bearing using an induction heater and a press without imposing load through the rolling elements.

  • Select a lubricant by viscosity grade for a stated speed and temperature and specify the grease quantity and re-lubrication interval for one bearing.

  • Install a lip seal and a mechanical seal with correct orientation, shaft finish requirement, and running clearance.

  • Diagnose three lubrication faults (over-greasing, under-lubrication, wrong viscosity) from described symptoms and oil or grease condition.

Your checkpoint

A bearing and seal installation log covering three components with recorded fits, internal clearances, lubricant specification, and interval.

Week 7

Hydraulic and Pneumatic Systems

  • Trace a hydraulic schematic and identify the pump, relief valve, directional valve, flow control, and actuator with their symbols.

  • Calculate cylinder extend force, retract force, rod speed, and pump flow requirement from bore, rod diameter, pressure, and delivery rate.

  • Perform a safe depressurization sequence and interpret a fluid sample report against target cleanliness and water content limits.

  • Diagnose no-movement, slow-cycle, and overheating faults using gauge readings and a written decision sequence.

  • Identify the causes and corrections for air entrainment, cavitation, and external leakage in a pneumatic circuit.

Your checkpoint

A circuit analysis sheet for two schematics with calculated forces and flows plus a written troubleshooting decision tree that resolves one fault from symptoms to root cause.

Week 8

Preventive and Predictive Maintenance & Safety & Shaft Alignment and Couplings

  • Build a preventive maintenance task list for a rotating equipment train from manufacturer intervals, criticality, and failure history.

  • Collect vibration readings on a test asset and trend them against ISO severity zones to flag an alarm condition.

  • Interpret a thermography image and an oil analysis report and state the corrective action each finding drives.

  • Assemble a 30-day spaced review schedule covering all ten domains, weighted toward shaft alignment, rigging, and installation.

  • Complete a 50-question practice exam and score at least 80 percent, then log every missed item by domain.

Your checkpoint

A predictive maintenance report on one asset plus a scored practice exam with a domain-by-domain error log and a written 30-day review calendar.

Milestones

Week 2: Record all 10 measurement readings within stated tolerance and reproduce a bolt pattern to within 1/32 in. without rework.

Week 4: Complete the installation checklist with every mounting point soft-foot corrected to 0.002 in. or less before starting alignment work.

Week 5: Produce a full reverse-dial alignment worksheet and land the machine within 0.002 in. offset and 0.0005 in./in. angularity on the first correction attempt.

Week 6: Demonstrate bearing mounting and seal installation on three components with no damage and all fits and clearances recorded within specification.

Week 8: Score 80 percent or higher on the 50-question practice exam with no domain scoring below 70 percent.
