Use micrometers, calipers, and dial indicators to verify tolerances on shafts, bearings, and interference fits during rebuilds.
Enforce MSHA and company safety protocols during all maintenance activities.
Ensure proper documentation of lockout/tagout procedures and hazard assessments.
Maintain accurate service records, diagnostic reports, and inventory logs.
Assist in budgeting for parts, tools, and equipment upgrades.
