13 of 14 tasks have some AI capability
Exposure Trend
This score reflects estimated AI technical capability for tasks in this occupation. It does not predict employment changes, and it does not account for company-specific constraints, regulation, or adoption barriers.
Record repairs made, time spent, and parts used.
AI: Fully automatable - Recording repairs, time, and parts is fully automatable via voice/text capture, shop-management software, barcode/RFID part tracking, and AI data entry/validation.
Obtain problem descriptions from customers, and prepare cost estimates for repairs.
AI: Fully automatable - AI systems can conduct conversational intake, map symptoms to likely faults, and compute cost estimates from parts/labor databases and price lists, enabling fully automated initial estimates.
Show customers how to maintain equipment.
AI: Fully automatable - AI can deliver tailored, multimodal maintenance instructions (text, video, AR) and interactive troubleshooting that effectively shows customers how to maintain equipment remotely or in-store.
Sell parts and equipment.
AI: Fully automatable - AI-driven e-commerce and conversational agents can handle product recommendation, quoting, inventory checks and payment processing to fully automate parts and equipment sales.
Test and inspect engines to determine malfunctions, to locate missing and broken parts, and to verify repairs, using diagnostic instruments.
AI: Partial - AI can analyze diagnostic-instrument outputs and suggest faults and verification steps, but cannot fully perform physical probe placement, complex hands‑on inspection, or locate some faults without human-performed measurements or integrated sensors.
Dismantle engines, using hand tools, and examine parts for defects.
AI: Partial - Robotic disassembly is possible in standardized contexts and AI can guide humans through teardown and defect detection, but variable small-engine teardown still requires human dexterity and judgement in most shops.
Repair and maintain gasoline engines used to power equipment such as portable saws, lawn mowers, generators, and compressors.
AI: Partial - AI can diagnose, plan, and guide maintenance and routine repairs, but hands‑on mechanical repairs and adjustments on diverse portable gasoline engines remain largely manual.
Adjust points, valves, carburetors, distributors, and spark plug gaps, using feeler gauges.
AI: Partial - Precision adjustments require tactile measurement and fine manual control; AI can provide instructions, measurement interpretation, and automation in controlled fixtures, but cannot fully replace the manual process in typical field settings.
Repair or replace defective parts such as magnetos, water pumps, gears, pistons, and carburetors, using hand tools.
AI: Partial - Replacing or repairing individual mechanical components can be guided and partially automated, but the physical tasks with hand tools across varied parts and conditions are not fully automatable by AI alone in 2025.
Perform routine maintenance such as cleaning and oiling parts, honing cylinders, and tuning ignition systems.
AI: Partial - Routine maintenance tasks can be scheduled, guided, and partially automated, but many cleaning, honing, and tuning steps require manual work or specialized fixtures beyond general AI automation.
Reassemble engines after repair or maintenance work is complete.
AI: Partial - Engine reassembly can be assisted by AI instructions, checklists, and vision/torque aids, but the varied manual assembly and fitment work in repair shops is not fully automated yet.
Replace motors.
AI: Partial - Motor replacement can be robotically performed in controlled industrial contexts, but in most field and small‑engine scenarios it still requires human lifting, alignment, and custom fitting that AI alone cannot fully execute.
Grind, ream, rebore, and re-tap parts to obtain specified clearances, using grinders, lathes, taps, reamers, boring machines, and micrometers.
AI: Partial - CNC and automated machining can perform many precision operations, but small-shop manual setups, fixturing, and ad-hoc rework still require human machinists, so automation is partial.
Remove engines from equipment, and position and bolt engines to repair stands.
AI: Not automatable - Removing and physically mounting engines requires heavy lifting, nuanced manipulation, and variable fixturing that autonomous systems are not broadly capable of performing in general shop environments by 2025.
