This subtopic equips learners with the practical skills to service and maintain driveline components typical in classic vehicles, such as propshafts, differentials, and hubs. It encompasses safe working practices, correct tool usage, component inspection, removal and refitting procedures, and accurate documentation, ensuring that restorations maintain authenticity and roadworthiness.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The IMI Level 2 Diploma in Classic Vehicle Restoration Competence covers the practical skills and knowledge required to restore classic vehicles to a safe, roadworthy, and aesthetically pleasing condition. It includes bodywork repair, mechanical overhaul, electrical systems, and interior trimming, with a strong emphasis on workplace health and safety and industry standards.
Topic Overview
Classic vehicle restoration is a specialised field that combines traditional craftsmanship with modern techniques. This qualification covers the entire restoration process, from initial assessment and stripping down to final reassembly and testing. Students learn to work with various materials, including steel, aluminium, wood, and trim, while maintaining the vehicle's historical integrity.
The course emphasises practical competence, with students expected to perform tasks such as panel beating, welding, mechanical overhaul, and electrical fault finding. Health and safety is paramount, as restoration often involves hazardous materials and tools. Understanding the principles of vehicle construction and the importance of originality is essential for producing high-quality restorations that meet customer expectations and industry standards.
This qualification is part of the IMI's occupational framework, preparing students for careers in classic car workshops, restoration companies, or self-employment. It also provides a foundation for further study, such as the Level 3 Diploma in Classic Vehicle Restoration, and is recognised by employers across the motor industry.

Learning Objectives
What you need to know and understand
- Be able to work safely when working on vehicle driveline components, Be able to use relevant information to carry out work on vehicle driveline components, Be able to use appropriate tools and equipment when working on vehicle driveline components, Be able to carry out removal, maintenance and replacement of vehicle driveline components., Be able to record information and make suitable recommendations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating safe working practices, including appropriate PPE use, vehicle support on stands, and isolation of hazards (e.g., exhaust, sharp edges).
- Credit requires use of relevant technical data (e.g., workshop manual, torque settings) to inform disassembly, measurement, and reassembly of driveline components.
- Expect accurate selection and competent use of specialist tools (e.g., bearing pullers, dial gauges, torque wrenches) during removal, inspection, and refitting tasks.
- Assessors must observe correct component handling to avoid damage, with evidence of cleaning, inspection for wear/damage, and precise measurement (e.g., backlash, endfloat) as per manufacturer specifications.
- Credit is awarded for recording all work undertaken, including any measurements, findings, and clear recommendations for further action (e.g., part replacement or specialist machining) in a legible and professional format.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the period-correct workshop manual or technical data sheet—assessors will look for alignment with manufacturer specifications.
- 💡Take clear photographs during disassembly to document orientation and sequence; these can support your write-up and show methodical working.
- 💡Double-check all torque values with a calibrated torque wrench, and document the settings in your portfolio—precision is critical in driveline work.
- 💡When making recommendations, be specific: state what part is needed, why (with measurement evidence), and the implications of not addressing it—this demonstrates diagnostic reasoning.
- 💡Always use correct technical terminology, such as 'spot weld', 'seam sealer', 'anti-corrosion treatment', and 'torque settings'.
- 💡When answering questions about repairs, include a logical sequence: assessment, preparation, repair, finishing, and testing.
- 💡Refer to relevant regulations and standards, such as the Health and Safety at Work Act and IMI Code of Conduct, to show professional awareness.
Common Mistakes
Common errors to avoid in your coursework
- Failing to mark propeller shaft orientation before removal, leading to imbalance and vibration upon reassembly.
- Overtightening or uneven tightening of fasteners, causing distortion, thread damage, or incorrect bearing preload.
- Using incorrect lubricants or greases incompatible with classic vehicle metallurgy or seal materials, risking component failure.
- Neglecting to check runout or backlash during reassembly, resulting in noisy operation and premature wear.
- Reinstalling worn universal joints or CV joints without proper inspection, or mixing left/right side components in limited-slip differentials.
- Misconception: Any welding method is acceptable for classic cars. Correction: Spot welding is often required for original panel replacement, but MIG welding is common for repairs. Incorrect welding can distort panels or weaken joints.
- Misconception: Originality is less important than functionality. Correction: For classic vehicles, originality is a key factor in value and authenticity. Using non-original parts can reduce the vehicle's worth.
- Misconception: Health and safety is only about wearing gloves. Correction: It includes proper ventilation, fire safety, correct use of tools, and safe handling of hazardous substances like lead paint and asbestos.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A classic car has a 12-volt electrical system with a 60Ah battery. The starter motor draws 200 amps for 5 seconds. Calculate the total charge used (in ampere-hours) and the percentage of battery capacity used.
- 1.Step 1: Convert time to hours: 5 seconds = 5/3600 hours = 0.00139 hours.
- 2.Step 2: Calculate charge used: Charge (Ah) = Current (A) × Time (h) = 200 × 0.00139 = 0.278 Ah.
- 3.Step 3: Calculate percentage: (0.278 / 60) × 100 = 0.463%.
Question: Describe the process of repairing a small dent in a steel wing panel, including the tools and materials required.
- 1.Step 1: Assess the dent and clean the area.
- 2.Step 2: Use a dent puller or hammer and dolly to gently work the metal back to shape.
- 3.Step 3: Fill any remaining imperfections with body filler, then sand smooth.
- 4.Step 4: Apply primer, paint, and clear coat to match the original finish.
