Service and Repair Tyres and Tracks on Land-based Equipment
This unit covers servicing and repairing tyres, wheel assemblies, and tracks on land-based equipment. Learners will understand construction, operating principles, and maintenance procedures.
Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in Work-based Land-based Engineering Operations is a vocational qualification designed for individuals working or aspiring to work in the agricultural engineering sector. This diploma covers the essential skills and knowledge required to maintain, repair, and operate machinery and equipment used in agriculture, horticulture, forestry, and other land-based industries. It combines practical workshop skills with theoretical understanding, ensuring learners can safely and effectively perform tasks such as servicing tractors, diagnosing faults, and welding components.
This qualification is crucial for the agricultural industry, which relies heavily on mechanisation for efficiency and productivity. By mastering these engineering operations, students contribute to the smooth running of farms and estates, reducing downtime and ensuring machinery operates safely. The diploma also provides a foundation for career progression, whether into supervisory roles, specialist technician positions, or further study at Level 3. It aligns with modern agricultural practices, including precision farming and sustainable engineering, making it highly relevant to current industry needs.
Within the wider subject of land-based engineering, this diploma sits as a core entry-level qualification. It integrates with other areas such as crop production, livestock management, and estate maintenance, as engineering support is vital across all these domains. Students learn to work independently and as part of a team, developing problem-solving skills that are transferable across the sector. The work-based nature of the qualification means learners apply their learning directly in real-world settings, reinforcing their understanding through hands-on experience.
Key Concepts
Core ideas you must understand for this topic
- →Health and safety regulations: Understanding the Health and Safety at Work Act 1974, PUWER, LOLER, and COSHH, and applying them in workshop and field environments to prevent accidents and ensure compliance.
- →Engine systems and diagnostics: Knowledge of diesel and petrol engine principles, including fuel systems, cooling, lubrication, and electrical systems, with the ability to use diagnostic tools to identify faults.
- →Hydraulics and power transmission: Understanding hydraulic circuits, pumps, valves, and actuators, as well as mechanical power transmission systems like belts, chains, and gearboxes, common in tractors and implements.
- →Welding and fabrication: Proficiency in MIG, TIG, and arc welding techniques for repairing and fabricating agricultural components, including understanding weld defects and material properties.
- →Electrical and electronic systems: Ability to read wiring diagrams, test circuits, and repair lighting, starting, and control systems on modern agricultural machinery, including CAN bus systems.
Learning Objectives
What you need to know and understand
- Be able to perform service and repair operations on tyres, wheel assemblies or tracks and their components, Know the types, construction and operating principles of tyres, wheel assemblies and tracks and their components, Know how to carry out service and maintenance operations on tyres and tracks
Assessment Criteria
Key criteria assessors look for in your portfolio
- Identify different types of tyres and tracks and their uses.
- Explain operating principles of wheel assemblies and tracks.
- Perform service and repair operations safely.
- Use appropriate tools and equipment correctly.
- Follow manufacturer specifications and safety procedures.
Assessment Guidance
Guidance for achieving higher grades
- 💡Memorise key safety steps for tyre changes.
- 💡Practise identifying wear patterns.
- 💡Refer to manufacturer data sheets in answers.
- 💡Always reference health and safety in your answers, even if not explicitly asked. For example, when describing a repair, mention isolating the power source, using PPE, and following lockout procedures. Examiners look for safety awareness as a core competency.
- 💡Use technical terminology correctly and consistently. For instance, distinguish between 'fault diagnosis' (identifying the root cause) and 'fault finding' (locating the component). This demonstrates depth of knowledge and precision.
- 💡When answering questions about procedures, structure your response logically: preparation, execution, and post-work checks. For example, in a service task, list steps like gathering tools, draining oil, replacing filters, refilling, and testing. This shows systematic thinking.
Common Mistakes
Common errors to avoid in your coursework
- Incorrect tyre pressure or torque settings.
- Neglecting safety checks before repairs.
- Mixing up track tensioning procedures.
- Misconception: 'All tractor engines are the same, so servicing is identical.' Correction: Engines vary significantly between makes and models; always refer to manufacturer specifications for oil types, filter part numbers, and service intervals to avoid damage.
- Misconception: 'Welding is just melting metal together; any rod will do.' Correction: Different materials (e.g., steel, cast iron, aluminium) require specific welding rods and techniques; using the wrong rod can cause weak joints or cracking.
- Misconception: 'Hydraulic fluid is just oil; you can top up with any grade.' Correction: Using incorrect hydraulic fluid can damage seals, reduce efficiency, and void warranties; always use the specified grade (e.g., ISO 32, 46, or 68) as per the machine manual.
