Service and Repair Tyres and Tracks on Land-based Equipment
This element equips learners with the essential skills to inspect, service, and repair tyres, wheels, and track systems on agricultural, horticultural, and groundcare machinery. Practical understanding of construction, operating principles, and correct maintenance procedures ensures safe, efficient operation and prolongs component lifespan, directly impacting machine performance and operator safety.
Assessment criteria
Topic Overview
The IMI Level 2 Diploma in Work-based Land-based Engineering Operations (Power Equipment) is a vocational qualification designed for individuals working or aspiring to work in the land-based engineering sector, focusing on power equipment such as lawnmowers, chainsaws, tractors, and other machinery used in agriculture, horticulture, and forestry. This diploma combines practical workplace experience with theoretical knowledge, covering essential skills like servicing, repairing, and maintaining power equipment to industry standards. It is part of the Institute of the Motor Industry (IMI) occupational qualifications framework, ensuring learners gain nationally recognised competencies that align with employer expectations.
This qualification is critical for students aiming to build a career in land-based engineering, as it provides a solid foundation in health and safety, diagnostic techniques, and workshop practices specific to power equipment. By completing this diploma, learners demonstrate their ability to work independently and as part of a team, using specialised tools and diagnostic equipment to troubleshoot and rectify faults. The course also emphasises environmental awareness and sustainable practices, reflecting modern industry demands. Mastery of this diploma opens pathways to advanced apprenticeships, supervisory roles, or specialised certifications in areas like precision farming or renewable energy systems.
Key Concepts
Core ideas you must understand for this topic
- →Health and Safety Regulations: Understanding COSHH, PUWER, and LOLER regulations to ensure safe operation and maintenance of power equipment, including risk assessments and safe manual handling.
- →Engine Systems: Knowledge of two-stroke and four-stroke engine principles, including fuel systems, ignition systems, cooling, and lubrication, to diagnose and repair common faults.
- →Electrical and Hydraulic Systems: Ability to interpret wiring diagrams, test circuits, and maintain hydraulic components like pumps, valves, and cylinders used in power equipment.
- →Diagnostic Techniques: Use of multimeters, compression testers, and manufacturer diagnostic software to identify mechanical and electrical issues systematically.
- →Workshop Practices: Proper use of hand tools, power tools, and lifting equipment, along with documentation of service records and parts ordering.
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
- Award credit for correctly identifying tyre or track type and explaining its construction features (e.g., radial ply, cross-ply, rubber track versus steel track) in the context of the machine's application.
- Learners must demonstrate the safe removal, thorough inspection (tread depth, sidewall damage, bead condition), and accurate refitting of a wheel assembly, using calibrated torque tools to manufacturer specifications.
- Expect candidates to perform a systematic service on a track undercarriage, checking and adjusting tension, inspecting sprockets, idlers, and rollers for wear, and lubricating pivot points as per the service schedule.
- Evidence of selecting appropriate repair methods for minor tyre damage (e.g., plug/patch repair within repairable zones) or documenting when replacement is necessary, with justification linked to safety and operational standards.
Assessment Guidance
Guidance for achieving higher grades
- 💡During observed practical tasks, talk through your risk assessment and the safety precautions you’re taking, such as chocking wheels and releasing air pressure before demounting a tyre; this demonstrates underpinning knowledge.
- 💡If confronted with a written question on tyre construction, use diagrams to support your explanation—label carcass plies, beads, and belt packages if present.
- 💡For track service, systematically follow the manufacturer’s inspection checklist from the operator’s manual; showing you can navigate technical literature impresses assessors.
- 💡Always link your answers to specific regulations or manufacturer guidelines. For example, when discussing a repair, mention the relevant PUWER requirement or the service manual step. This shows depth of understanding.
- 💡In practical assessments, demonstrate a systematic diagnostic approach: start with the simplest checks (fuel, spark, compression) before moving to complex systems. Examiners award marks for logical reasoning.
- 💡Use correct terminology consistently. For instance, refer to 'ignition coil' not 'spark plug thing', and 'hydraulic relief valve' not 'pressure thingy'. This demonstrates professional knowledge.
Common Mistakes
Common errors to avoid in your coursework
- Applying wheel nut torque without understanding the correct sequence or stage tightening, often resulting in uneven clamping, warped brake discs, or loose wheels.
- Confusing tyre load and speed ratings, leading to the fitting of an underrated tyre that can fail under operational stress.
- Over-tensioning rubber tracks, which increases wear on drive lugs and bearings, or under-tensioning, causing 'de-tracking' during manoeuvres.
- Neglecting to clean and inspect wheel studs and nut seats before assembly, which can lead to false torque readings and subsequent fastener failure.
- Misconception: 'All power equipment engines are the same, so I can use the same repair method for any machine.' Correction: While basic principles apply, each manufacturer has specific tolerances, service intervals, and diagnostic codes. Always refer to the service manual for the exact model.
- Misconception: 'If the equipment starts, it doesn't need servicing.' Correction: Many faults, like worn belts or contaminated fuel, don't prevent starting but cause inefficiency or breakdowns later. Regular servicing prevents costly repairs.
- Misconception: 'Hydraulic fluid never needs changing.' Correction: Hydraulic fluid degrades over time due to heat and contamination, leading to component wear. Follow manufacturer schedules for fluid and filter changes.
