The list of tools necessary for the maintenance of the mountain carts: the 5-magic instrument allows you to quickly fix common malfunctions
In today's increasingly popular mountain vehicle movement, 90 per cent of cyclists have experienced flashpoints such as flat tires, chain-calculation deaths and brake failure. These seemingly simple mechanical problems often require specialized maintenance tools to resolve them quickly. This paper will provide you with 12 core types of tools for the system to clean up the maintenance of mountain cars, including tools for selection techniques, use of scenery and maintenance methods to help you become a bike-man。
Composition of the basic maintenance toolbox (list of tools)
Cross screwdriver kit (ph00-ph00ph3)
It contains five commonly used specifications (crossing ph00/ph0/ph1/ph2/ph3) and recommends the selection of a professional toolkit with a magnetic absorption function. Ph00 is suitable for calibration of precisions such as brake-card clamps, pre-speed transformer oil valves, and ph3 can be used to disassembly post-linker speed limitrs。
2. Six-point wrench combination (5mm-10mm)
A magnetic hexagonal package of 13 specifications, with a special 8 mm chain adjustment wrench, was recommended. Care is taken to select tools for the smoothing design of the thorn wheel and to avoid sliding and damage to the frame during maintenance。
3. Chain maintenance tools group
- chain separators (recommended to select a compatible sram/shimano dual system)
- chain clean brushes (comprising dual-use brushes for metal/plastic)
- chain-stretching (0. 1 mm laxity)
4. Special tools for brake systems
- brake kettle (with scale)
- brake line adjuster (oil pressure test function)
- brake to compensate wrench
5. Tire pressure and supplementation load
- air pressure meters (bedding pressure indicates an error of 0. 1 bar)
- portable cylinders (with led lighting)
- self-refurbishment of the inner tyre (compatible 2. 1-2. 35 inches)
Ii. Equivalent equipment for advanced maintenance (professional tools)
1. Back-tip-chainer regulators (with angle calibration)
Resolving the problem of speed-jumping resulting from the shift of the dialer needs to be done with an angle。
2. Wheel balancers
Equipment commonly used in specialized repair shops, which detects the weight of the wheel group bias (recommended to be under 0. 5 g)。
3. Speed transformer oil pressure test pens
Oil pressure test pens with numbers, pre-detection transformer pressure (normal values: 0. 4-0. 6 mpa)。
4. Wheeled spoke-specific tool
Two specifications for the split system (m3/m4) and the british (no。
Iii. Scenes and techniques for the use of tools
1. Chain maintenance of the gold cycle
- after each ride: cleaning the slot with a chain
- weekly depth maintenance: exclusive chain oil (suggested biodegradability)
- full monthly replacement: chain wear and tear exceeding 0. 75 mm required overall replacement
2. Elements of a brake system
- the parallel of the brake blade to the wheel is 0. 5 mm
- oil pressure reconciliations need to keep the back and forth of the wheel at 0. 2 bar
- 50 emergency brake tests after each adjustment
3. Emergency tyre treatment process
- tightening brake valves immediately after an explosion
- the removal of foetal differences prior to the use of reagents objects
- inflate the replacement to 80 per cent of the standard
Tool maintenance and calibration
1. Metal tool maintenance
- it's rusty with kerosene every month
- painting of wd-40 stainproof oil before storage
- the calibration wrench is subject to annual testing by a professional body
2. Spring tool calibration
- each pre-use stretch test (standard pull values are required to conform to product instructions)
- replacing springs with more than 30% compression
3. Digital display tool maintenance
- monthly calibration of the barometer baseline
- regular cleaning of sensors
- replacement of batteries in a timely manner when they are less than 50%
V. Common error zones and solutions
1. Excessive use of force twirl
- correct operation: 2-3 operations on pre-confirmation transformer shell
- error demonstration: a single twist exceeding 5n m caused damage to the seal
2. Mixed use of brake oil
- prohibition of mixed mineral oils/synthesis
- fluid replacement cycle: 200 km or 3 months per ride (less value)
3. Chain tightening error zone
- misperception: the tighter the chain, the better
- correct standard: the promotion chain should generate 0. 2-0. 3n resistance
Vi. Training for the enforcement of tools figure
1. Freshman phase (0-100 hours riding)
- basic toolkit (approximately 200)
- focus on screwdriver use
2. Progress phase (100-500 hours)
- professional tool kits (approximately 600)
- learning chain oil pressure testing
3. Expert phase (500 hours +)
- high-end detection equipment (approximately 2000+)
- mastery of balancing techniques
Safety norms for the use of tools
1. Prohibition of single-hand operation precision tools
2. Oil additions shall take place in a static state
Conduct of a 20-km test after each repair
4. Inspection of seals immediately after water exposure
Recommendations for innovative tools
1. Smart tire pressure monitoring system (bluetooth connection app)
2. 3d print-only tool (detailorized design)
3. Electric chain tighteners (automated adjustments of up to 0. 1 mm)
The mastery of the use of these core maintenance tools will not only increase maintenance efficiency by 300 per cent, but will also effectively increase vehicle life (15-20 per cent of the projected extended shelf life). It is recommended that a tool log be set up to record the status of the spare parts for each maintenance and gradually develop its own protection system. Remember that preventive maintenance is seven times more valuable than ex post maintenance (data source: global bicycle maintenance association report)。
