 WARNING!

Risk of injury and poisoning working with hydraulic fluid!
Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure. When disengaging hydraulic lines without depressurising the system, dangerous skin or eye injuries can occur due to the very high pressures (in excess of 200 bar). If hydraulic fluid, particularly central hydraulic fluid (especially harmful), comes into contact with unprotected skin, this can cause damage to the skin.
If hydraulic fluid is swallowed, this can lead to poisoning symptoms such as headache, dizziness, nausea, vomiting, diarrhoea, cramps and unconsciousness.
Wear protective gloves, protective clothing and eye protection.
| • | Depressurise and drain the system if necessary when commencing work on hydraulic systems.
| | • | Never put hydraulic fluid into beverage containers.
| | • | Ensure sufficient ventilation, especially in the case of central hydraulic fluid.
| | • | Ensure that only authorised persons have access to hydraulic fluid.
| | • | Immediately seal disconnected leads and hoses and the connections to the assembly with blind plugs.

WARNING!
| |
Risk of injury and poisoning working with hydraulic fluid under pressure!
Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure. If any part of the hydraulic circuit has failed, a possibility of the system not depressurising can occur. Extra precaution is required in this event. If hydraulic fluid is swallowed, this can lead to poisoning symptoms such as headache, dizziness, nausea, vomiting, diarrhoea, cramps and unconsciousness.
Always wear skin protection cream, protective gloves and safety glasses when working on a potentially pressurised system.
| |
WARNING!
| |
Possible fluid spills from vehicle systems during repairs or maintenance.
Risk of thermal incidents, slip hazards, corrosion of electrical components, failure of electrical or mechanical components or unwanted odours.
Always limit fluid spills and fully clean the spilled fluid after repairs or maintenance.

Remove pressure lines - Suspension - Rear
| | | Care Point: | The suspension system must be depressurised before any work on the hydraulic system.
|
| | | 1. | Connect McLaren Diagnostic System, proceed to Diagnostic Toolbox within Chassis Control Unit (CCU).
| | | 2. | Access Sequences section.
| | | 3. | Carry out APMU Maintenance Start.
| | |
|
| | | Care Point: | Drain the fluid into a suitable container.
|
| Care Point: | Record the amount of fluid drained from the system.
|
| Care Point: | Do not mix fluid types.
|
| Care Point: | Plug or cover airbrake hose unions once disconnected.
|
| | | 4. | Disconnect the airbrake hoses (1). 20 Nm
| | | 
|
| 5. | | | | 6. | Disconnect suspension pressure lines from the actuator (3).
| | | 
|
| 7. | | | | | | Care Point: | Drain the fluid into a suitable container.
|
| Care Point: | Record the amount of fluid drained from the system.
|
| | | 8. | Disconnect suspension pressure line from longitudinal hose.
| | | 
|
| 9. | | | | 10. | Detach suspension pressure lines from retaining clips (6).
| | | 11. | Remove suspension pressure lines from vehicle.
| | | 
|
Install pressure lines - Suspension - Rear
| | | Care Point: | Check the condition of the O-rings and replace if necessary.
|
| | | 1. | Top up gearbox clutch oil using new clutch oil only. FFL-4
| | | 2. | Install components in reverse order, excluding rear diffuser.
| | | | | Care Point: | The procedure below must be claimed separately if you make a warranty claim.
|
| | | 3. | | | | 4. | Connect McLaren Diagnostic System, proceed to Diagnostic Toolbox within Transmission Control Unit (TCU).
| | | 5. | Access Sequences section.
| | | | | Care Point: | Safety Critical! Make sure no technicians are working at rear of vehicle whilst calibration sequences are in operation.
|
| Care Point: | Air Brake Bleed sequence also completes the Calibration sequence. It is not required to carry out both sequences separately.
|
| | | 6. | Carry out Air Brake Bleed sequence.
| | | 7. | Check airbrake and suspension for leaks.
