Diagram ref no 28
This component is used on selected Porsche Turbo clutch hydraulic systems, including 993TT, 996TT and 997TT applications.
What This Part Does / Functions
• Stores hydraulic pressure within the clutch operating system
• Helps support smooth and consistent clutch operation
• Assists the clutch slave cylinder hydraulic circuit
• Helps maintain stable pressure during clutch actuation
• Supports correct clutch engagement and disengagement
• Replaces a weak, faulty, leaking or failed pressure accumulator
• Provides correct OE Porsche hydraulic specification and fitment
• Supports reliable operation of the factory clutch hydraulic system.
Why Replace This Part?
The pressure accumulator is a hydraulic component that can weaken or fail over time due to internal diaphragm wear, pressure cycling, age, fluid condition or seal deterioration. If the accumulator no longer stores pressure correctly, the clutch hydraulic system may not operate as intended. Replacing it with an OE Genuine Porsche pressure accumulator helps restore correct hydraulic pressure reserve and supports reliable clutch operation on high-performance Turbo models.
Common Symptoms of a Faulty Pressure Accumulator
• Heavy, inconsistent or abnormal clutch pedal feel
• Difficulty selecting gears
• Clutch engagement or disengagement issues
• Hydraulic pressure loss in the clutch system
• Clutch slave cylinder operating faults
• Fluid leakage around the accumulator or hydraulic fittings
• Reduced clutch system response
• Fault confirmed during hydraulic clutch system diagnosis.
When to Replace This Part
• If the clutch hydraulic system is not holding pressure correctly
• If clutch operation becomes inconsistent or difficult
• If the accumulator is leaking or damaged
• During clutch slave cylinder or hydraulic line repair
• During gearbox or clutch system overhaul
• If hydraulic pressure testing confirms accumulator failure
Where It Fits on the Car
This pressure accumulator fits within the clutch hydraulic operating system, associated with the clutch slave cylinder / pressure line circuit on selected Porsche Turbo models.
Correct installation and bleeding procedures must always be followed. Clutch hydraulic components are critical to vehicle operation and should be fitted by a qualified technician.
