FTE
The FTE clutch master cylinder is a high-quality replacement hydraulic component for selected Porsche 911 and 930 models fitted with a G50-series gearbox. Corresponding with Porsche part number 91142317103, it is designed to replace a worn, leaking or internally failing original cylinder and restore smooth, reliable clutch operation.
Fits:
Porsche 911 1987 - 1989
Porsche 930 with G50/50 GearBox
When the clutch pedal is pressed, the master cylinder converts pedal movement into hydraulic pressure. This pressure travels through the clutch line to the slave cylinder, which operates the clutch release mechanism. A correctly functioning master cylinder is therefore essential for full clutch disengagement, clean gear selection and consistent pedal feel.
Manufactured by FTE, this replacement unit is designed for accurate fitment, dependable sealing and reliable operation under repeated hydraulic pressure cycles. It is suitable for routine servicing, gearbox repairs and the restoration of classic Porsche models with hydraulic clutch actuation.
What This Part Does
The clutch master cylinder supplies hydraulic pressure to the slave cylinder whenever the clutch pedal is depressed. This allows the clutch to disengage from the engine so that gears can be selected without excessive resistance or transmission wear.
A serviceable clutch master cylinder helps maintain:
• Smooth clutch engagement and disengagement
• Consistent pedal pressure and travel
• Clean, accurate gear changes
• Correct operation of the clutch slave cylinder
• Secure containment of hydraulic fluid

Molub-Alloy Paste White T – High Performance Assembly & Anti-Fretting Paste
Molub-Alloy Paste White T is a premium high-performance assembly paste designed to provide exceptional protection against fretting corrosion, stick-slip, wear, and seizure in demanding automotive, industrial, and workshop applications.
This white assembly paste applies cleanly and appears almost colourless when spread as a thin layer, making it ideal for precision assembly work where cleanliness and protection are equally important.
Formulated for universal assembly and thin-film lubrication applications, Molub-Alloy Paste White T helps simplify component assembly and future disassembly while protecting contact surfaces against corrosion, vibration-related wear, and moisture ingress.
Its advanced formulation provides excellent resistance to both hot and cold water while delivering long-lasting corrosion protection under harsh operating conditions.
Particularly effective in applications exposed to vibration and frictional movement, the paste helps prevent fretting corrosion and reduces stick-slip behaviour, making it ideal for hydraulic cylinders, open lubrication points, threaded assemblies, sliding surfaces, and mechanical components subject to oscillating movement.
The product also helps eliminate squeaking noises and improves smooth operation in moving assemblies exposed to high loads and thermal stress.
Suitable for temperatures ranging from -30°C to +250°C, Molub-Alloy Paste White T delivers reliable lubrication and anti-corrosion performance across a wide range of workshop, automotive, and engineering environments.
