Clutch Slave Cylinder Hose Volvo M46 M47 M90

Clutch slave cylinder hose for Volvo M46/M47/M90

Flexible clutch hose connecting the rigid line or bracket to the slave cylinder on Volvo 240, 740 and 940 models with an M46, M47 or M90 manual gearbox. Replaced to ensure reliable and consistent clutch operation in everything from road use to demanding circuit and rally driving.

This is the short flexible hose near the gearbox that accommodates movement between the body and drivetrain while ensuring pressure from the master cylinder reaches the slave cylinder without placing unwanted load on the pipes or fittings. On older Volvo builds it is a service item: age, heat and fluid degrade the material, causing a spongy pedal and increasing the risk of leaks. In motorsport use—track days, drifting, rallying and endurance racing—a sound hose is simple insurance for consistent pedal height and trouble-free shifting under heat and vibration.

• Installed between the chassis bracket or rigid line and the slave cylinder on the gearbox
• Used on Volvo 240/740/940 models with an M46, M47 or M90 manual gearbox
• Stable operation even with uprated pressure plates and at higher operating temperatures
• Provides the necessary flexibility for engine and gearbox movement without straining pipes and fittings
• Suitable for builds where reliability is a priority: circuit driving, drifting, rallying and fast road use
• A practical maintenance replacement when upgrading the clutch or refurbishing the hydraulic system

Technical specifications

Installation and usage tips

• Preparation: Clean the threads and unions and use penetrating oil if required. Have new sealing washers ready if your connection uses a banjo fitting.
• Fluid: Use fresh brake/clutch fluid of the correct specification, normally DOT 4. Flush the system if the existing fluid is dark or contaminated.
• Routing: Route the hose with smooth bends and sufficient free movement throughout the engine and gearbox travel. Keep it away from the exhaust and other heat sources; add heat shielding where space is tight.
• Tightening: Align the fittings before final tightening to avoid twisting the hose. Tighten carefully and do not overtighten the unions or bleed nipple.
• Bleeding: A pressure bleeder or one-way bleed valve helps. Keep the reservoir full and lightly tap the slave cylinder and lines to release trapped air. Confirm a firm bite point and consistent pedal height.
• Track and competition use: Under extreme heat or with a very heavy pedal, a full-length braided hose may provide even greater temperature resistance and pedal definition.

For anyone maintaining or building a Volvo 240, 740 or 940, this is a small but important link in the drivetrain. The correct hose provides predictable clutch feel and reduces the risk of an unscheduled stop, whether the car is used on the road, as a long-term turbo project or in Nordic time attack, drifting or rally competition.
