Clutch Slave Cylinder – 7/8" Iron Clutch Slave Cylinder Assembly, Compatible For Mitsubishi Fuso Canter/for Hyundai County Truck, Replaces ME602994 41700-5H000

Precision OE Fitment for Light/Medium Duty Trucks

This 7/8" clutch slave cylinder is designed as a direct replacement for compatible light and medium duty commercial trucks fitted with manual transmissions. Replaces OE part numbers ME602994, 41700-5H000, and ME605550. Please verify your vehicle‘s part number, mounting style, and transmission type before ordering, as clutch actuation configurations may vary by chassis.

Direct Replacement for a Leaking or Failing Factory Slave Cylinder

Replaces an unit that has lost hydraulic pressure due to internal seal failure,, or external fluid leakage. A failing slave cylinder typically causes a soft or spongy clutch pedal, difficulty shifting gears, the pedal slowly sinking to the floor when held under pressure, the transmission grinding during gear changes, or complete clutch disengagement failure. Installing a slave cylinder restores proper hydraulic pressure transmission to the clutch release fork.

Cast Iron Construction for Heavy‑Duty Reliability

Manufactured from durable cast iron with a ‑resistant finish to withstand continuous vibration, moisture exposure, and under‑vehicle road debris. The robust cast iron body resists warping and cracking under the repeated pressure cycles and high operating loads typical of commercial truck clutch systems.

Hydraulic Clutch Actuation for Manual Transmissions

Restore Proper Clutch Engagement with a Slave Cylinder

The clutch slave cylinder is a hydraulic component mounted on the transmission bell housing of vehicles. It receives pressurised fluid from the clutch master cylinder when the driver depresses the clutch pedal, then converts that hydraulic pressure into mechanical force that moves the clutch release fork. The release fork pushes the throwout bearing against the pressure plate diaphragm spring, disengaging the clutch from the flywheel and allowing the driver to change gears smoothly. The slave cylinder works in conjunction with the master cylinder to form the complete clutch hydraulic actuation circuit.

On many compatible light and medium duty commercial trucks, the slave cylinder is a known wear item. Over time, the internal rubber seals can harden, crack, or begin to fluid internally due to age, heat cycling, or within the hydraulic fluid. The cast iron housing may also corrode where exposed to road salt and moisture, leading to external fluid seepage around the piston bore or the bleeder screw threads. A failing slave cylinder will typically produce a clutch pedal that feels soft or spongy, a pedal that slowly sinks to the floor when held down, difficulty shifting gears, or the transmission grinding during gear engagement — symptoms that left unaddressed can lead to a complete loss of clutch function while the vehicle is on the road.

This replacement slave cylinder is manufactured to OE fitment standards, restoring reliable hydraulic pressure transmission and clutch release function to your truck’s system.

Why Replace Your Clutch Slave Cylinder

Clutch pedal feels soft, spongy, or goes to the floor with little resistance when depressed

Difficulty shifting gears, especially when the transmission is cold or under load

Clutch pedal slowly sinks to the floor when held under constant pressure, requiring pumping to build pressure

The transmission grinds during gear engagement, even with the clutch pedal fully depressed

Fluid residue is visible on the outside of the slave cylinder, the transmission bell housing, or dripping onto the ground beneath the vehicle

Low fluid level in the master cylinder reservoir without any visible external leak from the system (indicating internal fluid within the clutch hydraulic circuit)

You have already confirmed that the clutch master cylinder is functioning correctly, ruled out other possible causes (worn clutch disc, damaged pressure plate, broken release fork, failed throwout bearing), and concluded the slave cylinder is the source of the problem

Converts hydraulic pressure from the clutch master cylinder into mechanical force to move the clutch release fork, disengaging the clutch from the flywheel to permit smooth gear changes in vehicles. This slave cylinder works together with the master cylinder to complete the clutch hydraulic circuit.

Professional Installation Strongly Recommended

Replacement typically requires raising the vehicle, removing the old cylinder from the transmission bell housing, bleeding the clutch hydraulic system to air after installation, and adjusting pushrod length as needed for proper clutch pedal engagement height. Disconnect the before any electrical work. Professional heavy‑duty truck mechanic assistance is strongly recommended for this replacement.
