1672781 Single Line Hydraulic Release Bearing Assembly

CRB-053

Pressure builds inside the 1672781 Single Line Hydraulic Release Bearing Assembly the moment the clutch pedal is pressed. Fluid travels along the rigid arm, expands an internal piston and drives the release bearing forward so the clutch disc separates cleanly from the flywheel.

Unlike short-port designs that leave little room for hose movement, the extended arm on this unit creates a clearer exit path inside the transmission housing. The main body still sits concentrically around the input shaft and uses the original three mounting points, allowing the whole assembly to drop straight into place once the gearbox is removed.

Core Functions
Fluid enters through the arm and expands the piston chamber. The bearing advances evenly around the full circle of the diaphragm, lifting the pressure-plate fingers and freeing the clutch disc for gear selection. When the pedal returns, residual spring force retracts the piston so the clutch re-engages without hesitation. The short, centred force path keeps pedal feel consistent and reduces localised wear on the disc. The arm itself simply provides a practical routing solution that keeps the hose away from heat and moving components.

Customer Pain Points Solved
Short-port units often force the hydraulic hose into tight bends or against sharp edges. The arm on this assembly gives extra length and a better exit angle, lowering the risk of chafing or restricted flow.
Incomplete clutch release still causes gear grind and heavy shifts. A worn bearing fails to travel far enough; fitting the 1672781 Single Line Hydraulic Release Bearing Assembly restores full stroke and clean disc separation.
Internal leaks contaminate the clutch disc and create slip or judder. Proper sealing surfaces and correct bleeding after installation keep fluid where it belongs. Soft pedal feel caused by air or degraded seals also improves once the system is bled through the single line.
Workshops that previously replaced separate external cylinders and forks save labour time. One integrated unit with the arm solves the entire release problem. Distributors facing fragmented demand across similar numbers gain cleaner stock turns with this single reference.
