1000285721AM E17-6012 Clutch Servo belongs to Clutch Master Cylinder.

 

The 1000285721AM clutch slave cylinder serves as the critical hydraulic actuator in manual transmission systems, converting pedal effort into precise clutch disengagement. This sealed hydraulic unit operates through a carefully orchestrated mechanical sequence:

 

Operational Cycle:

·Pedal Engagement (0.2-0.5 sec response time):

-Driver pressure (typically 80-120N) pushes master cylinder piston

-Generates 800-1200 psi hydraulic pressure through mineral oil/DOT4 fluid

 

·Force Transmission:

-Pressurized fluid travels through reinforced hose (6-8mm ID)

-Acts on slave cylinder piston (∅28-32mm bore)

-Converts hydraulic pressure to 300-400N mechanical thrust

 

·Clutch Actuation:

-Pushrod extends 20-25mm

-Rotates release fork (15-20° arc)

-Compresses diaphragm spring through release bearing

 

Technical Features:

·Bleedless design with self-adjusting preload

·Dual-lip Nitrile seals for leak-free operation

·Hardened steel pushrod (HRC 50-55 surface hardness)

·Zinc-nickel plated body for corrosion resistance

 

Performance Benefits:

·40% reduction in pedal effort vs mechanical linkage

·0.05mm piston clearance for precise modulation

·500,000 cycle durability rating

 

Maintenance Requirements:

·Biennial fluid replacement

·Annual boot inspection

·Clutch service interval verification

 

Failure Prevention:

·Avoid fluid contamination (max 3% moisture)

·Maintain proper reservoir level

·Prevent air ingress during servicing
