Clutch Master Cylinder for Ford New Holland 40 Series and TS Series Tractors SKU: QT409825

When your clutch pedal goes to the floor with no resistance or won't disengage the clutch properly, internal seals have failed and you lose hydraulic pressure that makes shifting possible. Symptoms include a spongy pedal, clutch slippage under load, or complete loss of clutch control that turns your tractor into an expensive lawn ornament. This Carlisle replacement master cylinder restores proper hydraulic pressure to your clutch system, bringing back smooth engagement and complete disengagement that makes shifting possible again.

Why This Part Matters

• Direct replacement for Ford 40 series and TS series clutch systems with precision-bored cylinder that ensures consistent clutch operation
• Specifically designed for LHM mineral oil - never mix fluids as the wrong type destroys seals quickly and this green-tinted mineral oil maintains consistent performance without absorbing moisture
• Using standard brake fluid instead of LHM destroys seals rapidly, making proper fluid selection critical for long-term reliability
• Built to handle the contamination and age factors that cause failure, preventing premature wear of other clutch system components

This cylinder fits Ford 40 series (5640, 6640, 7740, 7840, 8240, 8340) and TS series (TS90, TS100, TS110, TS115) tractors. After installation, bleed the entire system thoroughly to prevent air bubbles that cause spongy operation, and inspect the slave cylinder since master cylinder failure often indicates other components need attention too. S&H Parts has been helping customers restore reliable clutch operation since 1969.
