O-Ring for PTO Bearing Assembly on Case MX Series Tractors SKU: QT400204

When your PTO bearing assembly starts leaking transmission fluid or allowing contamination into critical drive components, it's usually this O-ring that's failed. A deteriorated seal lets expensive hydraulic fluid escape while dirt and moisture infiltrate the bearing housing, leading to premature bearing failure and costly PTO repairs.

Why This Seal Matters

• Prevents transmission fluid loss that leads to PTO bearing failure
• Keeps contamination out of sealed bearing assemblies
• Maintains proper lubrication pressure for smooth PTO operation
• Built to handle the heat and pressure of continuous PTO use

Don't wait until bearing noise or complete PTO failure forces expensive repairs. This O-ring is your first line of defense against the contamination and fluid loss that destroys PTO systems. Call us if you need help confirming fitment for your specific MX series model.
