Rocker Shaft Seal Ring for Case 55 and 56 Series Tractors SKU: QT400199

A failed rocker shaft seal allows engine oil to leak from the cylinder head area, creating messy external leaks and potentially starving critical valve train components of proper lubrication. This replacement seal ring restores the factory seal to prevent oil loss and protect your engine's top end.

Why Proper Sealing Matters

• Prevents oil contamination of external engine components
• Maintains proper lubrication pressure for rocker arm operation
• Eliminates messy leaks that attract dirt and debris
• Preserves engine cleanliness for better heat dissipation

When your rocker shaft area shows signs of oil seepage or you're doing valve train service, replacing this seal prevents future problems. With over 55 years of experience helping farmers maintain their equipment, S&H Parts stocks the quality seals your Case tractor needs to keep running strong.
