Victor MH-RE31617B4 Valve Stem Seal Positive Type Viton OEM RE31617

The Victor MH-RE31617B4 is a positive-type Viton valve stem seal engineered as a direct replacement for John Deere OEM part number RE31617 (also cross-references RE515329). Designed for use in John Deere diesel engines, this seal delivers precise, controlled oil metering in the valve train to prevent oil from entering the combustion chamber and reduce harmful emissions.

Key Features:

• Positive-type Viton construction — special rubber compound provides superior heat resistance, durability, and oil resistance compared to standard nitrile seals
• Precise oil metering — controls the amount of oil lubricating the valve stem, preventing over-lubrication or under-lubrication of the valve guides
• OEM-equivalent fitment — engineered to match the dimensional and performance specifications of John Deere part RE31617
• Dimensions: 7.75mm ID × 17.1mm OD × 12mm height
• Application: Compatible with John Deere 3029D, 3029T, 4039D, 4039T, 4045D, 4045T, 6059D, 6059T PowerTech diesel engines and many others
• OEM Cross-References: RE31617, RE515329

A worn or damaged valve stem seal allows oil to be drawn down the valve guides and into the cylinders, resulting in excessive oil consumption, blue smoke at startup, and fouled exhaust after-treatment systems. Replacing with a quality Viton seal like the Victor MH-RE31617B4 restores proper engine sealing and protects long-term engine health.
