Revive Your Classic John Deere with Upgraded Durability from Vintage Parts Revival
 
At Vintage Parts Revival, we're dedicated to enhancing the longevity of iconic machinery through premium replacement parts that honor historical designs. Our John Deere Unstyled Radiator Baffle Plate with Buna-N Gasket is a new production upgrade, featuring a stainless steel (grade 304) oval baffle plate as a direct replacement for part D126R, paired with a durable Buna-N gasket D473R replacement. The original baffle was manufactured from carbon steel similar to A36, which often rusted in the moist upper cap area of the tractor radiator or gas tank, leading to foreign material contamination when it broke away. Over time, restorers have turned to stamping brass baffles for better corrosion resistance, but our stainless steel version offers superior corrosion protection while allowing slightly more strength and flex than the originals—though it may experience some wear at the shaft and cotter pin interface.
The integrated Buna-N gasket, unlike the original fiber/cork material that was sufficient but short-lived, was specially selected for extended life in applications involving water-based ethylene glycol mixtures or gasoline, making it ideal for radiator or gas tank seals. This high-quality gasket provides a reliable seal with reasonable compression from the cap's application, ensuring leak-proof performance under vibration and temperature changes. Together, this assembly prevents coolant surge, overflow, and contamination, delivering modern reliability for your restoration projects without sacrificing authenticity.
Ideal for unstyled John Deere tractors, this upgraded baffle plate with gasket maintains optimal radiator function and protects against rust in challenging environments. Whether you're overhauling a classic A, B, or D series, it elevates performance while respecting the machine's heritage.
