Updates to the Transfer Case:
• Adapt-A-Case BRNY Case Saver
Accelerated wear of magnesium transfer case housings has been documented anytime internal parts move against the magnesium. This is especially evident in New Venture/New Process 136, 149, 236, 246, 261 and 263 transfer cases. The sharp edges of the aluminum pump locating tabs cut through the soft magnesium, or other times the sharp edges of the OE U-shaped insert wear a larger area above the pump tabs. A small amount of movement of the pump is necessary to keep the pump centered on the output shaft. Any metal in contact with the magnesium causes rapid fretting wear of the soft magnesium, resulting in pinhole leaks. Adapt-A-Case BRNY transfer case pump plate kit eliminates these contact issues and helps distribute the contact area of the pump to the magnesium casing and eliminating the U-shaped steel insert.Warranty:
