This is a replacement gearbox breather for the SKK Model 08, also known as the Challenge 08, 24-bolt gearbox. The breather features a 1/4" NPT threaded connection and a hex head for easy installation. Its primary function is to vent the gearbox, allowing air to expand and contract with temperature changes, which prevents pressure buildup that can damage seals. This part is essential for routine maintenance to ensure the longevity and proper function of the gearbox by preventing contamination and seal failure. It is made of plated steel for corrosion resistance.
