Good To Know
Q: What signs indicate these plungers need replacement? A: Reduced working pressure, excessive pump noise, or oil contamination in the crankcase often signal worn plungers. Checking the plunger surface for fine cracks or wear grooves confirms the need for a new set.
Q: Do these plungers fit other pump brands with the same part number? A: The 47040409 cross-reference may apply to pumps built on shared platforms, but fit and sealing depend on precise dimensions and gland geometry. Always verify compatibility with your specific pump model and serial number before ordering.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
