Q: What internal damage occurs if an excavator continues to run with worn 0928006 piston assemblies?
A: The loose slippers will scratch the swash plate face and tilt inside the cylinder bores, causing rapid copper erosion and deep scoring lines that can ruin the entire pump rotating group.

Q: What quality control checks are needed when inspecting these replacement piston shoes during a major pump rebuild?
A: Workshop mechanics must use a micrometer to check that all piston diameters match within tight factory limits, ensuring equal oil compression across the entire cylinder group.

Q: Does this 0928006 listing include the full set of pistons required for a total pump overhaul?
A: This listing represents the single component unit to allow flexible ordering options, but we highly recommend procurement managers order the full matched set to ensure balanced internal system tolerances.

Q: How does this bimetallic slipper group resist thermal scuffing when operating continuously during hot summer mining shifts?
A: The high-lead bronze composition bonded to the steel head serves as an excellent solid lubricant during brief dry-startup cycles, preventing the piston shoes from welding onto the swash plate face under extreme friction heat.
