4. FAQ

Q: Which construction machine does part number 416364 fit for?
A: Part number 416364 oil seal kit is engineered for track‑type excavator main hydraulic pump shaft assembly maintenance work.

Q: What sealing value can part number 416364 bring for the main hydraulic pump?
A: 416364 oil seal kit contains high‑pressure hydraulic fluid inside pump housing, reduces external leakage risk at high‑speed rotating shaft, and stops fine construction dust and humid moisture from entering pump inner valve components.

Q: What raw materials constitute this main pump shaft oil seal kit?
A: Sealing lip adopts pressure‑resistant HNBR hydrogenated nitrile rubber, and supporting steel skeleton uses zinc‑alloy plating treatment for better corrosion resistance under fluctuating pressure environment.

Q: What color presentation will customers get for this sealing repair kit?
A: HNBR rubber sealing pieces are deep matte black, zinc‑alloy plated steel skeleton shows soft silver‑grey metallic surface.

Q: Where is this oil seal kit installed on track‑type excavator?
A: These sealing components are embedded within the annular gap between rotating main pump drive shaft and stationary pump front cover housing bore.

Q: Where is this oil seal kit installed on wheel loader?
A: These sealing parts fit into the annular gap between rotating steering pump drive shaft and stationary pump front housing bore.

Q: How will this sealing kit interact with construction‑site lubricants?
A: Nitrile rubber keeps stable dimensional property and low‑swelling rate against transmission gear oil and conveyor bearing grease.
 

Q: What risk will scratch damage bring to electrophoretic coated shell?
A: Once the coating layer is scratched off, bare steel will corrode gradually, which may lead to seal loosening and unexpected oil leakage.

Q: How well can this full sealing kit block mud, gravel dust and hot gear oil mist on muddy outdoor road job sites?
A: The multi-layer flexible rubber lip scrapes thick mud off the shaft surface, the fully enclosed plated metal shell blocks coarse dust particles, and inner auxiliary rubber layers isolate high-temperature oil mist to protect internal precision gears.
